الملخص EN

Environmental Studies is a multidisciplinary academic field which systematically studies human interaction with the environment in the interests of solving complex problems.

Environmental Studies brings together the principles of Sciences, Commerce/ Economics and Social Sciences so as to solve contemporary environmental problems.

El-Dakhla depression has available with natural ingredients necessary for agriculture, including the soil reclamation, which has an area of about 1.2 million acres, as well as groundwater which has a daily discharge of about 945 million m3.

The main aim of current research was to study a agro-ecosystem components of the drainage pools and the related exchange networks , through the environmental assessment.

To achieve this aim; the current study has depanded on remote sensing GIS techniques, in addtion to topographic maps analysis during different time periods and field studies.

The study concluded that agricultural drainage main pools represented in two ranges basic principles: the first in the middle range of the depression, and the second in the western.

The study recommends the need to develop agricultural drainage in the depression under environmental control, and through the work of periodic reports by taking into account the economic advantage of the drainage pools, as well as protecting nearby deterioration of agricultural soil due to leaching processes and salinization.
