  • قطاع المياه الفلسطيني وأثر الصناعات الإسرائيلية على المصادر المائية
  • Published at:مؤتمر الصناعات الإسرائيلية في المناطق الحدودية والمستوطنات الإسرائيلية جسور سلام وتنمية اقتصادية، أم دمار للإنسان والبيئة؟
  • كما هو معروف فإن المصادر المائية في فلسطين تعد المحدد الرئيسي لتطوره الاقتصادي والاجتماعي، إذ لا تتوفر لهذا البلد خاصة مع وجود الاحتلال الإسرائيلي واستنزافه للموارد المائية على مدار سنوات الاحتلال الموارد المائية الكافية لتلبية حاجاته للاستعمال المنزلي وللاستعمالات الصناعية ولتزويد المشاريع الزراعية بالاحتياجات المائية المتاحة، علمًا بأن المصادر المتجددة المتاحة منها قد استغلت بصورة شبه تامة. إضافة إلى هذا الاستنزاف الجائر للمصادر المائية فإن قطاع الصناعة الإسرائيلي وخاصة الصناعات المجاورة للمناطق الحدودية والصناعات في المستوطنات الإسرائيلية فه

  • Towards Sustainable Management of Jerash Watershed: The (SMAP) Project
  • Published at:ARAB GULF JOURNAL OF SCIENTIFIC RESEARCH Volume: 26 Issue: 1-2 Pages: 107-114 Published: MAR-JUN 2008
  • With limited resources and rapidly increasing demands, sustainability is becoming an increasingly important issue, yet difficult goal to achieve in wadis (Salih and Ghanem, 2003). Sustainability of wadi systems is more complicated due to the conflicts and interactions among the different resource utilizations. Therefore, sustainability of wadi systems, and rather any natural entity, can only be achieved through an integrated management approach. In this study, an attempt is made to summarize the challenges facing sustainable development of a wadi system (Wadi Jerash) and to propose some solutions towards achieving that goal. The challenges considered in this paper include technical, socio-economic, environmental, institutional, political and legal aspects. Wadi Jerash project area, defined as the surface catchment of the Zerqa River in Jordan, is taken as an example due to its characteristics as a natural environmental set-up that need to be managed in a comprehensive and sustainable manner. The proposed meth

  • Evaluation of Water Management Options for More Food Security in Palestine
  • Published at:Twelfth International Water Technology Conference, IWTC12 2008, Alexandria, Egypt
  • Water management options for more food security in Palestine were evaluated using WEAP simulation model. A water management structure consisting of eight interrelated modules covering all aspects of water management was used. Three potential future political scenarios were tested: the current, a consolidate, and an independent State order. Simulations indicated that political status has decisive impact on water availability and the level of unmet demand and accordingly on present and future food security in Palestine. Water management, water trading, and water cost modules resulted in reductions in future water demands and therefore have positive impact on food security in Palestine.

  • GIS-Based KW-GIUH Hydrological Model of Semiarid Catchments: the Case of Faria Catchment, Palestine
  • Published at:The Arabian Journal for Science and Engineering, Volume 32, Number 1C
  • Among the most basic challenges of hydrology are the quantitative understanding of the processes of runoff generation and prediction of flow hydrographs. Traditional techniques have been widely applied for the estimation of runoff hydrographs of gauged catchments using historical rainfall–runoff data and unit hydrographs. Such procedures are questioned as to their reliability and their application to ungauged, arid, and semiarid catchments. To overcome such difficulties, the use of physically based rainfall–runoff estimation methods such as the Geomorphologic Instantaneous Unit Hydrograph (GIUH) approach has evolved. This paper models the rainfall–runoff process of Faria catchment using the lately developed KW–GIUH. Faria catchment, located in the northeastern part of the West Bank, Palestine, is characterized as a semiarid region with annual rainfall depths ranging on average from 150 to 640 mm at both ends of the catchment. The Geographical Information System (GIS) techniques were us

  • Management Options of Wadi Faria Baseflow
  • Published at:Eleventh International Water Technology Conference, IWTC11 2007 Sharm El-Sheikh, Egypt
  • The availability of adequate water of appropriate quality has become a limiting factor for development, worldwide. In arid and semi-arid regions, where water scarcity is a dominant problem, the overexploitation of water resources threatens to deteriorate the availability of these natural resources. Wadi Faria catchments, located within the Jordan River Basin in Palestine, are under arid and semiarid conditions as characterized by the scarcity of its natural water resources and the low per capita water allocation. Wadi Faria is a perennial stream in which 11 fresh water springs form the baseflow. Annual discharges from these springs vary from less than 4 to 42 MCM with an approximate average of 13.5 MCM. These available water resources have sustainable-yield limits that do not meet the water needs. Management of the available water in Wadi Faria is essential for the sustainable development of the area. This has compelled the motivation for developing a set of management options to optimally manage the basefl
