نهر اليرموك
Conventional water resources in Jordan consist of groundwater and surface water. Countrywide, twelve groundwater basins have been identified. In terms of sustainability, their state can be described as critical since some of them are exploited to their maximum capacity, while others are overexploited, threatening their future use. The long term safe yield of renewable groundwater has been estimated at 275 million cubic metres/year. The major surface water sources are the Jordan River, the Yarmouk River and the Zarqa River.
