Sabkhas is special Geomorphological Feature that characterize the low-lying coasts and lower internal land where the water table is very near to the ground; Therefore they appear in many sectors of the Northern Nile Delta area where consider the ideal area for the study of Sabkhas for many reason. The first reason represent in the length of its coastline that overlooking in the Mediterranean sea and the second reason represent in the flat and low of Topographic surface, in addition to the overlapping between seawater and northern Nile delta area that appear in Coastal lagoons and the overlapping between land and Mediterranean sea where this is evidenced by three headland penetrating in to the sea.
The Northern Nile Delta Area represent an important developmental Region due to It’s location among the three Important urban and economic Region in the Arabic Republic of Egypt. The first region Alexandria Governorate in the west and the second region Port Said Governorate, in addition to North Sinai in the east. This two Region together represents the main commercial Egypt’s outlets on the Mediterranean sea, in addition to The Middle of the Nile Delta Region, which represent an important agricultural and economic Region moreover this area is characterized by over population, so it represents a strategic bridge connects the economic zones, so that Many Studies specially Geographic Study put the northern nile Delta area on target where it’s important to study the components of the natural environment.
The study was carried out on the sabkhas at the Northern Nile Delta in many Elements. At first this study investigates the Geographical distribution of Sabkha and its development and their Geomorphologic characteristics by identify Its locations depending on many various maps, satellite image analysis and interpretation and Surveying Field operations, in addition to studying the factors affecting in the formation and development of sabkhas then the study reviewed the result of Sabkhas deposits analysis .The study Focuses on geomorphologic features that appear on their surfaces and features that surround it where Affect them and affected by it In addition to Sabkhas classification and change of them. Finally Knowing how to take advantage of the Sabkhas and get to know most important ingredient and natural obstacles for economic development in Northern Nile Delta Region and what is the best use of these ingredients and how to overcome the obstacles Or avoid them through lay the foundations for regional and economic planning operations through the study of a natural phenomena occupy a large part of the study area.
