River basin

"The area of land from which all surface run-off flows through a sequence of streams, rivers and, possibly, lakes into the sea at a single river mouth, estuary or delta." (European Environmental Agency, 2019).

"Both river basins and watersheds are areas of land that drain to a particular water body, such as a lake, stream, river or estuary. In a river basin, all the water drains to a large river. The term watershed is used to describe a smaller area of land that drains to a smaller stream, lake or wetland. There are many smaller watersheds within a river basin"(Milwaukeeriverkeeper, n.d.).

ARSET - Using Earth Observations to Monitor Water Budgets for River Basin Management II

Overview:

Rivers are a major source of freshwater. They support aquatic and terrestrial ecosystems, provide transportation, generate hydropower, and when treated, provide drinking and agricultural water. Estimating and monitoring water budgets within a river basin is required for sustainable management of water resources and flooding within watersheds. This webinar series will focus on the use of NASA Earth observations and Earth system-modelled data for estimating water budgets in river basins.

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.

Rivers are a major source of freshwater. They support aquatic and terrestrial ecosystems, provide transportation, and generate hydropower. Managing river basin watersheds is critical for developing policies for sustainable water allocation and development. Over the online course of four sessions, this introductory webinar series will address using satellite data and Earth system modelling data sources to estimate surface water budgets
