Water reservoir techniques using remote sensing and GIS: a literature survey

Abstract The issue of storing flood waters caused by rains and river floods is very important to address the problems of drought. This study reviewed the latest research to address the problems of water scarcity and conservation with advanced methods. these study methodologies range from employing Geographic Information Systems Programs to handle and analyses remote sensing data to incorporating contemporary techniques to enhance morphometric analysis, where researchers employed various analytical techniques. To determine if these watersheds are appropriate for storing water, some studies have preferred Multi-Criteria Decision-Making models (MCDM), more especially the fuzzy analytical hierarchy (FAHP) Fuzzy Analytical Hierarchy Process. Others have employed techniques for hydrological analysis, such as the ArcGIS program’s Arc hydrology tools. Researchers reached a consensus regarding the fundamental parameters required for morphometric analysis in the demarcation of watersheds, notwithstanding methodological variances. Additionally, many researchers have argued the importance of using the Shuttle Radar Topography Mission Digital Elevation Model (SRTM-DEM) mission and the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER DEM) in morphometric and hydrologic studies.
