摘要：During the last 7 Centuries Tigris river had 38 extensive flood, The last one happened at 1988, Many areas covered with water with increase the level of ground water that caused many Negative effects on Agricultural areas near the river, To determine that series of Landsat satellite images used for years (1972-1988-1990) and digital supervised classification had done to calculate the areas of many classes (Water bodies -Salty soil- Bare soil- Vegetation- Unchanged areas) .The result showed that salty soil increased after the flood with 39% near the channel and about 439% far away the channel because of the increase of ground water level ,that mean real disaster . To determine the critical level of river water that pass over the levee of river we used 3D program that showed the level of (14m.sl.) consider safety level but at level (16m.sl.) been critical level and in (17m.sl.) the water pass over the levee and cover the areas around the channel and new extensive flood happen
