Watershed Delineation in QGIS/ Hydrological Analysis

Hydrologic analysis using QGIS involves the use of QGIS software to study the distribution and movement of water on the earth's surface. QGIS provides tools for processing and visualizing hydrological data, such as watershed delineation, flow accumulation, and flood risk mapping. By utilizing QGIS, hydrologists can analyze and model the behavior of water within a specific geographic area, allowing for the identification of potential water resource management issues and the development of effective solutions. The software's capabilities enable the integration of various data sources, such as satellite imagery, digital elevation models, and climate data, to support comprehensive hydrological analysis.
