Work plan
Collection and investigation of sediment budgets in mountainous watersheds. It focuses on the main La Baells watershed and two additional reservoirs, Sau and Talarn, with limited available data. Analyzes existing data on erosion yields in the watersheds and sedimentation amounts in the reservoirs, along with factors like rainfall, lithology, land use and cover, and climate.
Development of a computational tool to simulate erosion processes in mountainous areas. It uses data obtained in WP1 in two stages: identification of dominant processes and model development. This model is spatially distributed and considers two temporal scales: event-based and annual.
Verification, calibration, and validation of the model. It uses data sets from WP1 and other previous field data for incorporation. It verifies the code with a test data set and defines a calibration procedure focused on simplicity and efficiency.
Analysis of future projections of climate and land use conditions in the three study areas. It uses existing regional climate models and specific scenarios (SSP1-2.6 and SSP5-8.5) for future climate conditions, and employs IDRISI TerrSet software and the medLDM model to project future land use.
Application of the sediment budget model to the three study areas, considering future changes, primarily in entire watersheds but also in sub-watersheds.
Evaluation of the impacts of future changes in climate and land use on the sediment budget in the three watersheds. General conclusions will also be drawn about the sediment budget in other water reservoirs in Spain.
