Winter rains and possibly melting snow from Iran’s Zagros Mountains have begun to fill the marshes and shallow lakes of Southern and Eastern Iraq. Flooding in this region is an annual affair, though typically, the floods peak in April and May when spring snowmelt flows out of Iran. The false-color, Moderate Resolution Imaging Spectroradiometer (MODIS) image acquired on January 16, 2004, shows that water levels had already begun to rise one month in to the rainy season, which runs from December to April. Three weeks earlier, on December 24, 2003, the wetlands were somewhat smaller. The storms that brought water to the wetlands also left the mountains in Iran are capped with snow, which is light blue in this image.
Iraq’s marshlands are divided into three by the Tigris River in the north and the Euphrates River in the south. The two rivers converge to form the Shatt al Arab, which flows into the Persian Gulf. On the western banks of the Shatt al Arab, south of the Euphrates River, is the Hammar marsh. A black pool of dark water, Lake Hammar, dominates the marsh in this image. Directly north of the Hammar marsh, between the “v” formed by the Tigris and Euphrates Rivers, is the Qurnah or Central marsh. During the 1990s, much of the water that fed this marsh was diverted away by dykes and earth barriers in a campaign to control the livelihood of Marsh Arabs living in the region. (For more details, please see Vanishing Marshes of Mesopotamia.) After the fall of Iraqi leader Saddam Hussein, the dykes and barriers were removed. The third marshland, the Hawizeh marsh, sits on the Iran-Iraq border, east of the Tigris River.
Floods in the marshlands have already caused problems this year. In early January, rediverted water combined with heavy rains caused intense floods near Nasiriya, a little north of Lake Hammar on the shores of the Euphrates River. Over 8,000 people were evacuated, and at least 180 houses were destroyed.
