Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin.It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
Watershed management is the study of the relevant characteristics of a watershed aimed at the sustainable distribution of its resources and the process of creating and implementing plans, programs and projects to sustain and enhance watershed functions that affect the plant, animal, and human communities within the watershed boundary.

The FBISE was established under the FBISE Act 1975. [2] It is an autonomous body of working under the Ministry of Federal Education and Professional Training. [3] The official website of FBISE was launched on June 7, 2001, and was inaugurated by Mrs. Zobaida Jalal, the Minister for Education [4] The first-ever online result of FBISE was announced on 18 August 2001.

Developing communication that educates science to land managers, policy makers, farmers, and the general public is another important strategy utilized in water conservation. [11] Communication of the science of how water systems work is an important aspect when creating a management plan to conserve that system and is often used for ensuring ...
GIS revolutionized curation, manipulation, and input for complex computational hydrologic models [2] [3] For surface water modeling, digital elevation model are often layered with hydrographic data in order to determine the boundaries of a watershed. [4] Understanding these boundaries is integral to understanding where precipitation runoff will ...
The amount of water in a stream is measured as discharge (volume per unit time). As water flows downstream, streams and rivers most often gain water volume, so at base flow (i.e., no storm input), smaller headwater streams have very low discharge, while larger rivers have much higher discharge. The "flow regime" of a river or stream includes ...
Drainage basins are important in ecology. As water flows over the ground and along rivers it can pick up nutrients, sediment, and pollutants. With the water, they are transported towards the outlet of the basin, and can affect the ecological processes along the way as well as in the receiving water body.
Alameda Creek (Spanish: Arroyo de la Alameda) is a large perennial stream in the San Francisco Bay Area.The creek runs for 45 miles (72 km) from a lake northeast of Packard Ridge to the eastern shore of San Francisco Bay by way of Niles Canyon and a flood control channel.
