CORUH RIVER BASIN CLIMATE

  • The Climate of the Coruh River Basin is

continental and Black Sea climatic conditions

  • Climate varies greatly due to;
  • high mean elevation of the land (1 132 m)

and

  • the influence of the mountainous areas

running parallel to the coast line

  • Mean annual rainfalls varies between 250 mm-

2650 mm

CORUH RIVER WATER QUALITY

  • Water quality in the main course and tributaries
  • f 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

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

CORUH RIVER BASIN ENVIRONMENTAL IMPACT ASSESSMENT (EIA)

  • Environmental Impact Assessment Report (EIA)

for Yusufeli Dam was prepared by ENCON in 2006 to fulfil the requirements of international standards,

  • The EIA Report Assess in detail:

The effects of the project on the natural and socio-economic environment, The respective mitigation measures including resettlement action plan

CORUH RIVER BASIN

  • 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
