Résumé
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. It 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 subcatchments. The study includes an ecosystem assessment to examine the ways links are made between ecological systems, structures and water sustainability. Understanding interconnection among the ecosystem and the human benefits is fundamental for the development of effective assessment, methodology and policy to achieve sustainability of water resources and better ecosystem health and services. The need to assess the effects of variability in geology, climate, biota, ecosystem and human activities on water availability. As global concerns over water resources and the environment increase, the importance of considering groundwater and surface water as a single resource has become increasingly evident. Overall, the recommendations call for an immediate intervention to study scenario analysis and impacts are required to predict the recharge behavior in the future to get effective groundwater management and healthy ecosystem.
