Assessing water consumption and aquifer discharge through springs based on the joint use of rain and flow data in the Yarmouk River Basin

摘要: The method is proposed for assessing water consumption in the transboundary basin under scarce available data on exploitation of resources. based analysis dynamic rain–flow relationship which confirms consistent flow decline during subsequent sub-periods as a result increased consumption. was applied to Yarmouk River Basin up Maqaren Station. study area (6058 km2) includes Syrian (more 80%) and Jordanian territories. present provided complete information from Syria (1971–2009) confirmed its significant impact reaching Jordan (downstream area) aquifer discharge through springs. During 1997–2009 total estimated 76% Natural Flow vs. 24% measured at Similar estimates surface groundwater are 82% 67% 18% 23%, respectively. In 2006–2009, annual (total, SW GW) critically reached 95–100% Flow. perennial base Station caused by outflow springs outlet section Hreer tributary, represents local discharge. Its mean value assessed 120 MCM (40% natural flow) but it decreased almost dry-out 2006–2009 conditions level depletion drying unrestrained pumping groundwater. These results useful balance estimation well assessment management resources Jordan. can be adapted real-time monitoring (Syria). other areas with problems relations limited use.
