Webb8 apr. 2010 · A procedure for determining Manning roughness coefficient n equation involves use of a base value, n1, for the roughness coefficient and addition of modifiers, n2, n3, n4, n5, & n6, based on the nature of several channel characteristics. The roughness coefficient value is needed for uniform open channel flow calculations, but determining … WebbEcology: As a measure of complexity, rugosity is presumed to be an indicator of the amount of available habitat available for colonization by benthic organisms (those attached to the seafloor), and shelter and foraging area for mobile organisms.
