Analysis of immersed geological formations for Bekhmeh dam reservoir/ Erbil

Geological formations areas measurements for immersion level have been got the Bekhmeh dam reservoir depending on digital elevation model (DEM) with resolution (10 m) and Global Mapper-GIS software, which deal spatial analysis get data of landforms. The immersed area each geological formation was determined separately all levels, from minimum (380m) to maximum one (600m) above sea level, (1 interval
 According these measurements, Aqra-Bekhme Shiranish highest value areas, (46386) m2 (33183) m2, respectively, form (19.6%) (14.01%) respectively total reservoir. These two were at most levels. Those consist hard rocks low solubility.The lowest (Naopardan Chile Formation) an (79) forms (0.03%) area; followed by Chia Gara, Barsarin, Nokelekan (164) (0.07%) .Those last three levels (570-600m). soluble friable unit, cause engineering problems, has area. That unit represented Fat'ha Formation, (16399) (6.92 %) In addition, it is far away body (1472) m. characteristics qualifies this location reconstruction dam.
