Information - HS3 Quantification of anthropogenic impacts on catchment hydrology and water quality for sustainable catchment management
In recent years hydrological processes in river basins have increasingly been studied in order to quantify the possible impacts of changes in land use, land cover or soil surface conditions and urbanization on catchment hydrological processes, water quality and on extreme hydrological events (floods and droughts). One central aim of these investigations is the development of concepts for sustainable catchment management. Experimental catchment studies as well as the application of hydrologic or eco-hydrologic models have been used to achieve this goal.
Against the background of the European Framework Directive (WFD) it becomes even more important to make this knowledge available for future decision making precess. Therefore this session also aims at the evaluation of available methodologies used during the early phase of the implementation of the WFD. Applicable methodologies for characterising the different sources (diffuse, points) of pollution, and for conducting an impact analysis are sought.
Therefore this session welcomes contributions on the following particular issues:
- Anthropogenic influence on water, erosion and pollutant fluxes on catchment scale including the identification of significant sources of point and diffuse pollution for groundwater and surface water including the impacts of urbanization on hydrologic properties of catchments
- Experimental catchment studies to analyse the impact of land use change or management practice on water quantity and quality
- Catchment modelling or modelling of hydrologic processes under the influence of land use/land cover change or management practice
- Conservation strategies to reduce diffuse pollution of water bodies on the catchment scale
- Compilation and evaluation of land use change or management practice scenarios
- Scenario analyses of land use change or management practice in modelling exercises
- Consideration of parameter uncertainty for of land use or management practice studies
- Modelling tools and sustainable catchment management strategies in order to achieve the goals of WFD
- Multi-disciplinary approaches towards sustainable catchment management
- Strategies how to transfer methods/results from small catchment experience to larger scales.
