Sedimentary processes and transport mechanism in aquatic environments are key features for various research disciplines, e.g. in geomorphological and paleoclimatogical research or in hydraulic engineering. An accurate evaluation of sediment fluxes of the study site is fundamental for the development of sediment budgets or the calibration and validation of numerical simulations.
Innovative measurement techniques and monitoring concepts are important tools to determine the transport processes in rivers, lakes and reservoirs, estuaries as well as maritime and coastal environments. However, the used techniques and concepts have to be selected carefully and have to be adapted to specific in-situ conditions due to the individuality of each field site. As a consequence, monitoring concepts often need to be extended to other measured variables e.g., in order to evaluate discharge - sediment flux rating curves or to review assumptions made for the sediment yield coming from the catchment. An additional focus is the measurement based determination and evaluation of bed load and suspended load transport, morphological changes and morphologically relevant processes like bed armouring, colmation, consolidation, flocculation, re-suspension or hindered settling.

The main goal of this session is to bring together scholars conducting innovative research. Therefore, contributions are appreciated with a particular focus on single and combined measurement techniques, on post-processing methods as well as on innovative and advanced monitoring concepts. Furthermore, we welcome contributions that are presenting recent results on methods for the evaluation of sediment budgets, sedimentary as well as on morphodynamic processes in open water environments in a temporal and spatial scale.

Topics that are of special interest may include measurement based determination and evaluation of
- suspended sediment transport and concentrations in open water environments, e.g. with optical, acoustical and traditional sampling methods;
- bed load transport, e.g. with bed load samplers, sediment traps and tracer stones;
- bed material, e.g. with mechanical bed material samplers or freeze core technique;
- critical bed shear stress of cohesive sediments, e.g. with benthic flumes or miscellaneous devices;
- morphological changes like reservoir sedimentation, bank erosion or bed armouring,
as well as the comparison of different measurement devices and methodologies;
- measurement networks / multiple point datasets;
- monitoring concepts including case studies;
- calibration of measurement data;
- critical discussion and information exchange regarding measurement techniques and data sets.
