MORPHOLOGICAL AND GEOLOGICAL CLASSIFICATION OF THE EGYPTIAN NORTHERN COASTAI ENVIRONMENT USING SPACE IMAGE TECHNOLOGY

Atia, Nora 


Abstract


ABSTRACT The coastal environment is the area lying at the interface between the land and the sea. The Egyptian northern coast has nearly E-W trend, and extends from Rafah at the east to Al Sallum at the west for about 1000 km, its wide ranges from meters to kilometers. Tectonically, this coast is classified as a mature passive margin coast. The structural features and lithologic units controlled this coast, and shaped its shore lines. The Egyptian northern coast is complex in types of landforms, structural features, and geologic unites, it is composed of a wide range of landforms including; recent and old beaches, sand bars, spits, sand dunes, lagoons, wet salty clay lands, swaps, headlines, bays, delta, and cliffs. The space images give a synoptic view and regional perspective of the all coast and its Landforms. The MODIS, LANDSAT, SPOT and Astronomies photographs images of different spatial resolution were used as a tool for study the relationships among the coastal features, and the spatial distribution of the different types of the coast landforms. Moreover, the Landsat and Spot images of the shortest electromagnetic wave have been used to observe the shallower part of the offshore zone as well as the breaker zone. According to visual interpretation and measurements of the coastal landform units, structural features, and geologic unites from the used space images and filled observation, the Egyptian northern coast has been locally classified into three coasts, they are: the eastern (sandy) coast, the central or Delta (muddy) coast, and the western (rocky) coast. Each one of these coasts possesses specific beach shape, lithologic units, structural features and coastal landform types. The development in each of these coasts is highly affected with the size, type and location of the various coastal landforms.
