👉 Watershed math, also known as the watershed or basin analysis, is a method used to understand and model the flow of water across a landscape. It involves identifying the boundaries, or watersheds, that divide a drainage basin into distinct areas where water drains into different rivers or lakes. By analyzing elevation data, such as from a Digital Elevation Model (DEM), watershed math helps determine the flow direction and accumulation of water, predicting how water will move through the terrain. This technique is crucial for hydrological studies, environmental management, and urban planning, as it aids in assessing flood risks, managing water resources, and understanding the impact of land use changes on water flow.
