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.
