Simulation of Water Soil Erosion Effects on Sediment Delivery to Dobczyce Reservoir

چکیده
Synoptic information on suspended matter inflow into reservoirs is important because of the potential storage capacity reduction and water contamination. Such prognosis is difficult to obtain only from in situ measurement. This can be solved by modeling water soil erosion effect using Digital Elevation Model, climate data, soil type parameters and land-use/land-cover data obtained from remote sensing multitemporal imageries. To predict sediment yields from watersheds a calibrated model is needed. The paper presents a study related to the Dobczyce Reservoir, located in the southern part of Poland. In 1980s detailed measurements of sediment yields in its immediate watershed rivers were done. We tried to calibrate an erosion model to predict sediment loads. From many existing soil erosion modeling approaches which could be used as a tool for sediment delivery estimations, the RUSLE approach together with sediment delivery ratio estimation was chosen. The results obtained show the existing potential of this simple approach to predict the sediment delivery to Dobczyce Reservoir from its immediate watershed.

In order to better understand Cu behaviour in the submontane, eutrophic Dobczyce dam Reservoir (southern Poland), speciation measurements of Cu in the water and the sediment were conducted. To investigate the partitioning of Cu in the main components of the sediment, a scheme of VI-step sequential extraction was used. In addition, other physical and chemical parameters of the water, such as tem...

Extended abstract 1- Introduction The Soil surface characteristics have significant effects on the erosion process. The wide areas of watershed soil surfaces are covered with considerable amounts of rocks and pebbles. Surface rock fragments, resulting in water connectivity, change during the erosion process. Rock fragments on the soil surface may increase the infiltration and reduce soil loss...
