SURFACE RUNOFF EVALUATION FOR AGRANI RIVER BASIN USING GEOSPATIAL TECHNIQUES

Nowadaysin water resources engineering watershed managementplays a vital role.Water harvesting structure based on management of water resources is essential to plan and protect the existingresources. Geographic Information System (GIS) and Remote Sensing (RS) techniques are mostly useful to achieve spatial and non-spatial database that signify the hydrologicfeatures of the watershed use as accuratelyas possible. In this study area of Agrani river basin, Upper Krishna basin, Western Maharashtra, India. The yearly rainfalldata of 7rain gauge stations (1998 –2015) together used to calculate the yearly runofffrom the watershed using Soil ConservationService –Curve Number (SCS –CN) method and Arc GIS tool. From the collected annually rainfall data for the years of 1998 to 2015 in the study area annualrunoff hasbeen calculated.The average rainfall is 466.63 mmrespectively and typical runoff for the year of 1998 to 2015 is 20.75 mm3 respectively
