Abstract

Iraq is facing a water shortage problem, which is becoming more severe with time. Rain water harvesting (RWH) can help to minimize the water shortage problem. Seven years of rainfall records were used to find out the quantity of water that can be harvested using a watershed modeling system (WMS). Koya city is located in the northern part of Iraq. The population of the city is about 39,484.The application of the WMS model for rainfall records of seven years (2002/3 to 2010/11) showed that 275.51 million cubic meters of water can be harvested. This implies that the annual average of rain harvested water is 39.4 million cubic meters and the allocation per capita to be 997 cubic meters per year. This amount of water can greatly help the development of industry and agriculture in the city. Keywords: macro rainwater harvesting, Koysinjaq, Kurdistan region, Iraq.
