Al-Hammar Marsh water hydro chemical changes and their negative effect

Abstract

Fresh water is the most important basis for continuous ecological and suffer from declining as a result of drought and increasing consumption with people number increasing .Ecology of Hammar marsh in the south of Iraq is a complete nature by its inhabitant and its plants and animal resources . As well as its natural prosperities , which has great role in ecological balance in the region . However , drying project and continuous decrease in water quantity in the marsh , its area , deferring in hydraulically and chemical properties and increasing its salinity . Therefore, this subject appear after marsh suffer from different ecological changes resulted from drying and it effects on ecological system. The objective of this study was to determine and evaluate hydrological and chemical changes of Al-Hammar marsh . Natural ecological changes as increase its water spaces, water supply , climate circumstances and quality properties of water and economical resources .
