Modeling of Groundwater Recharge by Rainwater Harvesting-Wadi Bayer  

Wadi Bayer is one of Jordan's desertic areas with very low precipitation and limited water resources. It is a
typical example of the Jordanian water scarcity chronic condition. Groundwater recharging strategy is one of the
long-term solutions of such water scarcity problem due to harsh climatic conditions and high evaporation rate.
The groundwater resources in the area are utilized by the Bedoins for their domestic and cattles' uses. The
groundwater is abstracted through three shallow wells drilled in the course of Wadi Bayer. The limited
amount of the groundwater in the area is attributed to the limited natural recharge through the wadi bed
during the occurrence of floods.
In this study, a location of recharging dike was proposed at a distance of 150-200 m to the south-west of the
existing wells, its reservoir area was estimated by 0.0285% of the catchment area of Wadi Bayer, which
reflects the rare runoff occurrence
