| 1 | Application of GIS-based SCS-CN method in West Bank catchments,Palestine显示文摘Among the most basic challenges of hydrology are the prediction and quantification of catchment surface runoff. The runoff curve number (CN) is a key factor in determining runoff in the SCS (Soil Conservation Service) based hydrologic modeling method. The traditional SCS-CN method for calculating the composite curve number is very tedious and consumes a major portion of the hydrologic modeling time. Therefore, geographic information systems (GIS) are now being used in combination with the SCS-CN method. This paper assesses the modeling of flow in West Bank catchments using the GIS-based SCS-CN method. The West Bank, Palestine, is characterized as an arid to semi-arid region with annual rainfall depths ranging between 100 mm in the vicinity of the Jordan River to 700 mm in the mountains extending across the central parts of the region. The estimated composite curve number for the entire West Bank is about 50 assuming dry conditions. This paper clearly demonstrates that the integration of GIS with the SCS-CN method provides a powerful tool for estimating runoff volumes in West Bank catchments, representing arid to semi-arid catchments of Palestine. | Sameer SHADEED Mohammad ALMASRI | 2010 | Water Science and Engineering2010，3，1： | 9 |
| 2 | Rainwater harvesting to alleviate water scarcity in dry conditions:A case study in Faria Catchment,Palestine显示文摘In arid and semi-arid regions, the availability of adequate water of appropriate quality has become a limiting factor for development. This paper aims to evaluate the potential for rainwater harvesting in the arid to semi-arid Faria Catchment, in the West Bank, Palestine. Under current conditions, the supply-demand gap is increasing due to the increasing water demands of a growing population with hydrologically limited and uncertain supplies. By 2015, the gap is estimated to reach 4.5 × 106 m3. This study used the process-oriented and physically-based TRAIN-ZIN model to evaluate two different rainwater harvesting techniques during two rainfall events. The analysis shows that there is a theoretical potential for harvesting an additional 4 × 106 m3 of surface water over the entire catchment. Thus, it is essential to manage the potential available surface water supplies in the catchment to save water for dry periods when the supply-demand gap is comparatively high. Then a valuable contribution to bridging the supply-demand gap can be made. | Sameer SHADEED Jens LANGE | 2010 | Water Science and Engineering2010，3，2： | 2 |
| 3 | Socio-Economic and Environmental Impacts Assessment of Using Different Rainwater Harvesting Techniques in Sarida Catchment, West Bank, Palestine显示文摘A statistically representative questionnaire targeted people using rainwater harvesting(RWH)techniques in rural communities of Sarida catchment,West Bank,Palestine was distributed and analyzed.The main objective of this study is to assess the social,economic,and environmental impacts of adopting RWH techniques(e.g.cisterns,concrete and clay ponds,Wadi ponds,earth dams,and stone terraces)in different uses to increase water availability.The results showed a simple sharing of the female component among beneficiaries,while concrete ponds and cisterns were the most used techniques.Actually,social impacts were noticeable by sharing the same RWH structure and reflected to responsibility skills and role exchange increases.On the other hand,RWH techniques showed a significant economic impact for end users represented by enhancing domestic,agricultural,and recreational activities leading to good profit increase.In addition to food security as output,the most important environmental impact was water wasting prevention,which in turn could be linked to sustainable water management and considered as universal challenge for future generations. | Marwan Ghaleb Ghanem Wasim Ahmed Sameer Shadeed Michel Riksen | 2020 | Journal of Geographical Research2020，3，2： | 0 |
