Hydrologic modelling for runoff determination
The quantitative assessment of runoff from a catchment is necessitated when a structure in the vicinity of a watercourse has to be designed. In the present study the USDA Soil Conservation Service runoff curve numbers, modified for Indian conditions, are established for the Kaliaghai river basin from a digitized land-use or land-cover map derived from IRS-IA LISS-II data. The software 'HYDMOD' was developed to translate the curve number into volume of runoff. The linear regression model was developed to correlate the observed and estimated runoff. Average percentage deviation between the observed and estimated runoff was found to be in the order of 5.9.
