1.8. Coast changes due to sea level increase Samur-Sumgayit coast. On the area from Samur river to Mukhtadir set. The penetration of sea water masses is not significant due to development of high shore terrace. But generally it increases in the south-eastern direction from the first meters to the first tens meters. After Mukhtadir set. till Agzibirchala lagoon the shores backward is 100-300 m, further southward up to Sumgayit town the penetration depth reduces to 100-50 m. Apsheron peninsula. Morphology of the rear part of beaches of the peninsula northern coast eastward from Sumgayit town blocks for deep penetration of water masses which is limited by the first tens meters, and on the separate areas it doesn't exceed 5-10 m or absent at all (like on rocky coast of Amburan cape). Southward the peninsula coast is characterized by little sea approach (20-50 m), and in zone of Sultan cape there is an active swamping of territory. Directly on territory of Baku city apart of seaside boulevard, as well as port constructions, territory of industrial enterprises and oil-gas producing boards, communications are undergone by flooding. Shirvan section takes coastal line of Gobustan and South-East Shirvan. Here the backward of coastal line is from 50 to 100 m on separate parts. Kura-Gizilagach section. 4000 ha of coast is flooded in Kura delta. Southward on Neftchala area the sea had moved into the land for 500-2000 m and flooded over 15000 ha of ground. Kura spit is nearly under the water now except a small southern part. It is an island now. More lifted part with width 500 m had remained from large island of Sara with all adjacent small islands. The water movement in Gizilagach gulf reached 8-10 m. Lenkaran-Astara coast is characterized by amplitude reduction of shore backward from 500-2000 m on the north up to 200-500 m on the south. Besides the flooding of narrow coastal line the abrasion development of various intensity during the first 50 years is typical for this area as well. Here the yearly volume of washing out is 300 thous. m3/year. The modern area of flooded grounds is 3170 ha. |
