Abstract
The Mesopotamian marshlands faced a massive destruction from the year 1990 till 2003. This destruction leads to displace the marsh dwellers and decrease the numbers of flora and fauna in the region. After the war in 2003 in Iraq the rehabitation and restoration of the devastated marshland ecosystem started. In this study a survey was made on the physical and chemical characteristics of Al-Hawizeh marsh for an interval and creates comparison among these characteristics during the four season’s then format a relationships between water salinity and electrical conductivity and another relationship between turbidity and total suspended solid. It was found that the water quality of Al- Hawizeh marsh for most of the properties was good in summer time because of the flood water from Tigris and the other feeders of the marsh. Some properties of Al-Hawizeh marsh was coincide with the maximum allowable values of the Iraqi drinking standards (1986). The equation between the salinity and electric conductivity was exponential equation while between the turbidity and the total suspended solid was power equation
