| 520 | |b This paper examined the impact of Zobe dam Reservoir on the physical properties of Bed-sediment and Bed-form at the immediate downstream of Karadua River in Karadua Catchment, Katsina state, Nigeria. Sediment samples were collected along the upstream and downstream of the river bed and was analysed in the Laboratory. The vertical section of the River bed was cut at the two river reaches and observed and examined in the field. The result revealed that the river bed upstream constitutes two layer-bands while, the downstream has three well distinct layers. The disparity between the layers also shows that amount of sand in the Bed load downstream of the reservoir is less than that of the Upstream with -28 percent. On the other hand, the amount of fine materials (silt and clay), downstream is greater than that of the Upstream with up to +33 percent. It is also found that generally, the thickness of the riverbed is grater upstream than downstream with an average of 26.8 cm and 14 cm respectively. The study concludes that the deficiency of sediment downstream is resulted by the trap action of the reservoir behind the dam. Secondly, the silt and clay layer downstream is a newly developed band resulted by the release of less turbid water from the reservoir. Further detailed study on bed-sediment is therefore, suggested and in all individual dammed river catchments. | ||
