The transfer of sediments and associated contaminants plays an important role in catchment ecosystems as they directly influence water quality, habitat conditions, and biogeochemical cycles. Contaminants may include heavy metals, pesticides, nutrients, radionuclides, and various organic, as well as organometallic compounds. The environmental risk posed by sediment-bound contaminants is largely determined by the sources and rate at which sediments are delivered to surface water bodies, the residence time in catchments, lakes, and river systems, as well as biogeochemical transformation processes. However, the dynamics of sediment and contaminant redistribution is highly variable in space and time due to the complex non-linear processes involved. This session focuses on sources, transport pathways, storage, re-mobilization, and travel times of sediments and contaminants across temporal and spatial scales, as well as their impact on freshwater ecosystems.

This session particularly addresses the following key themes:
1) Sources and Pathways of Sediment and Contaminant Transfer
Understanding how sediments and contaminants originate from natural and human sources (e.g., agriculture, urban areas, mining, industry) and move through the land, river, lake, and reservoir continuum.
2) Transport Dynamics and Environmental Controls
Investigating the transport, retention, remobilization, and transformation of sediments and contaminants, including the influence of biogeochemical processes, human activities (such as hydropower and flood management), and changing environmental conditions.
3) Innovative and Cost-effective Monitoring and Modelling Methods
Developing and applying novel, low-cost, and open-source methods to quantify sediment and pollutant fluxes across different spatial and temporal scales.
4) Impacts on Ecosystems and Landscapes
Assessing how sediment and contaminant dynamics affect river systems, floodplains, riparian zones, in-stream ecosystems, landforms, and geomorphological processes.
5) Long-term Change and Human Influence:
Using sediment archives, sediment budgets, and catchment-scale analyses to evaluate historical trends and understand the effects of human activities and environmental change on sediment and contaminant dynamics over time.

Soil erosion is a key driver of land degradation, leading to a cascade of impacts from on-site soil loss and reduced agricultural yields to off-site consequences such as flooding and sediment and contaminant pollution of aquatic environments. The environmental, economic, and societal impacts of soil erosion require a comprehensive scientific understanding of the physical processes controlling soil detachment, transport, storage, and redistribution from hillslopes to catchments, lakes, and estuaries.
This cross-disciplinary session covers the latest scientific developments in soil erosion and sediment delivery. By integrating hydrology, geomorphology, soil sciences, and biogeosciences, we aim to unify all driving forces of land degradation and catchment particle-bound transport.
Our goal is to bridge the gap between plot-scale soil loss and catchment sediment routing, linking short-term monitoring with long-term observations. Advancing this process knowledge connects methodological developments to conceptual frameworks, promoting sustainable management.

The following topics will form the core areas of presentation and discussion:
• Measurements and Tracing: Field and lab experiments developing process understanding (e.g., interrill to gully erosion) and catchment sediment tracing techniques.
• Monitoring: Short- to long-term assessments tracking landscape changes via local field assessments, UAS, and broad-scale remote sensing.
• Modelling Approaches: Innovative simulation techniques, from empirical and process-based to data-driven, addressing runoff, gully erosion, sediment transport, and catchment sediment budgets from plot to global scales under current and future climate scenarios.
• Sediment and Contaminant Dynamics: Quantification of sediment transit or residence times, storage, remobilisation, and the biogeochemical controls of associated contaminant transport impacting riverine and lacustrine ecosystems.
• Mitigation, Restoration and Impacts: Evaluation of conservation strategies, including successes and failures in addressing the on-site and off-site impacts of land use change and disturbances (e.g., agriculture, forestry, mining, urbanisation, wildfires).
Ultimately, we explore conservation strategies that support stakeholders and global initiatives, including the EU Soil Monitoring Law, Land Degradation Neutrality by 2030, and the UN Decade on Ecosystem Restoration (2021-2030).

Enhanced weathering (EW)—the application of crushed silicate rocks to soils and other terrestrial environments—has emerged as a promising approach to atmospheric carbon dioxide removal, with estimates suggesting the potential for gigaton-scale removal annually. Research in this field is advancing rapidly, yet substantial uncertainties remain, ranging from dissolution kinetics in soils to the transport, transformation, and fate of weathering products in soil and freshwater systems. Building on the scientific exchange initiated during the previous edition, this session aims to continue providing a forum for advancing research and discussion on these challenges. We invite theoretical, experimental, modeling, and field-based contributions addressing not only the carbon removal potential of EW, but also its environmental co-benefits, possible risks, monitoring and verification, and applications in understudied regions. By bringing together diverse disciplinary perspectives, the session aims to foster collaboration and advance a more comprehensive understanding of EW's role in scalable, safe climate mitigation.

Soil health can be assessed in many ways, depending on the perspective from which the soil is considered. It may focus on the biological diversity and activity of different soil organisms, and their ability to contribute to soil functions such as nutrient availability, or the presence or absence of pollutants. Soil can also act as a buffer for various substances and act as the transport medium for the transport of water, solutes and particles. However, hardly ever is soil health looked at through a soil physics lens, which is the aim of this session. The goal is to identify the “physics-shaped” knowledge gaps and blind spots in the field of soil health and discuss what contributions the discipline of soil physics has to offer, beyond bulk density.

We are looking for contributions addressing topics like:
- What are current methods to understand soil health, and how can they be related to physical soil properties and processes?
- What are promising parameters (besides texture and bulk density) that can serve as physical proxies for soil health?
- What could simple field-tests be?
- Would there be a need to adapt physical soil health indicators for different textures?
- How can soil physics contribute to accessible and interdisciplinary approaches for monitoring soil health?

Soil structure and its stability are important aspects of soil health as they regulate key soil physical, chemical, and biological functions. This includes water retention, hydraulic conductivity and gaseous transport, nutrient cycling, redox dynamics, erosion resistance, and root penetration. The arrangement and connectivity of pores, minerals, and organic matter govern the exchange of water, gases, and solutes within soils and provide habitat for soil biota, which in turn actively modify and engineer the pore network. These interactions create dynamic feedbacks between soil structure and ecosystem functioning.

Soil structure evolves continuously across spatial and temporal scales through the action of roots, soil organisms, land management, and abiotic drivers such as wetting and drying cycles. These processes alter pore architecture and aggregate organization, thereby modifying soil properties and functions over time. Recent advances in imaging, geophysical methods, experimental approaches, and process-based modelling have substantially improved our ability to observe and quantify these dynamics. Nevertheless, many of the mechanisms linking soil structure development, degradation, resilience, and soil functioning remain poorly understood.

Understanding the processes and feedbacks governing soil structure dynamics is essential for developing climate-smart and resilient soil management strategies. In this session, we invite contributions on the formation, stabilization, degradation, and evolution of soil structure and its associated functions across all spatial and temporal scales. We particularly encourage contributions integrating complementary measurement techniques (e.g., geophysics, digital image correlation, X-ray CT), novel modelling concepts, or approaches that bridge scales.

Special focus lies on:
• feedbacks between soil structure dynamics and soil biology,
• effects of land use and management on soil structural development and associated soil functions,
• biological, hydrological, and mechanical processes shaping pore architecture and structural resilience,
• integration of complementary measurement techniques and modelling approaches across scales.

Soil is a dynamic porous media in which its structure plays a key role in controlling soil functionality. As many functions are related to the transport and storage of fluids, we often focus our research in soil physics on the pore space itself ignoring the delicate yet dynamic structure of interconnected solid particles. In this session we aim to look at the mechanical properties and processes that lead to soil structure formation, stabilisation and degradation on various scales ranging from interparticle to bulk/pedon-scale including the assessment of mechanical soil properties on field to regional-scale. We are looking for contributions addressing topics like:

- root/fauna-soil bioturbation mechanical processes and the energic inputs required to generate biopore spaces/structures
- stabilising mechanisms in the rhizosphere and mechanical reinforcement of soil by root networks, rhizodeposition, or microbial extracellular polymeric substances
- the role of pore water pressures and matric potential on soil deformation
- Mineral (grain-grain) / organic-mineral interactions and how they are controlled by the chemistry of pore water and surface charges
- Soil compaction assessment in forestry (skidding tracks) and agricultural soil management including new approaches to model/estimate spatial distribution of (sub)soil compaction
- The effects of compounds, colloids, or microplastics on soil aggregate stability and mechanical behaviour
- Modern and emerging techniques like rheometry, digital image correlation, diffraction stress measurements, aggregation and deformation modelling as well as geophysical approaches to assess soil compaction from the profile to the field scale

Life in soil modifies its physical environment to optimize growth and reproductive conditions. Especially in hotspots of biological activity, soil organisms induce remarkable alterations in soil structure and functions. Elucidating the underlying mechanisms forcing such adaptive modifications, and exploring the feedbacks between the drivers, offers an exceptional opportunity to advance our understanding of fundamental physical and biological processes across scales.
We seek contributions linking biological processes and soil physics at any spatial and temporal scale. For example, insights into how the rhizosphere and its microbiome control fluxes beyond the pore scale; on the role of biological soil crust in regulating infiltration and limiting soil erosion across vast areas of the earth’s surface; on how bioturbation shapes soil hydraulic characteristics over years and decades.
Topics of the Soil Biophysics session include but are not limited to:
1. Root growth
2. Microbial activity
3. Bioturbation
4. Virus dispersal
5. Resource allocation
6. Soil water dynamics
7. Soil structure formation
8. Biological soil crusts
9. Rhizosphere interactions
10. EPS (incl. mucilage)

The aim of this session is to highlight the potential of interdisciplinary approaches to address current and future challenges in soil science and to foster scientific exchange across disciplines.

The type of flow (homogeneous versus preferential flow) is expected to have a major impact on pollutant transfer. We expect homogeneous flow to favor pollutant access to reactive particles and, thus, enhance pollutant retention. Preferential flow also called macro-pore flow, non-equilibrium, unstable flow or funnel and fingered flow, happens when water and solutes move through a porous medium with a limited number of fast pathways instead of having a uniform distribution. These pathways can be induced by biotic (e.g. earthworm and roots) and abiotic factors and processes (e.g. wet-dry and freeze-thaw cycles, lithology and structure) and they vary in space and time. They can carry substantial movement of water and solutes in both vertical and horizontal directions under saturated or unsaturated conditions and can dominate the flow and transport processes across a wide range of scales. As a result, preferential flow may regulate the mobility, distribution or removal of solutes, nutrients or contaminants. Similarly, preferential flow may affect the efficiency of salt precipitation or dissolution processes. Understanding preferential flow processes cannot be overstated, considering its relevance to the fate and transport of solutes, nutrients and contaminants in agricultural land, landscapes, catchments, mine waste covers and tailings storage facilities.
This session welcomes studies on experimental and theoretical challenges to identify, quantify, and model the effect of flow type on solute, nutrient and contaminant transport in porous media (e.g. soil, mine wastes, waste rocks and rocky and gravelly materials) across scales (from pore scale to catchment scale). The session accepts studies on but not limited to the following topics:
• Effects of flow type within the soil-plant-atmosphere continuum and their consequence for solute, nutrient or contaminant transport in the saturated and unsaturated zone;
• Coupling the physical processes of preferential flows and geochemical processes for improving the understanding of solute sorption and desorption, mineral precipitation and dissolution;
• Modelling of different types of flow and their effects on mass transport across scales, from pore to pedon scale and entire catchments and landscapes.
• Transport of particles and colloids, including nanoparticles, and the influence of flow type, in particular preferential and non-uniform flow, on their mobility, retention and remobilization.

Preferential and non-uniform flows are widespread features of natural and engineered porous media and may arise from biotic factors, such as roots and soil fauna, abiotic processes including wetting-drying and freeze-thaw cycles, lithological and structural heterogeneity, as well as anthropogenic activities such as tillage, cultivation practices and landforms construction. Preferential and non-uniform flows can strongly affect water redistribution and the transport of solutes, nutrients and contaminants. Preferential flow pathways may develop and interact over a wide range of spatial scales from the pore scale to soil profiles and entire catchments, while their occurrence and relevance may vary over time, from individual hydrological events to seasonal and interannual dynamics.
This session welcomes experimental, theoretical and modeling studies aimed to improving the understanding, characterization and quantification of preferential and non-uniform flows in porous media across scales. Contributions are welcome on:
• Understanding the geometry, connectivity, formation and temporal dynamics of flow in fissures, fractures, macropores and other preferential flow pathways;
• Understanding the role of physical, biological and geochemical processes in the dynamics of macropores and fracture networks;
• Experimental methods for characterizing heterogeneous pore structures and hydraulic properties, including tracer, imaging, and infiltration-based approaches;
• Conceptual, analytical and numerical approaches for modelling preferential water flow from pore and pedon scales to hillslopes, catchments, and landscapes;
• Approaches linking measurements and models and addressing spatial heterogeneity, temporal variability, and scale transitions in preferential flow processes.
• Development of non-invasive and geophysical techniques, including electrical resistivity tomography and ground penetrating radar for identifying and monitoring preferential flow pathways in porous media.

Subsoils - defined as soil layers below 30 cm or mineral soils - contribute to more than half of the total soil carbon stocks and store substantial amounts of nutrients and water. Despite the critical ecosystem services they provide, including long-term carbon storage, water and nutrient supply to plants, and habitat for biological communities that can differ from the topsoil, they remain under-represented in research. The under-sampling is usually justified by assuming a negligible contribution to ecosystem services. A key factor underpinning many of these ecosystem services is the structural connectivity between topsoil and subsoil, particularly the continuity of macropores, mainly biopores (e.g. earthworm burrows and root channels), which influences water infiltration, root access to deeper horizon and nutrients resources, and the transport of solutes. Compared with the topsoil structure, which can be regularly disturbed (e.g. tillage) and reformed, the subsoil structure might persist over longer timescales and changes slowly unless woody perennials are present, making it a potentially important lever for soil management and climate change adaptation under increasing climate variability and uncertainty. Yet, subsoil properties, functions and their dynamics remain poorly characterized and quantified.

In this session, we aim to bring together studies across disciplines, including soil physics, soil biology, hydrology and biogeochemistry and the connectivity to land use and land management to shed light on the subsoil structure and dynamics and, more broadly, on the role of subsoils in terrestrial ecosystems. We invite experimental, observational, and modeling studies exploring subsoil processes and structural dynamics, including interaction between biological drivers (e.g. roots, soil fauna and microorganisms) and hydrological, carbon and nutrient cycling processes across agricultural, grassland, forest and other terrestrial ecosystems.). Particular attention will be given to studies that highlight the importance of subsoils and the structural pathways connecting them to the broader soil–plant–atmosphere system. We also welcome, imaging studies, synthesis work and reviews addressing deep soil horizons and their roles in nutrient cycling, climate change responses, and ecosystem resilience.

The radioactive materials are known as polluting materials that are hazardous for human society, but are also ideal markers in understanding dynamics and physical/chemical/biological reactions chains in the environment. Therefore, man-made radioactive contamination involves regional and global transport and local reactions of radioactive materials through atmosphere, soil and water system, ocean, and organic ecosystem, and its relations with human and non-human biota. The topic also involves hazard prediction, risk assessment, nowcast, and countermeasures, which is now urgent important for the nuclear power plants in Ukraine, the Middle East, etc.

By combining long monitoring data (> halftime of Cesium 137 after the Chornobyl Accident in 1986, 16 years after the Fukushima Accident in 2011, and other events), we can improve our knowledgebase on the environmental behavior of radioactive materials and its environmental/biological impact. This should lead to improved monitoring systems in the future including emergency response systems, acute sampling/measurement methodology, and remediation schemes for any future nuclear accidents. Furthermore, the discharge of ALPS-treated water into the ocean, carried out as part of the decommissioning of the Fukushima Daiichi Nuclear Power Station, has attracted international attention and demonstrated that decommissioning a nuclear power plant that has suffered an accident requires a fundamentally different approach from that of a conventional decommissioning. Studies on past nuclear contamination events and other environmental radioactivity datasets are also welcome.

(g) Measurement Techniques (instrumentation, multipoint data measurements);
(h) Ecosystems (migration/decay of radionuclides).

Land surface processes play a crucial role in shaping Earth's climate system, mediating land-atmosphere interactions, and driving terrestrial water-carbon-energy feedbacks. Land Surface Models, as core components of Earth System Models (ESMs), influence climate projections in benchmarks such as the CMIP7. However, land hydrology and its interactions with other components of the Earth system (e.g. biosphere, biogeochemical cycles) remain poorly represented in most ESMs, potentially inducing erroneous responses to anthropogenic climate forcings at global to local scales and leading to misrepresentations of droughts and floods. For instance, ESMs do not represent the observed decline of groundwater levels in water-limited regions that threatens groundwater-dependent ecosystems and exacerbates drought persistence, thereby increasing the risk of ecosystem shifts and progressive desertification. This crosscutting session provides an open, interdisciplinary platform to bridge the gap between hydrologists, hydrogeologists, ecohydrologists, and climate modelers.

We invite observational, theoretical, and numerical modeling contributions that advance the integrated representation of hydrological, hydrogeological, biophysical, and ecosystem processes within land surface models across spatial and temporal scales. Key areas of focus include the representation of the soil-plant-atmosphere continuum, plant hydraulics, vegetation stress dynamics, and biosphere-mediated moisture recycling, alongside subsurface hydrogeology such as explicit groundwater-table dynamics, lateral flow, and deep aquifer linkages. Contributions addressing human-water-ecosystem interlinkages (e.g., groundwater abstraction, irrigation, land-use change), high-resolution ESM configurations, advanced observational networks, and emerging AI/machine learning techniques are also strongly encouraged.

The overarching aim of this session is to overcome historical disciplinary silos and establish a shared agenda across modeling communities. By aligning interdisciplinary priorities, addressing cross-scale parameterization challenges, and improving the evaluation of land-based mitigation and adaptation strategies, this session seeks to define future needs and collaborative opportunities for the next ESM generation.

Why do past climatic changes produce different societal outcomes across regions and through time? This session focuses on the pathways and feedbacks linking climate change, water availability, ecosystem productivity, resource landscapes, human agency, and societal changes during the Holocene and beyond. We invite empirical, theoretical, and modelling studies that identify these processes across past and present human-environment systems. Of particular interest are studies that integrate palaeoclimate and environmental records with archaeological, historical, or societal evidence; examine thresholds, feedbacks, and nonlinear responses; or use process-based, agent-based, network, complex-systems, and data-driven approaches to connect environmental forcing with human decision-making and societal change. By bridging together climate, environmental, and social perspectives, this session aims to advance a process-based understanding of why climatic changes produce diverse societal trajectories under different environmental and social context.

Thermal remote sensing is an increasingly established technique employing passive sensors to deriveEarth’s surface properties from the radiation emitted in the Thermal Infrared (TIR) domain. Its main focus is the thermal state of an object or surface, together with the associated surface temperature and emissivity. These properties are relevant across geological, environmental, climatic, agricultural, biological, and engineering applications.

Recent technological advances have driven the development of TIR remote sensing: satellite sensors and data infrastructure systems can now acquire and manage large volumes of high-fidelity TIR data at a wide range of spatial and temporal resolutions. Besides airborne and ground-based systems, Unmanned Aerial Systems (UAS) are increasingly used as versatile platforms that combine high spatial resolution with flexible temporal revisit. Together with a growing catalogue of current and upcoming missions, this makes it a timely moment to take stock of where the field stands.

This session addresses established and emerging research directions in TIR remote sensing and discusses the community's upcoming challenges. We welcome contributions on new frontiers, case studies, and data-integration analysis related to:

• Geosciences: volcanoes, hydrothermal systems, geothermal potential, mineral exploration, rare earths, cryosphere.

• Climate, Urban Systems, and Ecosystems: urban heat islands, global warming impacts, ecosystem stress, forest health, fire risk assessment, water management.

• Agriculture and Precision Farming: crop stress monitoring, irrigation management, soil analysis and pest/disease monitoring.

• Technological and Methodological Innovations: new sensors for satellite, airborne, UAS and in-situ platforms, multi-platform and/or multi-sensor data integration, Cal/Val activities.

• Data Processing and Infrastructure: approaches for managing and processing large TIR datasets, data fusion techniques, advanced algorithms for atmospheric correction and temperature and emissivity separation.

Multi-disciplinary studies and contributions from Early Career Scientists are especially welcome.

This session aims at presenting current and forthcoming novel uses of spaceborne hyperspectral imagery acquired over several scales, especially the EnMAP mission, for geosciences and environmental applications. EnMAP provides high quality spectral data at 30 m spatial resolution covering the visible, near- and shortwave infrared regions with nearly global coverage and some regional time-series achieved after 5 years in orbit. Abstracts are solicited toward the characterization and quantification of geo- and bio-physical surface properties related to but not limited to soil and soil health, soil pollution, plastics, critical metals and minerals detection, carbon content in soils, hazards, volcanology, snow and ice properties, as well as vegetation, marine and atmospheric studies.

Soil health is an active priority within the policy landscape of Europe. The EU Soil Strategy and the EU Soil Monitoring and Resilience Directive (SMD) have real potential to support changes in soil health for forest, agricultural and urban land-uses, especially if they are effectively informed by scientific evidence. Yet the translation of soil knowledge to be simultaneously actionable, evidence-based and context-relevant across spatial and temporal scales is a non-trivial task, both with respect to process and content. This session is hosted by members of the PSOILICY project (connecting soil science and policy through national hubs, policy labs and tools for evidence-based soil governance) and invites contributions from researchers working on soil health within the science-policy interface. Presentations highlighting mechanisms for policy support, examples of soil knowledge translation, frameworks or platforms for providing policy-relevant soil knowledge, as well as digital, data-driven and AI-enabled approaches for integrating, interpreting and delivering soil knowledge for policy use, are welcome. Presentations addressing the communication of scientific uncertainty in policy are particularly encouraged.
