Abstract [en]

River Tigris is a major river in Iraq. Sediment at the bed of the river within a reach of about 18 km starting at the center of Baghdad upstream was investigated. Sixty five cross sections were surveyed and 46 sediment samples were collected and analyzed. It was noticed that fine sand was dominating the bed (90.74%). The average median size within the reach was 2.49 phi (0.177mm) while the mean size was 2.58 phi (0.16mm). In addition the sediments were moderately sorted, fine skewed and leptokurtic. The size of the bed sediment relatively decreased compared to older investigations due to the construction of Adhaim dam on tributary which used to be the main sediment supplier to the Tigris River before entering Baghdad. Furthermore, the discharge of the Tigris River for the period 1983-2013 (715m3/s) had decreased by about 40% and 30% since 1983 compared with the period 1931-1956 (1208 m3/s) and 1956-1980 (1015 m3/s ) respectively. This had decreased the capacity and competence of the river. The bed elevation had increased compared to previous surveys. It was noticed that dredging operations and obstacles (e.g. fallen bridges and islands) disturbed the flow of the river and sediment characteristics in several sites.
