Each drainage basin is separated topographically from adjacent basins by a geographical barrier such as a ridge, hill or mountain, which is known as a water divide. Other terms that are used to describe a drainage basin are catchment, catchment area, catchment basin, drainage area, river basin, water basin and watershed.
Some suggested and ongoing efforts to achieve this include an emphasis on infrastructural implementations and improvements of wells, rainwater catchment systems, and clean-water storage tanks. Efforts made by the United Nations in compliance with the Millennium Development Goals have targeted water scarcity not just for Africa, but globally ...
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.
The surrounding topography of a catchment zone influences the flow vectors and direction that the water flows. [1] Water flows from areas of high potential energy to low potential energy under the influence of gravity. The geometry of the slope leading to the catchment area influences the amount of water the catchment will contain. [1]
In periods of very high water in the Okavango, the water flows eastward towards the Cuando-Linyanti-System. The last time this happened was in August 2009 after 30 years of falling dry. In times of high water in the Kwando, the water can flow west from the Cuando towards the Okavango Delta, but often evaporates before it reaches the delta. [5]
The river's name is derived from the local community's language, and means river of brown or muddy water. Downstream, the intermittent stream in Somalia is also called Lagh Dera. The upper basin of the Ewaso Ng'iro River is 15,200-square-kilometre (5,900 sq mi). [2] The river has a continuous water supply due to the glaciers on Mount Kenya.
The transport of pipe segments for the Great Man-Made River (GMMR) in the Sahara desert, Libya, during the 1980s.A network of pipes that supplies water from the Nubian Sandstone Aquifer System, a fossil aquifer in the Sahara desert of Libya, the GMMR is the world's largest irrigation project.
Inkomati WMA, or Inkomati Water Management Area (coded: 5), [1] in South Africa is situated in the north-eastern part of South Africa in the Mpumalanga Province, with a small area in the Limpopo Province. It borders on Mozambique in the east and on Swaziland in the south-east.
