Nile basin water balance Global distribution of water balance in the soil averaged over the years 1981-2010 from the CHELSA-BIOCLIM+ data set [1]. The law of water balance states that the inflows to any water system or area is equal to its outflows plus change in storage during a time interval.

The Ogallala Aquifer (oh-gə-LAH-lə) is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. As one of the world's largest aquifers, it underlies an area of approximately 174,000 sq mi (450,000 km 2) in portions of eight states (South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas).

The global annual runoff into the oceans (38,500–44,200 km 3 /year) is dominated by runoff into the South Atlantic from eastern South America, into the western Pacific from east Asia, and into the Indian Ocean from India, and southeast Asia.
The main water supplier for the basin is Lake Victoria, located in the Great Rift Valley. [4] About 238 million people live within the Nile basin, 172 million of those inhabit rural localities. [5] In the southwestern part of the basin in South Sudan near the watershed with Congo Basin relief is made up a single large pediplain. [6]
The list of drainage basins by area identifies basins (also known as "catchments" or, in North American usage, "watersheds"), sorted by area, which drain to oceans, mediterranean seas, rivers, lakes and other water bodies. All basins larger than 400,000 km 2 (150,000 sq mi) are included
Watersheds of North America are large drainage basins which drain to separate oceans, seas, gulfs, or endorheic basins. There are six generally recognized hydro-logical continental divides which divide the continent into seven principal drainage basins spanning three oceans ( Arctic , Atlantic and Pacific ) and one endorheic basin.
The Shared Vision Program (SVP), “a Basin-wide program that focuses on building institutions, sharing data and information, providing training and creating avenues for dialogue and region-wide networks needed for joint problem-solving, collaborative development, and developing multi-sector and multi-country programs of investment to develop water resources in a sustainable way.” [1] It is ...
