Abstract
Egypt is about one million square kilometer, with its cultivated lands being concentrated around the river Nile valley occupying about 4 % of the whole area with the desert land occupying the rest of Egypt. Mainly because of the scarcity of water, arable land in Egypt was always limited. On the other hand, agricultural production in Egypt is limited by urban encroachment and soil degradation. The excessive population growth and the lack of food security were the guide to expand and extend horizontally the cultivated land. The desert lands in Egypt have much cultivable land for agriculture horizontal expansion. East Oweinat area is one of the most important developmental areas which drawn considerable attention of Egyptian government in the last few decades. The soil and water resources of this area cover the requirements of reclamation projects and implementation of new communities. The ongoing developmental area of East Oweinat is located in the southern part of the Western Desert of Egypt between latitudes 22º 00’ 00’’ - 25º 00’ 00’’N and longitudes 28º 00’ 00’’ - 31º 00’ 00’’E with an area of 95809.46 km2 (958074603.7 hectares) 10.43% of Egypt total area, it is located at about 880 km from Cairo. The present study aims at using Remote Sensing and Geographic Information System technologies in assessing and modeling land and water resources of East Oweinat area in order to help the planners and the decision makers to organize the environmental data, and understanding their spatial association. The present work also aims at determining the soil/water resources potentiality for the purpose of the land potentiality of East Oweinat area by using Designed Land and Water Potentiality Spatial Model (D.L.W.P.S.M.) technique. Determining the developmental potentiality in terms of soil and water is necessary for setting up a management scheme to optimize the use of natural resources of this vital area. Construct D.L.W.P.S.M. to discriminate the soil and water potentiality classes according to definite economical criteria, e.g., soil texture, soil depth, EC, CEC, SAR, O.M, water salinity and water depth.
