Batha River
The Batha River is an ephemeral river in Chad. As with any rivers or lakes in this region, its existence depends on the amount of rainfall. The river's delta is at Lake Fitri in Chad. Batha River carries water west from Ouaddaï highlands Ouaddaï Highlands is an area in east of Chad along the border with Sudan. The Ennedi Plateau and the Ouaddaï highlands in the east of Chad complete the image of a gradually sloping basin, which descends towards Lake Chad. There are also central ... during rainy seasons, usually during flash flooding. References Rivers of Chad {{Chad-river-stub ...

Chad
Chad (; ar, تشاد , ; french: Tchad, ), officially the Republic of Chad, '; ) is a landlocked country at the crossroads of North and Central Africa. It is bordered by Libya to the north, Sudan to the east, the Central African Republic to the south, Cameroon to the southwest, Nigeria to the southwest (at Lake Chad), and Niger to the west. Chad has a population of 16 million, of which 1.6 million live in the capital and largest city of N'Djamena. Chad has several regions: a desert zone in the north, an arid Sahelian belt in the centre and a more fertile Sudanian Savanna zone in the south. Lake Chad, after which the country is named, is the second-largest wetland in Africa. Chad's official languages are Arabic and French. It is home to over 200 different ethnic and linguistic groups. Islam (55.1%) and Christianity (41.1%) are the main religions practiced in Chad. Beginning in the 7th millennium BC, human populations moved into the Chadian basin in great numbe ...

Ephemeral River
A stream is a continuous body of surface water flowing within the bed and banks of a channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long large streams are usually called rivers, while smaller, less voluminous and more intermittent streams are known as streamlets, brooks or creeks. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighted subterranean water, and surfaced groundwater (spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes that respond to geological, geomorphological, hydrological and biotic controls. Streams are important as conduits in the water cycle, instruments in groundwater ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Fitri
Lake Fitri is located in the center of Chad about 300 km east of N’Djamena. The normal size of the lake is about . The size of this lake can triple in wetter years. This freshwater lake is shallow and is fed by seasonal rainfall and run-off from a catchment area estimated at . The principal river feed is the seasonal Batha River which carries water from the Ouaddai massif to the west. Similarly to Chad's other lake, Lake Chad, it is not quite as large as it once was. It has been designated under the Ramsar Convention as a Wetland of International Importance. The normally permanent lake may dry out during severe drought A drought is defined as drier than normal conditions.Douville, H., K. Raghavan, J. Renwick, R.P. Allan, P.A. Arias, M. Barlow, R.

Ouaddaï Highlands
Ouaddaï Highlands is an area in east of Chad along the border with Sudan. The Ennedi Plateau and the Ouaddaï highlands in the east of Chad complete the image of a gradually sloping basin, which descends towards Lake Chad. There are also central highlands in the Guera region rising to . Water systems Batha River is an important ephemeral river that carries water west from these highlands during rainy seasons, usually during flash flooding. The land Ouaddaï highlands mark Chad's eastern border and also divide the Chad and Nile watersheds. These highland areas are part of the East Saharan montane xeric woodlands ecoregion. Yellow Nile The Yellow Nile is a former tributary that connected the Ouaddaï highlands of eastern Chad to the Nile River Valley ca. 8000 to ca. 1000 BCE.Keding, B (2000).
