| description abstract | Most of the available methods for roughness prediction assume that the flow is steady and uniform, and many of them are laboratory-oriented and lack verification with field data. Three existing roughness prediction formulas are tested against measured field data. The data used are for three main alluvial irrigation canals with discharges ranging from 35 to 318 m | |
