The present work aims to develop an integrated plan management to utilize the rainwater and floods in Wadi Zalaga at Wateir region, South Sinai that can be applied in other dry and semi-arid desert areas of Egypt.  For such reason, we have to build dams and artificial lakes to feed the groundwater aquifers in these areas. The results of this research indicated that planning should not be limited to the establishment of projects only, but needs to consider the possibilities of using the hydrological cycle and the advanced technologies for the development of water resources through studies aimed at exploring all available areas to increase those resources on a good technical and economic basis. The collecting of floodwater is an integral part of flood management and its efficient use is essential for any integrated development project. This also may play an important role in reducing the bleeding of groundwater wells. In conclusion, the Artificial felling of groundwater aquifer of floodwater during flood periods is one of the most important techniques that save the water resource. Also, the use of floodwater to improve the quality of groundwater currently is available in addition to the protection of water from the possibility of pollution in the case of water surface. Generally, the improvement of both qualities of groundwater and protection from pollution are factors contribute to raising the available water possibilities.
