Evaluating and modeling of volume of loaded sediment is one of the most important subjects

in water resources management. Investigation of experimental relations and mathematical

equations shows that yet analytical or suitable experimental method has not presented

for the estimation of suspended load carried by a river. For the mentioned reason, in the

current study we use contemporary data of water discharge and sediment discharge of

Glinak Station located on Taleghan River for modeling of daily suspended load by using

Fuzzy method and regression model. We assess results of these two models by using statistical

parameters like RMSE, MAE, and R2. Results show that Fuzzy method (RMSE=51.3,

MAE=31.16, R2=0.9604) has more accuracy than regression model (RMSE=93.3,

MAE=52.85.R2=0.81) to assess daily suspended load.
