CORUH RIVER WATER QUALITY • Water quality in the main course and tributaries of the Coruh River measured and analyzed regularly from existing stations • According to Turkish Inland Water Quality Standards (derived from Water Pollution Control Regulation) Water Quality of Coruh River generally Class I and Class II (Unpolluted and Less polluted water body) • General Pollution Sources: � Households, municipal wastewaters and dump sites U. Sezer GENERAL DIRECTORATE OF STATE HYDRAULIC WORKS (DSI), TURKEY 8/17
CORUH RIVER BASIN ÇORUH BASIN DEVELOPMENT PLAN • Çoruh River is one of the significant water resources of Turkey, especially in terms of hydropower potential • The preliminary study for development plan started in 1962 by General Directorate of Electrical Power Resources Survey and Development Administration (EIA), • The Master plan for hydropower development of Çoruh River was prepared in 1982 • In the master plan and subsequent studies various options were considered for the Coruh River Development Plan and as a result 10 hydropower projects in series along the main river in a cascade style were proposed on the main course of Coruh River U.
