Evaluation of Pressure Types Impacted on Sediment Supply to Dam Reservoirs: Selected Examples of the Outer Western Carpathians Catchments Area

The proper characteristics of the catchment area dammed reservoirs is great importance when managing their capacity in context enabling functioning, including retention planned amount water and counteracting effects drought. Therefore, detailed analyses covered mountain with varying degrees changes: Goczałkowice on Vistula, Rożnów Dunajec Tresna Soła, thanks to which reasons for differences these changes were determined. For this purpose, data volume suspended load was used. Diversity its transport mainly caused by presence damming structures. Correlation morphological hydraulic indicators carried out, preceded identification all transverse longitudinal structures located catchments upstream individual reservoirs. Analysis geological structure, as well structure land use basins reservoirs, also performed. obtained results allowed preparation recommendations further work, allowing, among other things, an increase retention. key factors maintaining defined, may be useful national plans or programs field drought flood protection.
