3. Water Yield:

The map shows the water yield obtained from the water accounting analysis. The water yield

is defined as water that is available after meeting landscape water requirement (landscape
ET). This is the amount of water that can be exploitable for human needs. The map shows

water yield for administrative regions within the basin. Some regions shows negative values,

which indicate that at annual time scales there is not water available. Other regions show

positive values which indicate that at annual time scale, water availability for human needs is

not a problem. Such information is important to understand spatial variability of water
availability within the basin. The blue areas are also called water towers of the basin are the

regions that provide most water to the river and where future activities such as irrigation

development or canals for diverting water can be constructed.

4. Water Availability

Information on water availability in a river basin is crucial for understanding various aspects

of human, environmental, and economic well-being. Through this dashboard, water
