Modelling the impact of climate change on sediment yield in a highly erodible Mediterranean catchment

摘要: The assessment of climate change impacts on the sediment cycle is currently a primary concern for environmental policy analysts in Mediterranean areas. Nevertheless, quantitative still complex task. aim this study was to implement model by taking advantage proxy information provided reservoir bottom deposits and use it catchment. utilised catchment that drains into large reservoir. depositional history reconstructed used sub-model implementation. results were compared with gauged suspended data order verify robustness. Then, coupled future precipitation temperature scenarios obtained from models. Climatological outputs two emission (A2 B2) simulated reference scenario. Model showed general decrease soil moisture water discharge. Large floods, which are responsible majority mobilisation, also decrease. Sediment yield clear reduction under A2 scenario but increased B2 computed specific control period 6.33 Mg ha−1 year−1, while scenarios, 3.62 7.04 Mg ha−1 year−1, respectively. Furthermore, transport an increase its time compression, i.e. stronger dependence total largest event contributions. This shows methodology implementing distributed exploiting sedimentation volumes. can be applied wide range catchments, given high availability data. Moreover, how such framework study, providing measure impact erosion yields.
