Abstract: Rivers, as natural flow systems, possess dynamic characteristics. Mathematically, river discharge is greatly influenced by the river's cross-sectional area. However, due to its natural variability, the relationship between these two parameters can vary significantly. This study focuses on the correlation between flow velocity and discharge in the Walanae River, located in South Sulawesi, Indonesia. The study, which concentrates on the upstream, midstream, and downstream areas, includes data collection on river flow and cross-sectional area. Measurements were taken under both normal and flood conditions. The findings reveal differences in the mathematical relationships across the three locations, under both flow conditions. These variations in flow characteristics are associated with the condition of riverbank vegetation, as well as the levels of erosion and sedimentation

Keywords: discharge, velocity, river cross-sectional area
