CONTEMPORARY MORPHODYNAMICS OF THE RIVER CHOROKHI DELTA ON THE BLACK SEA EAST COAST
Abstract
The River Chorokhi delta is located in the southeastern part of the Black Sea, including Batumi city with its coastal part, which today is heavily washed away. Until the 90s of the 20th century, its litho- and morphodynamic peculiarities were mainly conditioned by the solid runoff of the Chorokhi River. Before the construction of dams in Turkey, its volume was 2.5 million m?/per year. In the last 25 years, due to the dams built in Turkey, solid runoff has been catastrophically reduced by 60 times. Also important was the river-sea mouth migration. In the last century, as a result of the construction of a spur on the Batumi cape and the stopping of the alongshore sediment transport, the beach sediment was accumulating in both the above-water and underwater parts of the shore. As a result of upper limit accumulation of material, it is periodically deposited at great depths of the adjacent submarine canyon. There was clearly marked the trend of constant retreat with different rates of entire coastal part of the Chorokhi River delta, towards the land. It is necessary to remove the excess material accumulated near the Batumi Cape and artificially deposit it in other damaged areas as necessary so that the deep submergence of the distal part of the cape provoked by the 1999 earthquake in this area does not happen again. In modern city-building and agricultural activities, the peculiarities of local morphodynamics are often not taken into account. All this, against the background of the rise of the world ocean level, poses a serious threat to the coastal environment. In the conditions of the extreme shortage of solid runoff of the Chorokhi River, in order to preserve the coast, it is necessary to develop methods appropriate to the existing situation.
