Abstract

Suspended load in water are a problem dam reservoir management. Accordingly a pre-construction study on suspended load is needed for dams and other hydraulic structures. There are several methods all of which need the results from the field sampling from the river under study or the conjunctive rivers. Because of limited data, interpolation and/or extrapolation will normally be necessary.
In this research, regarding the absence of gauges on SeydonRiver, data from other stations in the basin were used. The result was used on the area-ratio basis. This study was done using single line Sediment Duration Curve (SDC), double line and seasonal SDC, and, FAO methods. The result are then compared to the PESIAC method resulted in the selection of the best method for study area.
