Background: This study was conducted to evaluate the production of two fodder crops; common vetch (Vicia sativa L.) and Alfalfa (Medicago sativa L.) irrigated with treated wastewater. The study was implemented during summer 2015. Methods: Four water regimes were used in the experiment including: Irrigation with fresh water (control), fresh water su...

This study examined the effect of reused treated grey water on yield of 10 pearl millet accessions (Pennisetum glaucum) in An-Najah University, Tulkarm, Palestine. Ten pearl millet seeds were planted during May 2010 in each separate plastic containers (35 x 50 x 15 cm) filled with 45 kg sandy clay soil in four replication of a completely randomized...

The effects of different levels of nitrogen fertilization (0, 2, 4, 8 and 16 kg N / dunum) on the production of three wheat varieties (780, Lakeesh and Anbar) were studied. The experiment was conducted for two successive seasons 1994 and 1995. In the second season (1995) a higher nitrogen fertilization rate (16 kg N/dunum) and a third variety (Anba...

More than 30 % of Europe's land surface is made up of karst exposures. In some countries, water from karst aquifers constitutes almost half of the drinking water sup-ply. Hydrological simulation models can predict the large-scale impact of future environmental change on hydrological variables. However, the information needed to obtain model paramet...

This paper evaluates technical, legal, social and economic challenges facing treated wastewater in the West Bank as an example of arid and semi-arid areas. Although treated wastewater reuse is recognized as a strategic option in augmenting agricultural water supplies in arid and semi-arid areas, there are many challenges that face the utilization....

A hydroponic system as decentralised wastewater treatment and reuse was tested. The hydroponic system was built in a greenhouse in order to improve growth conditions for plants including orchard trees, vegetables and flowers. The experiment was conducted from 2007 until present, in a model greenhouse which was installed at An-Najah National Univers...
Article
There is a critical lack of sanitation in the West Bank (Palestine).Most domestic sewage is disposed of into unlined cesspits or septic tanks, or directly discharged to the environment without treatment. Water resources in the West Bank are limited, and nearly 70% of the water is used for agricultural irrigation. Reuse of treated (reclaimed) wastew...

Global climate change is predicted as a result of increased concentrations of greenhouse gasses in the atmosphere. It is predicted that climate change will result in increasing temperature by 2 to 6°C and a possible reduction of precipitation of up to 16% in the Mediterranean basin. In this study, the West Bank is taken as a case study from the Med...
Article
Middle Eastern countries (ME) are expected to face severe water shortages in the near future. As most conventional water resources are already developed or over exploited, there is a need to develop non-conventional options to bridge water shortages. These options include brackish and sea-water desalination and fresh water imports from outside the...

This research work intended to study the impacts of irrigation water containing various levels of copper, lead, and zinc on adsorption capacity of soil packed in 4 plastic columns and obtained from two locations around the city of Nablus: Salem (A) and Deir Sharaf (B). Results of simulation experiments showed an increase in the copper, lead, and zi...

A model to solve the hydraulics of trickleirrigation units is developed in thisstudy. This model is based on utilizingNewton Raphson technique. The modelconverts laterals into equivalent outletsthrough utilizing a simple power relationbetween inlet lateral discharge andhydraulic head. This relation is obtainedthrough least squares analysis betweeni...

Shared aquifers are a major source for domestic and agricultural water supplies in both Palestine and Israel. The western aquifer extends from the mountains of the West Bank to the coastal areas of Israel. The direction of flow is generally towards the west in this aquifer. The northeastern aquifer extends from the northern areas of the West Bank (...

This study presents a comparative analysis for three techniques in analyzing the hydraulics of pressurized irrigation systems: Linear Theory, Newton Raphson, and Iterative Distal Outlet. It was found that the iterative distal outlet method uses less computer time and memory than Newton Raphson and Linear theory methods in analyzing the hydraulics o...
Article
The utility of optimal-control theory for the deterministic operation of very large multireservoir systems is demonstrated for a real situation, the complex multireservoir Mahaweli system in Sri Lanka. This system includes 19 nodes, or reservoirs, and 35 release links. The model developed for the Mahaweli is designed to minimize a hydroelectric ene...
Article
Systems engineering research is conducted to analyze improvements in performance of a water-storage and -distribution system in response to improved monitoring of irrigation demands. The Mahaweli system in Sri Lanka, a multireservoir system with both hydropower and irrigation objectives, has been selected as a case study. The operation of the Mahaw...
Article
This paper presents a procedure to evaluate subsurface trickle irrigation systems. The procedure allows determination of the reduction in emitter flow rates due to plugging and other aging factors, even if the original flow capacity of the system was not measured. The procedure uses a computer model to determine discharge of a system, as installed,...
