Discharge regime assessment for purposes of reservoir sediment trap efficiency estimation
Original language description
Proportion of sediment trapped in reservoirs is expressed by Trap Efficiency (TE). Brune (1944) introduced the methodology based on statistic evaluation of data from high number of reservoirs. Trap efficiency is expressed graphically and as an input Capacity inflow ratio is considered. This variable is a ratio between reservoir storage volume and mean annual discharge. Dendy (1978) added more reservoirs and developed analytical expression of the method. The problem with calculation of sediment trap in reservoirs over large catchments is a lack of input data. Both storage volume of reservoirs and mean annual discharge are usually available only for small portion of the total number of reservoirs in conditions of the Czech Republic. In this paper, the methodology on deriving mean annual discharge in small streams is presented. Using the map of specific runoff values is the typical way of determining runoffs in upper catchments. Unfortunately, detailed map is not available in the Czech Re
