Abstract

Relationships between suspended sediment and rainfall in a given watershed are influenced with catchments and rainfall characteristics. Estimation of suspended sediment load causing a rainfall event is necessity in hydraulic structures. In the present study, variations of suspended sediment for Garan river watershed (an upland river of Sirvan River in Kordastan province) were studied using 12 rainfall storm accurred during Nov. 2003 to April. 2004 and a linear time disc rated model. Curves showing the time variations of observed sediment load were compared with the model simulated curves using the relative errors and square errors indices. Results show that the developed model could be able to predict suspended sediment load time variation for a given rainfall event using the parameters of one hour last sediment yield, one hour last rainfall intensity, and two hour last rainfall intensity. Correlation coefficient of this relation was estimated as 95%.
