ANN-Based Approach for Predicting Rating Curve of an Indian River

الملخص EN

Prediction of stage-discharge relation or a rating curve is of immense importance for reliable planning, design, and management of most of the water resources projects.

Measurement of discharge in a river is a time-consuming, expensive, and difficult process, and the conventional approach of regression analysis of stage-discharge relation does not provide encouraging results especially during the floods.

Therefore, the present study is aimed at the application of soft computing techniques such as back propagation feed forward neural network-based algorithm for modelling stage-discharge relation.

A data set of discharge-measuring station located on an Indian river has been used for analysis in the present study.

A multilinear regression model was also employed on the same data in order to compare the performance of the results.

The performance of each model has been compared by calculating correlation coefficient and root mean square error for the used data set.

The outcome of the study suggests that the back propagation feed forward ANN works quite well for the data sets and produced promising results in comparison to the linear regression technique.
