■hbmHHHHBi 626 STUDY APPROACH AND TECHNIQUES The main task of the present work is the int erpretation of the landforms in the area of interest and their hydrogeologic bearings. The control upon water flow either on the surface or in the subsurface and the impacts upon gr oundwater conditions in the Miocene aquifer are the objects. The study approach depends on both the qua litative and quantitative techniques either in the lab or in the field. Among these tech niques are; 1. Stereoscopic examination of 249 aerial photographs of scale 1:40,000, 2. Assembling the photo-mosaics covered the area (about 13 photo-mosaics of scale 1:50000) 3. Assembling the landsat imageries which include the area of interest. Three of the ERTS imageries of bands 5>6,and 7 are select ed to represent the conditions of January and June of the year 1976, 4. Infiltration tests by using double rings in selected sites representing the different surface deposites, 5. Sampling of rock, soil, and water bodi es. The collected samples are studied petro- graphically or chemicaly, 6. Field survey and measurements. Distance- angles and levels are obtained, 7. Hand templet and sloted templet methods for map compilation are applied, and 8. Statistical treatment of the collected data either manually or computerized. RESULTS AND DISCUSSION The landforms and their hydrogeologic bearin gs are investigated as based on the photo interpretation of relief criteria and draina ge patterns followed by field check and meas urements. The results are obtained through systematic procedures and discussed in the following categories: 1. Regional features The regional features west of the gulf of Su ez are defined by the landsat imageries. They are defined as based on normal and subtle d- ifferences in color and tones along straight or curved lines,the lineaments in drainage and the alignments of surface features. The following features are defined ( Fig.2 ): 1.1. The regional outline of the Precambri- an sheild,where defined by the contact boun- aries between dark grey and dark white tones. The area of the sheild represents the higher plateau area in the Eastern Desert of Egypt. It slopes in general to the east and the west. 1.2. The shape of the coast line of the gu lf of Suez, where it runs into zigzag line in both sides and trending NW-SE. It is highly controlled by the regional trends of faulting in the gulf region. The N-S and WNW-ESE fault- s play the pioneering role in this manner. 1.3. The regional patterns of drainage ba sins, where they run either to the east or t- he west of the basement sheild. The higher plateau maintains the water divide and the up-stream parts of the drainage basins. 1.4. The local bodies of salt and brackish water on the surface, where they occupy the lowlying areas along the coast. They represen- t the marsh and swamp areas. They are develo ped mainly due to subsurface intrusion of sal- t water from the gulf and seeps from the gro undwater in the land. 1.5. The structural ridges , where they de- *44-. Nf ' kb.

The evaporite exposures along the weste rn coast of the gulf, where they occupy the areas of whitish tone. They represent the up per unit of Middle Miocene section in the gu lf of Suez region. 2. Drainage and hydrographic patterns When dealing with the drainage and hydrograp hic patterns the photo-mosaics are examined. The drainage basins are delineated and the boundaries are defined. They are defined by the name of the main valley. The drainage pa tterns represent the main channels and tribu taries in each basin or sub-basin. A combine- d map of the area is compiled after the exam ined mosaics (Fig. 3). Almostly, the main channels have a trend from west to east in the area west of the gu lf of Suez. This reflects the influence of the initial slope trend and the structural framework. Certain patterns of drainage are defined qualitatively and quantitatively in the pres ent drainage sub-basins. They are differenti ated into several types as based on some cri teria such as, the degree of integration, the density, the degree of uniformity, the orien tation, the degree of control, the angularit- y, and the angle of juncture ( Ray,I960; Tho rnbury,1962; Howard,1967; and El-Etr & Yousi- f,1978). About 13 of photo-mosaics are examined (No- s.,25, 49» inclusive). Nine sub-basins are defined i actively, outlets g annels is The fol dealing w studied a 2.1. Tb basins va sq. Km. 2.2.
