Groundwater Dependent Ecosystems In Arid Regions

Groundwater dependent ecosystems with respect to groundwater recharge are subjects of question nowadays especially if the environmental protection can be exaggerated. This research is conducted in response to the growing concern about potentially unsustainable groundwater level declines local subsidence and degraded groundwater dependent ecosystem in many basins and common recognition that further action is required to promote and achieve groundwater sustainability throughout WadiWatir as arid region. This book aims at estimating the recharge rates based on the current knowledge for two different scenarios using Hydrus and GIS programs: (a) the first scenario is to simulate the groundwater recharge process under the normal conditions and (b) the second scenario is to simulate the groundwater recharge process taking into account the effect of dam structures (e.g. water harvesting structures) located at the outlets of the main sub-catchments. The book includes an ecosystem assessment to examine the ways links are made between ecological systems structures and water sustainability.
