<![CDATA[Sedimentation is one of the main factors affecting the hydraulic capacity and performance of urban rivers. This study aims to analyze flow capacity and the impact of sedimentation on a river’s ability to convey flow optimally. Flow capacity analysis was conducted using the Frijlink method with a rectangular channel cross-section approach, while sediment distribution and accumulation were analyzed through hydraulic modeling using HEC-RAS software. The analysis results show that the river’s flow capacity is 3,381 m3/s. An evaluation of bed sedimentation indicates that observation point 3 has the highest sedimentation rate, with a sediment discharge of 2.85 × 10-8 m3/s/m and a sedimentation volume of 5.78 × 10-4 m3/s. The HEC-RAS modeling results show that the river’s capacity is unable to accommodate the flow rate optimally under high rainfall conditions, thus potentially causing local flooding or waterlogging.]]>
