What is Rugosity Coefficient ?

The rugosity coefficient, often represented by Manning's n, quantifies the roughness or irregularity of a channel or pipe's interior surface, affecting fluid flow. This coefficient influences the velocity, discharge, and energy loss in hydraulic systems. It varies based on material, surface texture, and the presence of obstructions. Accurate determination of the rugosity coefficient is essential for predicting flow behavior, designing efficient water conveyance systems, and ensuring proper drainage or sewage management.
