| Abstract | ||
| The sediment pollution consider one of the negative effects to the river by entrance of many quantities of loose sediment carried by the water then stay in the channel at the bottom and banks caused the river islands with many negative effects such as the narrow and shallow of the channel , as it happened in Tigris River now, we used the remote Sensing techniques to study that effect within period of many years . Three case study chosen in north and middle and south of Tigris river course . using satellite records and historical maps we get the sequence of maps in different periods and by matching to gather and by mechanism of sediment we get the exact regions of growing island and the threaten places that maybe in future covered by sediments .Tigris river now in bad condition by the increase of sediment in the channel because of The low level of discharge and the great possibility to narrowing of channel in some places its decrease with 62% and the increase the total number of islands and their areas .We give suggestion to remove the sediment from the channel and give sudden Discharge huge quantities of water from the dams to push out the cumulative sediment there . | ||
