AN INNOVATIVE APPROACH FOR ESTIMATION AND EVALUATION OF SPATIALLY DISTREIBUTED HYDROLOGICAL PARAMETERS WITH TEMPORAL RESOLUTION OF LAND USE-LAND COVER CLASSES USING REMOTE SENSING & GIS BASED ‘RINSPE’ MODEL
Abstract
The estimation of Hydrological parameters of a catchment is an important aspect in engineering planning,
environmental impact assessment, flood forecasting and water balance calculations. There have been efforts to
estimate, analysis and evaluate the Hydrological parameters to make stable water use and other Hydrological
problems to solve. This study focuses on the rainfall-runoff and infiltration estimation and evaluation of
results by considering temporal resolution of Land use-Land cover classes using’Runoff-Infiltartion and nonPoint
Source Pollution Estimation’ (RINSPE) model. To proceed this study through the ArcView selecting
study area and collecting data, basically, are needed. This study chosen karha basin which is a sub-basin of
Bhima basin and gathered various raster and feature class data. These collected data were used in
preprocessing in the ArcGIS 9.3 for computing Hydrologic parameters. As input data for the rainfall-runoff
model, this study selected the total 8 number of gauge stations. To reflect spatial rainfall characteristics of
precipitation data of specific hydrologic events IDW method was used. Finally, RINSPE Model run in which
SCS-CN method adopted for calculating runoff. The model run in two differ scenarios by considering temporal
resolution of 10 years (2004-2013) for land use-land cover maps. The estimated runoff depths and infiltration
were 268.63 mm, 281.02 mm and 315.65 mm, 316.88 mm from two differ years of 2004-05 and 2013-14 Land
Use-Land Cover maps
