In general, sediment comprises many shapes and sizes. The sediment size can be small, such as sand,small pebbles and silt, or large such as boulders, which are normally found upriver. Sediments found in estuaries are mostly fingrained, such as sand and silt. The speed at which water flows in rivers plays an important part in determining its capacity to carry away sediments. Slower moving rivers will have a lower rate of sediment movement. According to Allison, J (1995), the process of sediment deposition is also dependent on river discharge and speed of river flow. As such, a higher discharge values and water velocity would result in higher amounts of sediment. In addition, time is a factor whereby the longer the sediment deposition process, the higher the sediment loads.Over a period of time, the high amount of sediment will settle down and the accumulated sediment will eat up the river bed thus causing the river to overflow or flooding. Thus, knowledge of the quantity, quality and dynamics of sediments is essential for managing our water resources systems and to against negative effects from happen.A study on sediment load was conducted at the Galing River in three different days which are 28/02/13, 13/03/13 and 27/03/13. Three sampling point representing the length of Galing River which is about 7.7km has been selected: Station 1 (S1) upstream Galing River, Station 2 (S2) mid-streams Galing River and Station 3 (S3) downstream Galing River (Figure 1). Sediment samples were collected using grab sampler. Three sample replications were collected from each station and the finding was presented by the average of the replicated samples. The samples collected were analysed in the laboratory.
