Reclaimed water provides an important contribution to the water balance in water-scarce Jordan, but the quality of this water presents both benefits and challenges. Careful management of reclaimed water is required to maximize the nutrient benefits while minimizing the salinity risks. This work uses a multi-disciplinary research approach to show that soil response to irrigation with reclaimed w...

a 35 year old diver comes to your office. he had hyperglycemia in his last check up. he asks if he can steel dive in spite of hyperglycemia. we reviewed the recent studies about diabetic persons who dive. recent studies have shown that well controlled diabetic persons may be permitted to dive, but if they have any problem such as diabetic nephropathy, retinopathy, neurological and cardiac probl...

introduction: lack of water and deterioration in the quality of soil and water resources are considered to be the prime cause of reduced crop yield in arid and semi-arid regions ‘more crop per drop’ by trickle irrigation, deficit irrigation, and uncommon water are the best strategies for mitigating water crises. different irrigation management strategies are needed to increase production in dif...

abstract the existence of various perceptions related to the efficiency of water use in agricultural sector can hamper the development of appropriate water resource conservation policies. particularly, when there has been an emphasis on increasing water use efficiency by improvement in irrigation systems. the main purpose of current study is to estimate excess water use for a sample of 15 farms...

nowadays, it’s very usual to use these models in almost all sciences. use of these models has provided quick, appropriate and economic answers to many questions. modeling is developing in different fields of agriculture, including irrigation and drainage. field tests are useful to determine and analyze the different irrigation management but there are significant limitations. the most important...

the price of water in agriculture plays an important role in the water allocation management. therefore, the optimum strategies of cropping pattern could be designed when water price analysis are considered in a predetermined economic framework. in the present study, a programming model was developed using the genetic algorithm for optimal water allocation in the eastern north of khuzestan prov...

Water-limited environments confound efforts to intensify plant production needed address the impending shortfall in global food capacity (Fischer et al., 2014). The additional influence of anthropogenic warming on extent water limitation key environments, not only through anticipated effects precipitation, but also via increased evaporative demand associated with higher temperature and vapour p...

This paper shows the real situation about management of water and wastewater in Lebanon and focuses on problems related to urban water pollution released in environment. Water and wastewater infrastructures have been rebuilt since 1992. However, wastewater management still remains one of the greatest challenges facing Lebanese people, since water supply projects have been given priority over wa...
