dc.description.abstractRapid development near the river systems can contribute to morphology changes due to increased or decreased sediment carrying capacity, erosion and deposition along the channel. Understanding the sedimentation processes in the river engineering, and hydraulic structures are of vital importance as this can affect water supply for the agricultural lands in the command area. To understand the problem, frameworks of physical and mathematical modeling were applied to investigate the flow and sediment pattern at Ijok Intake, Ijok River, Malaysia. HEC-RAS (1D modeling) and CCHE2D (2D modeling) software were used as the mathematical model where results from HEC-RAS were used as input for CCHE2D. Physical model was designed and constructed with a 1:15 undistorted scale at REDAC physical model laboratory. The comparative study using both models was performed by running simulation for ten different conditions without and with intake structure. Based on the results, it was proven that sediments were accumulated in front of intake structure and reduce the flow capacity to convey water into the canal downstream. However, for simulation using intake structure, physical model can predict the flow and sediment transport phenomena accurately because CCHE2D model used simplification and modification to represent an intake structure. Thus, it can be concluded that combination of the physical and mathematical model can be analyzing the river sedimentation near an intake structure for further design mitigation works.en_US
