الاستهلاك المائي لمشروع (حرية-دغارة)‎

الملخص EN

The research includes the study of water needs for the project (Heraea - Daghara), which is one of the most important projects of irrigation and development ,that includes its both branches : social and economic the reason of the importanc of this project is owing to that it represent an agricultural side in regjon into flood plain which is dry desert climate .

That climate can not be depended on rain-fed agriculture .

In accordance with mentioned above , the project is a base of agriculturl flourishment for that region .

The research interviews water needs for the project , in additio to irrigation efficiency.

That means there is an overall water balance between water amount and wholly water needs .

The research adopted on the analytical method for the study of spatial analysis of the water need in the project .

on the other hand , it adopted on the quantitive approach method in the study of equations and laws and statistical data requested research.

this study has founded out some impotant results ; the prevailing geographical charachteristics (natural and human) of the project are basic striking factor to increase or verify water needs , as well as the impact of traditional irrigation systems that help to increase water wasteage due to nonability of controlling the amount of water losses in the project.
