Abstract:

In this study HEC-RAS model was used for the hydraulic analysis of the Nagpur minor canal irrigation system. Hydraulic models are the basic tools for understanding the hydraulic flow behaviours of open channels. Manning’s roughness is very sensitive parameters in development of the hydraulic models. It is necessary to calibrate the Manning’s coefficient (“n”) values. HEC-RAS Model was used for calibrated and validated the sets of observed water depth and simulated water depth. The model was run with different values of ‘n’ between 0.016 and 0.033 and the calibrated Manning’s n value was obtained as 0.0165. Model performance has been tested using the six statistical criteria These are Nash-Sutcliffe efficiency (NSE), root mean squared error (RMSE), normalized root mean squared error (N RMSE), correlation coefficient (r) mean absolute error (MAE) and standard error of estimate (SEE), There has been relatively superior calibration and validation of model was observed at all five locations.
