هيدرولوجية المياه الجوفية في حوض الحسا : دراسة جغرافية تحليلية

الملخص EN

This study tackles the subject of groundwater hydrology in Al-Hassa Basin.

It aims to demonstrate the impact of natural conditions of the basin on the quantity of its water, and to analyze the hydro geological characteristics of the units that make up the basin, namely: Amman –Wadi Al-Seer unit (B2 – A7), lower Ajloun unit (A1–7), and Um Rjam units (B4), in addition to assessing the water balance of the basin during the period from 2000 to 2007.

To achieve these objectives, the study adopted a descriptively analytical approach, this approach may be represented in the following points.

- The description of the natural data of the basin and analysis of their impact on the groundwater storage.

- Analysis of the characteristics hydro geological of units of the basin.

- Assessing the elements of the water balance in the basin.

The main results that the study : Stepwise regression analysis shows the importance of natural variables in interpreting the disparity of the size of the annual feeding of water layers in AL-Hassa basin.

The natural variables were (62%) of the total disparity in the size of the annual feeding of water layers in that basin.

The variable of the amount of rainfall was the highest : the interpretation of this variable was (28%) with a statistical relevance (0.001) .

The water level in the reservoir is affected by the annual averages supply of water layers.

The general tendency of these averages indicates a progressive decrease, as the annual averages range between(12.7–19.1mm3).

In addition, the results of the study indicate the presence of clear excessive consumption of the groundwater shortage in the basin, as the shortage in the balance of groundwater in the basin is about (5.7mm3).
