3. Results and Discussion:
3.1. Aerial Photo-Interpretation Field Observation Studies:
Erian, Wadid
The most important element used and played the decisive role in the photo-interpretation of the
studied area were the relief and the gray tone elements. The combination of the geomorphic approach as a
hierarchic classification system of geo-forms using the existing body of knowledge in geo-morphology,
with the photo interpretation map and field observations improved the results. The total area and percentage
of each physiographic mapping unit is shown in Table (2), and the physiographic map is presented in Map
(2). The location of the observation points is presented in Map (3).
