WebTaking the mean of the optimum Manning’s “n” values estimated for the flood years of 2001 and 2003, as 0.029 for the focus reach, HEC-RAS based model has been used to simulate the flood for year 2006. It is found from the simulation that Manning’s “n” value of 0.029 yields the maximum Nash and Sutcliffe efficiency of 92.39.
