This research aims to touch on one of the important themes and strategies concerning human life and his multiple, especially problems that have negative effects on the human environment, that is, geography same event hydrology, biology and other .. etc., is vital fields that affect the economic life of man and his environment. The problems of drought and water deficit and water deficit in the climate are one of the most important problems facing most parts of Iraq, particularly Najaf governorate clearly, the regions of the dry and semi-dry, thereby stimulating an interest in the areas of the terms of reference to consider carefully so serious problems reflected adverse impacts on the environment. That the study of these problems is of recent studies critical, especially with the increasing demand and competition for water sources for water posed a vital element in the presence of the living environment, have taken upon themselves the geographical great interest in these studies by examining the concepts of drought and water budget climate, desertification and the actual value of the rain, and identify quantities of surplus and water deficit and its effects on man and his environment, and therefore develop appropriate solutions to minimize those impacts. This will be addressed by this research as academic study on specialized aspects of the topic of almost all respects. This study identified four key dimensions searcher Investigation serialized as a descriptive analysis... I saw them included climatic characteristics of Najaf governorate, which researcher presented the main features of the most important elements of the climate (solar radiation, temperature, wind and humidity, precipitation and evaporation) was, according to the latest weather data, which showed that the maintenance fall within areas gases few rain. Turning researcher at the campsite II to the concept of drought and water deficit in the studies of climate and weather geographic methods by which Ahtsabhma practical indirectly through empirical equations for that. Enables a researcher at Mbgesh III of the application of the equations and experimental methods within the environment preservation, and thus access to the results, ie the volume of drought and the amount of water deficit in the province. Researcher used several variables most important equations may transmission and BLANEY Cradle and episodes and Thornthwait. After applying those Atrak, which showed that the preservation suffer from the inability of large water and dry climate is also significant, the researcher was able to produce a set of proposed solutions and potential to address the problems of drought and water deficit in the climate, which can be applied in practice within the atmosphere and preserve natural conditions (soil, water, plant., etc.), techniques that could be followed in order to achieve the development of water resources and rainfall and improved weather conditions and came in the fourth thesis research.
