Water harvesting in Iraq is an old application with limited extent. Western Desert, Jazeera Desert and Eastern Valleys, are the zones were the water harvesting must be employed. Several water harvesting dams in Western Desert had built since 1970s, these dams are intended to provide habitat and recharge of groundwater resources. There is limited opportunity to recharge groundwater in Jazeera area due to existence of gypsum layers. Regarding Eastern Valleys, the experience of building water harvesting dams on the valleys manifested that sediments accumulation is the main obstacle to adapt this solution. Hemrin Hills considered as one of the most intensively eroded areas in Iraq, so, soil conservation and water harvesting development is important. Many small dams were built in mountainous zone in the last two decades, some are important for agriculture expansion, but there is need to evaluate the effects on large dams feeding. North-Eastern parts of Jordan, which has similar natural conditions of Northern Desert, had present a successful example of water harvesting development.
