Runoff simulation models were developed to predict runoff for basin of West Godavari district, Andhra Pradesh by utilizing adaptive neuro-fuzzy inference system (ANFIS).Combinations of variables like previous three day stage, previous two day stage, previous one day stage, previous three day run off, previous two day run off, previous one day runoff as input and present day runoff as output were explored. The performance of different ANFIS based models during training and testing periods were evaluated through correlation coefficient (r), coefficient of efficiency (CE) and root mean square error (RMSE). Results of different combination of input per membership function (MFs) were compared and it was depicted that ANFIS model with three MFs per input is having reasonable accuracy for triangular membership function with the values of r (0.991), CE (99.1%) and RMSE (529.93 m3/s). ANFIS model with three MFs per input performed best among trapezoidal member function applied with r, CE and RMS E values 0.993, 99.0% and 468.40 m3/s, respectively. ANFIS model with generalized bell membership function and one MF per input was selected as the best performing model with r (0.947), CE (96.8%) and RMSE (1265.56 m3/s). Trapezoidal, 3 is the best simulation model among all ANFIS model.
