Vertical Roughness in a Pipe In InfoSWMM
Vertical Roughness Threshold - The Vertical Roughness Threshold is a fraction and the Threshold depth calculated from this fraction will be the Vertical Roughness Threshold Fraction * Maximum depth. If the Maximum depth is 3 meters and the Vertical Roughness Threshold is 0.5 then the dividing depth is 1.5 meters Vertical Roughness - The lower or higher link roughness is entered as the Vertical Roughness value Vertical Roughness in a Pipe In InfoSWMM
