Abstract: The drainage system plays an important role in controlling surface flow to prevent the occurrence of puddles and flooding, which can discrupt community activities and damage road facilities. Insufficient channel capacity that does not match the design rainfall discharge is often the main cause of this problem. This study aims to evaluate the capacity of the existing drainage channels and design appropriate channel dimensions on the H.Basri Road section, Kotabaru Regency, with the study scope covering STA 0+000 to STA 0+200. The analysis was conducted by calculating the design flood discharge for 5-year and 10-year return periods as planning standards. The calculation results show that the design discharge for the 5-year return period is 0.225 m3/s, and for the 10-year return period it is 0.228 m3/s. Meanwhile, the measured capacity of the existing channel only reaches 0.173 m3/s. A comparison of these values proves that the current channel dimensions are unable to accommodate the design flood discharge for both planned return periods. Based on these findings, adjustments to channel dimensions or channel rehabilitation are required so that the drainage system can function optimally, as well as ensure the safety and comfort of road users from the risk of flooding. Keywords— drainage channel; design discharge; return period; channel capacity; rainfall.
