A REVIEW ON: INTEGRATED WATERSHED MANAGEMENT USING REMOTE SENSING AND GIS

Abstract

A watershed is a geographical area with a well-defined boundary that collects and drains rainwater into a single outlet. Within its borders, a watershed includes a range of natural resources, including soil, water, and biomass. For the planning and management of land and water resources at watersheds area, watershed models supported by remote sensing data and a geographic information system (GIS) have proven to be essential research tools. Understanding how human and natural events interact and relate to one another is crucial. With reference to the evaluation of watershed management and land use land cover, remote sensing and geographic information, systems (GIS) can yield reliable data. In this review, paper shows the study of watershed development and land changes. A geographic information system is one that is made to collect, store, and process, evaluate, organize, and display any kind of geographic data. The aim of this research is to study issues related to watershed management and LULC. Morphometric analysis using RS and GIS has been very beneficial for the exploration and management of the watershed and it can handle hydrological problems, such as soil erosion, drought, and floods.
