Physical Simulation to Determine the Surface Water Profiles and Point Velocities for The Flow Conditions of Sungai Bunus Stilling

Overthe years, Sungai Bunus has undergone hydrological changes and become lower narrower. Under a flood mitigation project, diversion channel is proposed to reduce the volume of water in Bunusfurthermore avoid spill over into Klang flooding events Kuala Lumpur city. This research describes physical modelling flow state stilling basin. Physical model was constructed verify design criteria basin that will be adopted for construction. Experimental work been carried out both with without piers under three specified discharges (52 L/s, 86 L/s 121 L/s) subsequently measurement surface height profiles point velocities through system. Consequently, there are no significant differences outcomes between two circumstances. The results show overflow at 52 L/s. level section starts on one side package when flowrate scenarios. All test conditions shown velocity measured beginning (inlet) much than reported near end (outlet).
