Abstract

Seri Medan, located in Batu Pahat, Johor, experiences frequent flooding due to heavy rainfall, sedimentation, and low-lying terrain. This study applies the HEC-RAS software to simulate sediment transport in the Simpang Kiri River, focusing on understanding flow characteristics, sediment deposition, and erosion patterns. Understanding sediment transport dynamics in the Simpang Kiri River is essential for addressing flood risks and river morphology changes in the river. The methodology includes data on river geometry, flow characteristics, and sediment properties, which are integrated into the HEC-RAS model for simulating sediment transport. The study identifies critical sedimentation and erosion areas, evaluates sediment transport rates, and explores the impacts on river morphology. The findings provide insights for sustainable sediment management and effective flood mitigation. The simulation is expected to identify key areas of sediment deposition and erosion, providing data that supports effective flood mitigation and sustainable river management.
