Abstract
In Perak, Malaysia, river systems with sand beds have been mined for decades. Due to a lack of sustainable management, these activities have resulted in a variety of difficulties, such as riverbank erosion, riverbed degradation, sedimentation, and a decline in river water quality. Excessive sand removal has the potential to substantially alter the natural balance of a river system. Consequently, it is crucial to do more research on river sand mining to develop suggestions for the long-term management of sand mining operations. Sediment flow in open channels is a physically difficult process that has not been fully investigated. It influences the shape of the river, which is continually changing due to its sediment delivery mechanism. Utilizing the Hydrologic Engineering Centers River Analysis System (HEC-RAS) software, a one-dimensional sediment river profile was generated. There were seven cross-sections (L1-L7) along the 3.16 km of the river had been simulated from 5 October to 24 October 2021. The simulation was conducted by entering the river geometry data, flow data, and sediment data. In addition, the Yang equation was utilised in the HEC-RAS simulation. The river profile revealed the deposition and erosion of the riverbed. From the simulation, only Line 5 shows the deposition process, while another six lines show the erosion process. Analyses of sediment modelling have found significant physical environmental implications. A discussion of the findings and some solutions for sediment management to prevent the deterioration and aggradation processes were presented.
