Abstract:
The marshes areas are the largest wetlands in the Middle East - have been subjected to a series of procedures and mechanisms that have worked on the draining of the marshes - which formed the biggest disaster befell them and changed in the early nineties as the hydraulic situation totally different after the desiccation operations and rehabilitation of the marsh - nature and of life milestones It changed as streams and rivers dried up and used a variety of mechanisms that have been able desiccating Marshes through organized campaign 1990 - 1998 resulted in the desiccating to reduce the water resource most of the region and subjected to full drought and high mimics the salinity and thus influence steady on the ecosystem and the emigration of the population, living organisms and the role of desiccation processes and re - flooding on environmental conditions and hydraulic and biological for the region and its impact and changes on the characteristics of the soil, regetation and the land uses. The aim of the research is the study of factors affecting the hydrologicaregimes on Hammar marshes in southern Iraq between latitudes 30,20 - 31,47 to the north and arc longitude 46,17 - 37,47 in the east between the governorate of Dhi Qar, Basra , represented by natural factors geological for matrons, climate, soil and natural vegetation and groundwater as well as human factors are working to give water each region its own features. The study also aims to texplaion of the hydrological regione for the sources feeding Hammar marsh, which includes hydraulic situation of the Euphrates River and hydraulic situation of Shatt al - Gharraf, hydraulic situation of the Almasabi Alaam , the hydraulic situation Alshafi and Algamij, also to study the hydraulic features of the feeding resources of Alhammar marshes represented by the yearly, quarterly and monthly discharge, because of its importance to know the temporal variations of the discharge through the monitoring of different periods in time to see the impact on the recovery of Hammar and clarify the relationship between discharges and levels. .The research aims to study hydrologically Hammar marshes from two sides , the first is to study passage system of Al - Hammar by studying the hydrological budget and its various elements Water for years differentiated the spectrum by knowing the amount and volume of water entering the Hammar from multiple sources and calculate the amount of extra and lost water from the marsh month to show deficit water and earned surplus by comparing to the choosen sample .second aspect of the study is for the regem Hammar, which included a study of the physical and chemical characteristics that determine the quality of water in Hammar, along with climatic factor affecting the basic elements (Heat ,moisture, evaporation ,speed of the wind as well as rain) and the prevailing vegetation of reeds and papyrus plants and determine the validity of the marsh water for different uses - agriculture, health drinking Agriculture craftsmen animals compared it with the international specifications for each use
