Fresh water is considered as a top priority concern that captures Syria because of limited water resources and high rate population growth (2.52%). This paper focuses on virtual water concept and studies the possibility of utilization it in agricultural sector, and calculate the water balance of Syria accurately. The virtual water volume was calculated for most of the crops that are planted in Syria and the total water footprint and its indicators were calculated. A mathematical optimization model is developed for the selection of the cropping patterns distribution in Syria that use water with higher efficiency and better economic income, and minimize the food gap by offering two scenarios. As a findings of this research, the food demand was not covered completely but mostly because of water shortage, and the food gap value was decreased in the first scenario from 10950 million Syrian pounds to 9850 million Syrian pounds and to 5100 million Syrian pounds in the second scenario because of the productivity improvement of some crops and the increase in the production of some crops (wheat, maize) which are the main crops in food balance.

The research aims to estimate allocated to quench agricultural areas in the coastal region, the amount of water during the period 2002-2012 in case of the use of modern irrigation (drip and sprinkler irrigation) instead of the traditional surface irr igation according to water legalized each method and the rate of efficiency, as well as to estimate the losses in irrigation networks allocated to agriculture and the development of appropriate pricing mechanisms of government. Find the historical and descriptive approaches adopted, and it was the most important results: 1- The results showed that if the use of drip irrigation surface irrigation in the quench-based surface irrigation acreage allowance contributed to supply up to 40% of the water used in surface irrigation amounts, and an average (174 973 785) cubic meters during the period 2002- 2012. 2- The results showed that if the use of sprinkler irrigation surface irrigation instead of the quench-based surface irrigation acreage for contributed to the supplied amount to 28% of the water used in surface irrigation amounts, and an average (122 481 649) cubic meters during the period studied. 3- economic pricing of agricultural water demand for current pricing varies, it was found that there is a deficit in the recovery of operating and maintenance costs of the territory of farmer beneficiaries of the water public irrigation networks and adult (21,500) per hectare, compared with what is being collected (3500) for. Q per hectare.
Seventh sector is located on the right bank of the Euphrates River at the town of Abu- Kamal, the Syrian-Iraq border, and its square 18140 hectares. Invest most heavily sector too, where crops depend on irrigation, irrigation networks mediated cons isting of earthen trenches, canals and to pump water by pumps on the banks of the Euphrates. Research aims to assess the pedelogical properties of agricultural soils by using laboratory and field tests: leaching speed, permeability, density, porosity, water field capacity, natural humidity (hygroscopic– wilt limit), so as to contribute in choosing optimal modalities for irrigation and drainage, and rehabilitation Land affected by salinity and exited the investment. The soils of the sector are clay, clayey sand, fine sand, and it has low permeability, low water field capacity because of sedimentary origin, and the total porosity is low in the upper part of subsurface soil because of its impaction. There is a relationship between hygroscopic moisture of soils and its structural composition. The search recommend to agriculture Fabaceae crops with different roots deep to help improve soil building, and need to use spray irrigation method to control the water quantity and wetting depth.
The research aims at know how is the harmony between the role of Strategic Management Process in managing the crises of the organization under study , and required role of the Strategic Management Process in Crises Management . The most important results of the research is : the shortage in that harmony. The reason is the big difference between the role of strategies design in managing the crises of the organization under study and the required role. While there is a good harmony of the role of the strategic implementation, strategic control process of crises managing in the organization under study and the required role. The recommendations: reconsider the way of design the organization mission, strategic analysis process , audit the signs of its crises after discovering it. Asking training responsible to imitate crises can be imitated.
The Seventh sector is located on the right bank of the Euphrates River at the town of ALbu- Kamal, the Syrian-Iraq border. Invest most heavily sector too, by planting different crops which irrigated by irrigation networks consisting of canals and ear then trenches. Research aims to evaluate the salinity of agricultural soils and unconfined groundwater by doing field surveying of agricultural soils of horizons from ground surface till depth 200cm. and making detailed chemical analysis of free groundwater and evaluate the quality of it to determine the salinity regions and the salinity degree. The salinity of agricultural soils of the sector are sulfate-chlorine and little degree chlorine - sulfate and chlorine classified non salinity –little salinity and little degree moderate salinity to very highly and highly salinity. The salinity of free groundwater between 1.3-28.5 g/l. and classified chlorine sulfate-magnesia calcic and sometimes sulfate chlorine- calcic magnesia. The research recommend to study and determine the leachingrequirement of salinity regions from actual test or choosing the most appropriate experimental equations.
The third sector of lower Euphrates basin has a great economic importance, but some lands have gone out of service because of salinization due to the rise of groundwater levels. Thus, it is very important to solve the ground water issue using new s cientific techniques. This research aims to solve the drainage problem in the third sector using a scenario based on a mathematical model, the results of which allow us design a proper drainage network comprised of 111 wells scattered all over the study area, with a total abstraction of 269000 m3/day. This will lower the groundwater level, dry the swamps, and decrease the soil salinity, ensuring a sustainable economic exploitation of agricultural lands.
