Syrian Arab Republic considers one of the limited waters resources countries, comparison by increasing demand to all the needs. Syria located on the eastern coast to the Mediterranean Sea in the arid and semi-arid zone between altitude/32-37.5/N and longitude/35.5-42/E. Climate is distinguished by rainy short winter and long dry summer. The rainfall is different in distribution between the coast and the inside areas. Syria divides by the rainfall quantity to five agricultural zones. The fifth area represent is the minimized annual rains rate about 150 mm which is 55% from the country square, called the Syrian Desert (Badia). This area characterized flat area included some mountain series, clayey sandy firm atoms soil, little rains, and hard wind in the summer, high rate vaporization. The relative humidity changes according to the temperature. Syrian Desert (Badia) consider suitable environment to the meadows growth, the pastoral for that it considered the main source to feeding animal wealth, for the insufficiency rains in this area, the government established many vital projects foundation to development botanical cover in the area. And that by means of the rainwater harvest projects, for drinking aims, livestock, and irrigation in some areas. For incarnation by establishment 37 dams in separate places and different sizes to reserve runoff in winter and 50 mini-reservoirs, 7 spread water dikes in the flat wide valleys, terraces, in addition to excavation many of wells, plant the suitable pastoral plants in some the areas and all these projects aim for the utilization attempt as much as possible from drop water it falls on this area to development pastoral cover And the animal wealth and the function on the tenants stability within the desert. This paper includes study to impression Syrian Desert (the natural factors, the climatic factors, the pastoral cover, animal wealth the tenants...). and also study water resources management in it, and the followed techniques of rainwater harvest, conditions, and methods selection suitable method and administration.
