The study and the qualification of the spatial distribution of accumulated bottom sediments in small reservoirs is considerably not only on the design stage, but also during the of operation. The majority of investigative papers concerns to the distributions of the accumulated sediments in average and large water reser-voirs. In this work was introduced and describes for the help of the Dendy's method the spatial distribution of the accumulated sediments in the main water reservoir at Zesławice in the period before and after his desilting.In consideration of building the side reservoir, which to take of the functions of the main reservoir in the period its desilting and reconstruction, the conditions of the flow of the water and the sediment was change. It is had the impact on the dis-tribution of the bottom sediments in the main reservoir.It was showed in this work, on the basis of the executed measurements of silting and the determined the silting degree of the main reservoir, that the decrease the intensity of silting studied reservoir had taken place in the result of the split of water and sediment and it also influenced on the change of the spatial distribution of the sediment deposited. It was ...
