English Abstract
Nyala, capital of South Darfur lies under high pressure due to shortage in drinking water, particularly at the end of dry season.
The main source for drinking water is supply groundwater from Wadi Nyala aquifer.
The aquifer width varies between 200 m (upstream) and 900 m (downstream) with depth variation from 10 m to 20 m.
The total aquifer reserve is 6.2 × 106 m³ stored in gross volume 38.5 × 106 m³ and 3.2 × 106 m² surface areas.
Water pumping occurs from boreholes by submersible pumps and from some dug wells by centrifugal pumps derived with diesel engines.
Some boreholes and dug wells turn dry at the end of dry season due to the rapid drop of water table.The main objective of this study is to look for a good system to pumping water sustainable during the dry season.
First, an overview of water demand for population, such as, domestic uses, irrigation, evaporation, evapotranpiration, and livestock demand is estimated and found to about (9.9679 × 106m³).
Otherwise, the main available resources in the area involving rainfall, and wadi runoff data are estimated from available climate data.
The average of specific yield is estimated as 15 %.
The study concluded that the groundwater resource of Wadi Nyala does not satisfy the growing demand of Nyala town, the expected deficit amounts to about 3.7 × 106m³.
Also, an optimum management strategy is proposed to allow continuous supply from the aquifer during the dry season at rate 22710.6 m³ per day when pumps run 21 hour per day.
Finely, the study recommendations are outlined in order to achieve a proper management of the available resource.
