The research included descriptive analysis depending upon describing relations within the field (scope) of the study in order to find solutions for problems facing the usage of waters in Iraq by analyzing phenomena related to water resources and the best ways in using them . Throughout the next two decades, the problem will increase seriously in the light of the supply of Iraqi water resources and the increase of demand upon water resources due to the increase in population and the increase of water needs in various uses from another . The deterioration of water positions will be reflected severely upon agricultural production . The increase in demand for water resources for unagricultural uses will be actually an adverse effect upon the fixed supply for these resources and on the expense of resources not specialized for agriculture . Infact, the main aim in this field will contain two parts : the first is about developing and protecting water resources and this from the side of supply . the second is about good usage of water resources from the side of demand . These factors are connected with technical issues constituted in the frame work of water policies related to the topic .
