Abstract
Possibilities of Artificial Groundwater recharge in the
Azraq Basin: Potential Surface Water Utilization of Five representative
Catchment Areas (Jordan).
Atef Al-Kharabsheh
Abstract: The goal of the present study is the investigation of new
surface water resources for groundwater recharge in the Azraq basin. Five
catchment areas were selected as being suitable for the construction of
recharge dams, two are located in the western part (El Maghayer and Butum)
and three in the northern part (Kleita, Erratam and Aritain) where major
flood quantities might be received. The average total flood amounts received
by the catchment areas are calculated to be about 8.5 MCM every year.
These quantities are equal or more than discharge of the dried up springs
in the Azraq basin, which indicates that the springs will again be productive
as soon as the dams are constructed. The natural materials in the field
will help in constructing low - cost recharge dams. The water needs about
190 - 460 days to infiltrate naturally to the groundwater. The elevation
area capacity of the reservoirs show that the dams will accommodate all
flood quantities.
The hydrochemical investigations indicate that the flood waters will have
no negative environmental impact on the groundwater. A geochemical mixing
model with different ratios shows that the groundwater will be positively
affected by the recharge of the floods. Evaporation model of the flood
waters using different ratios to reach 40 % shows that the high quality
of the water will be assured.
