ARSET - River Basin Delineation Based on NASA Digital Elevation Data
Overview:
River basins (known as watersheds in North America) are areas of land that drain precipitation, surface water, and underlying groundwater into a river and its tributaries, eventually reaching a common outlet such as a lake, reservoir, river, or estuary. The drainage pattern is from smaller sub-basin to larger sub-basin, and from higher elevation to lower elevation. Land surface processes, precipitation, storm water, and wastewater runoff within basins have substantial impact on quantity and quality of the water draining into tributaries.
