| Abstract | ||
| The study area is located in the alluvial plain of Iraq, and specifically in the lower floodplain of the Tigris River, and a low naturally extends to a wide area and at a shallow depth and works a source of the floods when they occur, and it receives excess water for various uses. We are using ancient and modern maps with large scales to see the shape and space boundaries Al-Hawizeh Marsh, was the work mock maps of the area through a series of satellite images of different dates and with the help of remote sensing techniques. From the comparing to Al-Hawizeh Marsh area and make an exact time map of the marsh shows that the marsh has passed through several stages. Through this research that we shows the variance in the change recharges rivers rates that feeding of the Marsh at the months, seasons and years due to the climate changes of this region, where it was noted that the last time period had changed as a result of human intervention from the dams and barrages and canals and then launch water quotas by changing water policy, as well as the gripping desertification of this region. These factors mentioned above and the fact that Al-Hawizeh Marsh is one of the Iraqi largest marsh and is a Ramsar site with international significance, led to a large decline in the area because of decreasing of entering water and the decline of very large quantities and poor quality because of increases the salt concentration in it. | ||
