ABSTRACT The nature of the bed sediment material distribution in the Mosul dam reservoir is studied. A total of 37 bed sediment samples from the reservoir were collected. The laboratory analysis revealed that the dominant fraction of surface bed sediments is silt (64.8%) followed by sand (19.6%) and clay (15.6%). Furthermore, the dominant ranges of the sediment along the bed were 10% to 30 % for sand, 50% to 70% for silt, and 20% for clay. The percentage of clay in the bed sediments increased from the upstream reach of the reservoir downstream toward the dam. The D16, D50 and D90 values decreased toward the dam with a small decrease toward the upstream of reservoir near the confluence of the old Tigris River and the reservoir. Finally, relatively homogeneous bed materials represent about 18% of the total reservoir bed area. Reference: Al-Taiee, T.M. 2005. Distribution of bed sediment material in the Mosul Reservoir, Iraq.
