The water needsfor irrigation projects in Karbala A study in the geography of water resources

Abstract

The exploitation of water resources  necessitates  the increase  in efficiency  and reduce  in  water wasting . This could  be done  by  knowing  and specifying   water  needs  for the crops   that being considered  the basis of  agricultural  project 's success , along with supplying the plants with  sufficient water  and with specified periods , as to prevent the waste  or to prevent shortage  in water .  This could be  based on many factors   including ( the atmosphere , its elements , type of crop, soil type  and to what extent it preserves  the water) . Most of irrigation   projects  have been established  in a period of time where water shortage has been not sufficiently  estimated  ; these projects have not been witnessed  development  as to pace the modern technologies  under the dry and hot climate .  This actually resulted into diminishing ratio of lands  that could be implanted  with rain water . Thus , it is necessary to establish  irrigation projects as to secure   continuous  agriculture . When considering the water needs  and irrigation technologies , these  factors  specify   quantity of water  that being sufficient for irrigation  and specifying areas  of farmlands that rely on methods  of irrigation  and type of crop decided to be planted  in the governorate.
