Abstract
• Bridges Fluvial Geomorphology and Hydraulic Engineering • Reveals the Morphodynamic Role of Roughness Spacing • Novel Laboratory Analog for Natural Channel Features • High Practical Value for Model Validation and Prediction • Quantitative Framework for Roughness Parameterization Open channel flow, governed by gravity and characterized by a free surface, is critical for applications such as flood control, irrigation, and stormwater management. The Manning formula, with its roughness coefficient ( n ), is a cornerstone for estimating flow velocity and discharge, yet its determination in natural and controlled settings remains complex due to factors like channel geometry and roughness. This study investigates…
