A Study on Geomorphological Response for Runoff Prediction in Small Watershed
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 4
Abstract
Abstract: Hydrological data of Arki sub-watershed comprising an area of 2460 hectares of a hilly catchment of Upper River Gambhar, located in mid hills of Solan district of Himachal Pradesh were analyzed to study the geomorphological response for estimation of direct runoff by using GIUH model. GIUH model was based on storm basis incorporating geomorphological parameters with the hydrological characteristics of the watershed. Geomorphological parameters were derived from topographic maps of the watershed satisfying Horton’s1(1945) law when ordered according to Strahler2(1957) ordering procedure. The GIUH of the watershed was calibrated using the observed direct runoff hydrograph data. Direct runoff hydrographs were obtained from GIUH and these were compared with the observed DRHs to judge the performance of the model. The model performed well for all the test data sets with high coefficient of efficiency, lower relative squared error and absolute relative error in computed peak flow rates values and near zero Coefficients of Residual Mass values. The percentage absolute error in time to peak between computed and observed direct runoff hydrograph was found to be zero percent. The performance of the model showed that it simulates components of direct runoff of hydrographs well.
