| Summary: | The process of settling of suspended material by the process of gravity is known as
sedimentation. It was a natural process that carries the materials such as stones and sand
that form layers of solid at the bottom of water flow. Particles are deposited when the
velocity cannot supports the particles anymore, which removed from the flow with the
help of gravity. The main objective why this study is carried out was to determine and
o1éry'e if there was any effect of the Hver characteristic on the pattern of the sediments
deposited. The size distribution of the sediment was also determined at every river
characteristic, to prove if the river characteristic also affects the distribution of the
sediments. One river model was designed with all the characteristic to be used in this
study. The river model was not designed using the actual river scale because the study
was only based on the river features. The experiment was run in a few sets with different
sediment placement. The water flow generated the sediments and form different pattern.
The pattern is then observed and captured. The samples of sediment at selected location
in the river model were sieved to identify the size of sediment. Observation from the
captured image of the river at studied point, shown that there are different pattern of
sedimentation due to different river features. This show that the river features also affect
the procesof sedimentation. Sediment size distribution and flow strength are the factors
that effect on sediment transport rates in the rivers. From the sieve analysis, it can be
observed that the size of the sediment is different at different point of the river. |
