Abstract
The study area is a part of Wadi Qena in the Egyptian Eastern
Desert. This area lies between the 26

.65, 26

.75 latitudes (N) and 32

ο
.9 longitudes (E) and the area about 204 km
2
. The area under
investigation located between the Nile Valley from the West and the Red
Sea mountains from the East.
The climatic conditions of Wadi Qina area as those characterizing
the Desert areas of Egypt. It is characterized by a hot rainless summer and
mild in winter.
Essentially, this research investigated new reclaimed areas in the
Egyptian Eastern Desert region aiming at assessing land recourses based
on remote sensing and GIS techniques.
The Landsat 7 satellite imagery was enhanced (Subsetting and
Rectification) to get reliable information. The valuable information of the
new reclaimed areas using remote sensing and GIS techniques could
provide decision makers, land managers and farmers themselves with
some information needed to improve land quality guiding them to what
crops are most suitable for their land characteristics.
Digital Elevation Model (DEM) was produced from SRTM image
to identify spot heights and elevation necessary for identify the
geomorphologic units. Landsat 7.0 image was draped over DEM to get
Six physiographic units i.e., Wadifloor (WF) with an area of 61.82 Km

- Soil characteristics could be summarized as follows:
1 – Wadifloor (WF):
These soils occurred on almost flat areas occupying an area of
61.82 Km
2
and representing 30.24% of the total areas. Soil texture is
loamy sand. Electrical conductivity (EC) values are ranged between
moderate and high. pH values are light alkaline. Calcium carbonate
values are very high. ESP values are moderate. Organic matter content is
low. CEC values are low. Available macro and micronutrients values are
low. Soil taxonomy of this mapping unit is Typic Haplocalcids.
