Rainfall runoff modelling using adaptive neuro fuzzy inference system has been presented. In the present study ANFIS models are developed using different membership functions Triangular, Trapezoidal, Bell-shaped, Sigmoid and Gaussian method. All the models are compared with the statistical tests. West flowing river Nethravathi located in Karnataka, India has been selected as study area. It was observed that adaptive neuro fuzzy inference system using Triangular membership function show a good performance compared to other models developed
