The study area is located within the western part of Iraq between Latitude
(32˚45'0'' - 34˚0'0'') North and longitude (39˚30'0'' - 40˚45'0'') East within
Anbar Governorate. It covers an area of 4767.423 Km 2 with elevation ranges
from 360 to 840 m. The general slope decreases from southwest to northeast.
Five old dams identified in the study area. The results of SWAT model
showed high curve number (70 - 85) indicating low filtration and runoff rate
(1.2 - 8.2) mm for the period (1994-2014). These dams have catchment areas
ranged between (118.03 - 673.41) km 2. They were to be used for agricultural
purposes. The results according to the Food, Agriculture Organization (FAO)
standards for their distance from agricultural areas using a GIS showed that
all are not suitable except dam number (1). The distance to roads showed that
dams (1, 4) are highly suitable, (2, 3) are low suitable and dam (5) is not suitable.
The average annual quantity of rain water that can be harvested from
the 5 dams is about 12.9 million cubic meters.
