BATMAN RIGHT BANK IRRIGATION AND DRAINAGE PROJECT

Summary

Project located on Turkeys South-East Region in Batman and Diyarbakir province. Project water source is Batman Dam. Project based on Planning Report established in 1993. Project formulation is intermediate-pressure pipes that take water over from main channel. Pipes distribute water to the irrigation field. Main channel alignment mostly goes over roughly terrain and steep slopes. There for 12 tunnels must be construct on the alignment. Also many creeks must be passed for this reason 22 syphon must be construct. Project design several irrigation modulus. Project located in Batman and Diyarbakır province on South-East region of the Turkey. Project planning to irrigate right and left bank of the Batman River via water potential of this river. Project water source is Batman Dam which built on the same river. On the right bank there are Diyarbakır Province’s Silvan and Bismil district, on the left bank there are Batman Province’s main villages irrigation lands. Project contains 18.572 ha irrigation land.

Topography have weak grade on the upstream section. There are huge planes on the valley side. North side of the irrigation field Silvan District lays on west-east direction. South side of the irrigation field Raman heightens lays on west-east direction. Project field have deep subsidence both north and south. For south and north project field topography is rising. These rising topography have bare mountains and at the top of the mountains little planes. Subsidence topography pretty wavy.

Project main purposes are Diyarbakır Province’s Silvan and Bismil district, Batman Province’s rising population needs, produce more food items, offer business opportunity, rise populations standard of living. 

Main Channel and Structures

Batman Right bank main channel length 140 km. Water taken from Batman Dam transmitted to irrigation field with gravitational. Initial discharge of the main channel is 27.5 m³/s. Main channel is mostly have trapezoidal section, some sections are channel with the wall. On main channel there are 22 Syphon, 12 tunnels and 2 galleries.

Irrıgation Pipe Network and Structures

Right bank irrigation area is 18,572 ha and total pipe length 492,880 m. Pipe material is CTP, PE100 and diameters are variously 1700~110.

Irrigation module is 1.228 l/s/ha.
