| description |
The main purpose of this study is to study sediment transport characteristics at Langat
River. Langat River is located in the state of Selangor and it is subjected to regular
flooding. Sediment transport capabilities can be known by using Hydraulic Engineering
Center's River Analysis System program (HEC-RAS). The appropriate data required to
create the model. The data needed to use in HEC-RAS is cross sectional data and
elevation data. HEC-RAS can create the sediment transport and hydraulic models. The
sediment transport model will calculates sediment transport capacity with a number of
available methodologies. In this research, HEC-RAS can show sediment transport. The
HEC-RAS model can calibrate and gives the values of Manning's coefficients of
roughness for the Langat River. HEC-RAS also can predict the changes of bed
elevation. The model will conclude that there is a significant increase in river bed depth
due to development, which means there is no change in flooding behaviour was
detected in the short term. This paper will be focused only on bed load sediment. The
result of 6 years stream flow shows there are some area had faced sediment transport
and erosion of the river. By using the England Hansen function in HEC RAS had shown
a little change in the river. From the simulation, the result shows the section that
experienced sediment transport at station 943
(1.45km
from the upstream part at Bangi)
and station 959
(1.05km
from the upstream part at Bangi), and station 972 (725rn from
the upstream part at Bangi) that experienced the erosion of river. |
