Lecture 42: Groundwater Exploration 4

This lecture extends the previous discussion by illustrating the concept of the benefited/submerged area ratio for various reservoirs, providing a schematic representation and a table of these ratios. The data highlights that reservoirs like Chanderi and Jakhaura have high benefited/submerged ratios, indicating efficient water storage versus area submerged. The lecture also showcases the use of remote sensing and GIS techniques, particularly Landsat images and SRTM DEM, for mapping quartz reefs and identifying potential dam sites in the Bundelkhand Craton, a region with high runoff yet acute water scarcity. Detailed methodologies, including dam simulation and land-use mapping, are employed to optimize dam parameters and enhance water resource utilization. Field observations further validate these findings, underscoring the importance of integrated approaches in groundwater exploration.
