In water construction projects, river engineering, and irrigation and drainage engineering, it is vital
to estimate the accurate volume of the sediment transported by rivers. As the sediment transport
phenomenon is an immensely complex problem, therefore presenting an appropriate solution for
precise evaluation of the suspended load in rivers is tedious and the mathematical models are not
also accurate enough to be applied. Nowadays application of artificial intelligence systems has been
developed as a novel solution in analysis of water resources problems. In this research, the Adaptive
Neuro-Fuzzy Inference System (ANFIS) and the Artificial Neural Networks (ANNs) models were
utilized to determine suspended sediment rate of Ajichay River. Discharge, sediment load and water
level data were used to prepare the models and obtain sediment rating curves. The statistical period
is also divided into three seasons, namely dry, wet and snow melting. The accuracy of the models
for these periods has been tested. The results showed that ANFIS neuro-fuzzy had better accuracy
for determination of suspend sediment loads in comparison with both the ANNS and the rating
curve.
