ANALYSIS OF SURFACE RUNOFF FROM BALTIRA RIVER BASIN USING SCS-CN AND GIS

Abstract
Abstract - As it entails the vital duties of planning and managing available water resources, watershed management is crucial in the subject of water resources engineering. Both geographical and non-spatial data can be managed using remote sensing (RS) and geographic information system (GIS) techniques in order to manage a watershed's hydrologic features successfully. These methods were applied specifically in the Baltira watershed, which is a part of the Krishna River Basin in the Sangali District of Maharashtra. An extensive study was carried out to examine the daily rainfall and forecast the corresponding daily flow within the watershed using data from seven raingauge stations, covering from 1998 to 2020. This forecast was created using the Soil Conservation Service - Curve Number (SCS-CN) technique and GIS technologies. The average annual rainfall from 1998 to 2020 varied from 233 millimetres at the least to 945.45 mm at the maximum. Understanding the watershed's characteristics and runoff patterns was achieved through the development and using a rainfall-runoff model.This study emphasizes the effectiveness of RS and GIS approaches in managing and analysing hydrological data within the Baltira watershed and other similar locations, and also highlights the significance of watershed management in water resources engineering.
