RESERVOIR SEDIMENTATION ASSESSMENT GUIDELINE - Aneel

Reservoir Sedimentation Assessment GuidelineFigure 7.14 – Example of sedimentometric data regionalization – Relation betweendischarges and load discharges in basins neighboring Rio Doce basin –Measurements from 1960 to 1971 (Carvalho, 1994)Rio = riverPosto = stationPeríodo = periodFor data regionalization concerning different basins, one should try to verify thecurves that may be obtained and use the one whose features are compatible with thegaging station position. In the example for Figure 7.15, the higher curve was used forobtaining the sediment production in dam construction sites in Doradas River. Note thatthe curve reports a P s value corresponding to the gaging station at that stream (point 6).ANEEL – Brazilian Electricity Regulatory Agency / SIH – Hydrologic Studies and Information Department38
