Discharge results observed from the experimental channels for smooth and rough surfaces, along with data from a compound
river channel are used in the Genetic Programming. Model equations are derived for estimation of discharge in compound
channel for various types of channel surfaces. Five hydraulic parameters are used for developing the model equations. Models
derived are tested and compared with other soft computing techniques. Evaluations of all the approaches are carried out using five
performance parameters. Finally, the effect of parameters responsible for the flow behaviour is shown through sensitivity analysis.
GP is found to give the most promising results. This work aims to benefit the researchers engaged in modelling of discharge using
machine learning techniques.
