Natural factors and their impact on the geographical extension of Drainage Grid in Central Mahaweel and Imam Districts

Abstract

Abstract

      The study of natural factors their impact on sewage water and its supplies in the area of study which contributes in Causing quantitative and qualitative changes in the sewage water. So, these factors have an important impact on the quantity and quality of water resources in any geographical region. This effect, therefore, differs according to the quality and characteristics of each factor that finds in the area of study. Also, the important natural characteristics in the area of study are clearly identified, the factors structured including geological structure, surface, climatic characteristics, water resources, soil and ground water and natural vegetation). Also, the types of trocars are identified whether they are major, subsidiary, secondary or grouped. And knowing the extent of drainage wet, extent of their spatial variation and the impact of this geo-variation on the characteristics of sewage water.
