List Of Drainage Basins Of South Africa
A drainage basin is an extent of land where water from rain and melting snow or ice drains downhill into a body of water, such as a river, lake, reservoir, estuary, wetland, sea or ocean. The drainage basin includes both the streams and rivers that convey the water as well as the land surfaces from which water drains into those channels, and is separated from adjacent basins by a drainage divide. The drainage basin acts like a funnel, collecting all the water within the area covered by the basin and channelling it into a waterway. 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. The drainage basins in South Africa do not correspond with the Water Management Areas, and have the letters A, B, C, D, E, F, G, H, J ...

Rietvlei River
The Rietvlei River is a small river in central Gauteng Province, South Africa. It feeds the wetlands of the Rietvlei Nature Reserve, before it flows into Rietvlei Dam, which is one of the main sources of water for Pretoria. The river downstream of the dam is known as Sesmylspruit, which is a tributary of the Hennops River and part of the Crocodile River (Limpopo) , native_name_lang = , name_other = , name_etymology = , image = Krokodilrivier, a, Phalandingwe.jpg , image_size = , image_caption = Crocodile River at Pelindaba, North West , map ... basin.

Mokolo River
The Mokolo River is a major watercourse in Limpopo Province of South Africa. This river collects much of the drainage of the Waterberg Massif and discharges it to the Limpopo River. The river's catchment area comprises . Course The Mokolo River and its upper course tributaries rise in the southwestern part of the Waterberg, between 1200 and 1600 metres above mean sea level. The Mokolo proper originates about 1.5 km north of Alma, Limpopo, Alma at the confluence of the Sand River (Mokolo), Sand River with the Grootspruit River in a flattish, open area with numerous koppies. Shortly thereafter it flows northwards through a steep gorge emerging above the town of Vaalwater. As it heads northwards it threads through the northern Waterberg, an extensive rock formation that was shaped by hundreds of millions of years of river erosion to yield diverse bluffs and buttes.

Drainage Basin A4
Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess of water. The internal drainage of most agricultural soils is good enough to prevent severe waterlogging (anaerobic conditions that harm root growth), but many soils need artificial drainage to improve production or to manage water supplies. History Early history The Indus Valley civilization had sewerage and drainage systems. All houses in the major cities of Harappa and Mohenjo-daro had access to water and drainage facilities. Waste water was directed to covered gravity sewers, which lined the major streets. 18th and 19th century The invention of hollow-pipe drainage is credited to Sir Hugh Dalrymple, who died in 1753. Current practices Geotextiles New storm water drainage systems incorporate geotextile filters that retain and prevent fine grains of soil from passing into and clogging the drain. Geotextiles are synthetic textile fabrics specially manu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
