Description: About one-third of the global population currently lives in countries which experience conditions of water stress. Such regions, often located within dryland ecosystems, are exposed to the hazard that the available freshwater resources fail to meet the water demand in domestic, agricultural and industrial sectors. Water availability often relies on the retention of river runoff in artificial lakes and reservoirs. However, the water storage in reservoirs is often adversely affected by sedimentation as a result of soil erosion. Erosion of the land surface due to natural or anthropogenic reasons and deposition of the eroded material in reservoirs threatens the reliability of reservoirs as a source of water supply. To guarantee future water supply, a quantification of the sediment export from large dryland catchments becomes indispensable. Objectives: The main objective of the SESAM project is the development of a model system that enables the assessment of sediment production in catchments, sediment transport in river system and sediment retention in reservoirs for meso-scale catchments in semi-arid and sub-humid regions. The necessary data for model development and application are derived from extensive data collection programs within experimental catchments, dryland rivers and reservoirs in Spain and North-East Brazil. Contributions of Section 5.4. Engineering Hydrology are: Extension of the hydrological model WASA (Güntner & Bronstert, 2004) that has been specifically developed for the environmental characteristics of semi-arid areas with components representing erosion and sediment transport processes at the hillslope to the basin scale. Measurement devices for suspended sediment transport. Landscape characterization and discretization for hydrological modelling based on remote sensing data.
