Stream A has a gradient of 0.0015 and a length of 80 km. Stream B has a gradient of 0.001 and a length of 120 km. Both streams have the same cross‑sectional area and Manning's roughness coefficient \(n = 0.035\). Using Manning's equation \( V = \frac{1}{n} R^{2/3} S^{1/2} \) (where \(R\) is the hydraulic radius, the same for both streams), which stream is expected to have the higher average flow velocity?
