Musi V Bridge is one of the three bridges on the Kayu Agung–Palembang–Betung Toll Road. This bridge is the longest toll bridge in Indonesia and connects the cities of Palembang and Betung. It has a length of 1,684 km and a width of 17 m and is located in Gandus District, Pulokerto Village, Palembang City. Channel is one of the bridge constructions that functions to overcome flooding. This research aims to analyse the dimensions of pipe channels based on flood discharge to overcome inundation on bridge bodies. The analysis uses rainfall data from BMKG Station, Kertapati Station and SMB II Station. Data are processed using frequency analysis and suitability tests to obtain concentration times and hydrological discharge parameters. Data are then compared with the hydraulic discharge processed from the channel dimensional parameters. The evaluation results of the planning diameter are assumed to be 8 inches or 20.32 cm according to the guidelines, which state a minimum channel diameter of 200 mm or 20 cm and a minimum pipe installation slope of 2% for comfort. The results of the comparison of hydrological and hydraulic discharges show that all drainage channels are feasible.
