Tunca (Suakacağı) Dam and HEPP Irrigation Project (ru)
|Client||DSİ 11. Regional Directorate - Edirne|
|Duration of Services||2007 – 2010|
Brief Description of the Project:
The objective is collecting basic data, planning and design for irrigation water supply to arable lands on the Tunca Plain and hillsides utilizing water potential of the Tunca River in the Meriç Basin.
The project was accomplished in 2 phases.
Phase 1 - Planning
Planning services comprised irrigation of total 15 845 ha (gross) land using the water to be stored in Tunca Dam to be constructed on the Tunca River on the Bulgaria-Turkey border within Edirne Province. Planning services also comprised high-pressure piped irrigation system on total 13 575 ha hillside lands and open-canal traditional irrigation system, including weir, on total 2 270 ha bottom lands, and a HEPP of about 11,68 MW installed power at the toe of the dam, on the right bank of the Tunca River within Bulgarian territory.
Planning services comprised the following;
Bottom Lands 2 270 ha (Gross)
Hillside Lands 13 575 ha (Gross)
Total 15 845 ha (Gross)
Calculation Flow 319.00 m3/s
Design Flow 2.60 m3/s
Length 65.00 m
Height 5.15 m
Installed Power 11 680 Kw
Energy Generation 36.80 GWh/year
Installed Power 9 130 kW
Number of Pumps 11 duty, 2 stand-by
Flow 8.25 m3/s
Installed Power 90 kW
Number of Pumps 2 duty, 1 stand-by
Flow 2.60 m3/s
Reports Prepared in Phase 1:
Hydrology Planning Report, Agricultural Economy Planning Report, The Tunca River Flood Losses and Protection Benefits Planning Report, Natural Construction Materials Planning Report, Engineering Geology Planning Report, Planning Report and appendices thereto (Drawings Album), EIA Project Introductory File and Summarized Report (in Turkish and English).
Phase 2 - Design
Design services comprised high-pressure piped irrigation system on 13 590 ha area of hillside lands and 2 240 ha bottom lands, total 15 830 ha (gross) area. As basis to design, 1/5000-scale photogrammetric mapping in 1/1000-scale precision was performed by flights over the whole area.
Detail design for irrigation system included secondary and tertiary pipelines (384 822,95 m in total), primary pipeline comprising right bank pipeline (32 536.48 m) plus left bank pipeline (19 305.11 m), pump stations and engineering structures.
Design services comprised the following:
Bottom Lands 2 240 ha (Gross)
Hillside Lands 13 590 ha (Gross)
Total 15 830 ha (Gross)
Installed Power 15 000 kW
Number of Pumps 5 duty
Flow 11.375 m3/s
ETL 2 x (3 x 477 MCM) 13 km
