ABSTRACT

Prediction of reservoir silting should also determine distribution of bottom sediments. Existing methods of predicting sediment distribution most frequently concern large reservoirs. In result of many-year measurements of silting of the reservoir at Krempna on the Wisłoka river the rate of its capacity reduction was determined. Results of silting measurements allowed for an assessment of distribution of sediment trapped in the reservoir. Distribution of the reservoir bottom sediments was described by Dendy’s method and potential application of Roseboom-Annandale method for predicting sediment distribution in a small reservoir was estimated. Computations using the field data on sediment volume deposited in individual segments of the reservoir at Krempna were conducted to verify Roseboom-Annandale method. Basing on sediment volume trapped in the reservoir the degree of its silting was calculated for subsequent years of its operation. On this basis the rate of silting the reservoir at Krempna was calculated and the change of silting degree was determined during its operation time.

Key words: small water reservoir, silting, silting degree, sediment deposit distribution.
