Geographical Analysis of Drainage in Al-Najaf Governorate and Means of Development

Abstract

AbstractAl-Najaf governorate has been considered as one of the most important of the agricultural areas. For its various agricultural crops. Particularly in the plane area that is characterized by the flat surface and the readily of making different agricultural processes .this area depends on the flow irrigation. Moreover using of other techniques for irrigation which characterized by the random structure.These random techniques leads to deteriorate the soil and its quality. The flat surface considered as a significant pointer to reflect the bad picture for the drainage and how it gathers near the ground causing of salt rising existing. Salt gathering is considered as one of the most important problems that are faced the agricultural crops in the given area .So we suggest to search with the most important tap in Al-Najaf governorate to find out the problems that in faces. These problems appear as the specialized persons with this domain neglect it. Besides the natural features for this area. This subject ordered us to search and study with the necessary techniques to get ride these obstacles in the agricultural processes firstly .and secondly for deter mining the enough water for each donam in the agricultural areas in the plane area.We can do this by treat these problems that are reduced the quality of water to determine the crops need for irrigation especially the problem of clay precipitation and aquatic plants.The studies also reached to interpret and analysis the data which were related with the necessity of putting the suitable treatments to maintain the drainage network to the giver area. Additionally the treatment of the dirty water that are coming from the agricultural soils and wake it as other source for agriculture after faltering it from the salt as the water shares for the agriculture areas could be not enough for it need during the tow seasons in the year.
