CORUH RIVER BASIN CONSULTATION AND COOPERATION BETWEEN TURKEY AND GEORGIA Consultation between Turkey and Georgia regarding the hydropower development on Coruh River were started in 1996 with construction preparations for Deriner Dam. Since then Turkish and Georgian experts have been conducting joint studies that will serve to identify, monitor and evaluate changes, which may occur over time in the downstream of Coruh projects on the Georgian section of the river, including the mouth of the river and the Black Sea Coastline U.
