Surface roughness is a measure of finely spaced surface irregularities. Surface roughness is the second component of Surface Texture. Surface roughness is usually what machinists refer to when talking about "surface finish.". When talking about all three characteristics, they may use the term "Surface Texture" more properly. Waviness.

Each manufacturing process is designed to produce a usable surface finish. Each process has an expected surface finish tolerance. For example, broaching offers an expected surface roughness of 0.8-3.2μm. In some cases, a secondary process like grinding or polishing is needed to reduce surface roughness.

The roughness coefficient value designated in the BRP (0.033) is approximately 72.5% and 25% smaller than those estimated in this study for discharges of 37 m3/s and 1 000 m3/s, respectively. Such a small value may give rise to relatively large errors when used for calculation of water depth and velocity.
