Hydrological and geomorphological processes in natural and human-modified slopes and landslides
This session aims to discuss precipitation-induced hydrological and geomorphological processes such as different types of landslides on local and regional scale in natural and human-modified landscapes. Landslides and mobilized in-stream sediment represent an important source of hazard for economic activities, infrastructures and population living on the slopes and in adjacent lowland areas.
Precipitation-induced hydro-geomorphological processes can deliver large volumes of sediment to the stream network and are often associated with the occurrence of shallow landslides and channelized debris flows. Water circulation within a catchment and the resultant transient changes in both shallow and deep hydrological systems is the most common controlling and triggering factor of slope movements and debris flows. However, incorporation of hydrological process knowledge in these processes, such as water-rock interaction, water storage, dynamic preferential flows or the influence of frost conditions to name a few, still lags behind. Detailed monitoring, analysis and modelling of hydro-geomorphological processes are required to improve our understanding and prediction of the spatio-temporal patterns of the hydro-geomorphological processes.
The purpose of this session is to gather contributions aimed at understanding the influence of environmental and anthropic factors on the hydro-geomorphological response of natural and human-modified slopes and catchments. We invite research ranging from unsaturated zone, hillslope processes and regional hydrology which are applied to landslide research in a broad sense: ranging from soil slips, debris flows and to large scale deep-seated slope deformation. The session wishes to represent an opportunity for sharing and exchanging knowledge, approaches and achievements between experts and young scientists that may be useful in scheduling proper landslide risk prevention and mitigation strategies in human-modified catchments.
