Summary:

Paper presents results of measurements and analyses of sediment transport flowing to the water small Mściwojów reservoir. Measurements of suspended and bed load transport on two tributaries (stream Zimnik and Wierzbiak) to this reservoir showed that annually it gets to this one about 167 T of sediment. Part of suspended load in total transport is about 97%. From the self bathymetry author’s studies follows that this reservoir is better intensively silted up, mainly in settling tanks and pre-dams. It causes the continuous reduction of its storage and shows on further necessity operation of the bathymetry reservoir bowl measurements and quantity, and kind of flowing sediment. The last studies at Mściwojów reservoir showed that it has been partly elutriated in part, where are the settling tank, and dumps have been deposited in its region.
