Dynamics Of The Deltaic Canyon Area Of The Rv. Chorokhi, Georgia
The Cape of Batumi belongs to accumulative morphological forms and mainly consists of terrigenous sediments of Rv.Chorokhi. It’s location in the central part of the City of Batumi stipulates an importance of intensive research of phenomena. The natural growth of the cape towards the sea was stopped in 30-40-ties of last century, when it’s frontal part closely approached the head of the Rv.Chorokhi submarine canyon. Investigation of the stability conditions of the bottom sedimentary layers deposited inside the canyon has been undertaken on the base of field observations, that repeatedly was held in 1960-2003. Sediment material from Rv.Chorokhi is a main component of the littoral cell of the Adjarian coastline of the Black Sea. The Chorokhi Canyion head locates at depth of 7-8 m at a distance of 70-140 m from the river mouth and invades the area of sediment laden currents. Its frontal area spreads along the shore line for as much as 1,5 km. More, than 90% of the river's load discharge were transported through the Chorokhi Canyon. The stability conditions of submarine sediments are disturbed by changes in the tangential reaction between soil particles or blocks, increased pore pressures, storms, instability of the underlying rocks, structural motions, tsunamis, earthquakes ( e.g. stability conditions has been violated by strong earthquake occurred in Turkey on 14-th of January,1999).Conducted research deals with the analytical considerations of dynamical processes occurring in the given area.
