Roughness Spacing in Rigid Open Channels

Abstract
Experiments were conducted in 8 ft wide by 72 ft long adjustable-slope flume; roughness elements consisting of sheet metal baffles were placed on bed of flume at various longitudinal and transverse spacings; data are analyzed in terms of von Karman-Prandtl concepts of turbulent flow near rough boundary; logarithmic flow formulas are developed in which roughness factor is related to size and spacing characteristics of roughness elements.
