Water Resources Management Using Modeling Tools in Desert Regions: The Azraq Basin, Jordan

This research is aim to investigate holistic management of floodwaters in Jordan to better understand how this natural hazard can instead be viewed as a valuable natural resource. The groundwater resources in the study area are depleted by the domestic usage and irrigation uses. 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. HEC-HMS model were used in order to estimate the surface runoff. A groundwater model for the study area was used to evaluate the effect of flood water on groundwater recharge using the existing volcanic cave. The result shows that Beer Al-Hamam cave with a volume of 20,000 m 3 , when used to store flood water and recharge it for groundwater. The groundwater table will rise (localy) in the range of 0.2 to .5 m per year.
