06. Constant vs. Varrying Roughness The Manning Equation can be applied using three methods, including the Design Method, the Lanfear-Coll Method, and the Stevens-Schutzbach Method. The roughness coefficient used in […]
05. Manning Equation Comparison The Manning Equation can be applied using three methods, but which method should be used? Laboratory results have shown that these methods provide similar results under […]
04. Stevens-Schutzbach Method The Stevens-Schutzbach Method is an iterative regression technique used to fit the Manning Equation to flow monitoring data. This method can be applied to data obtained under […]
03. Lanfear-Coll Method The Lanfear-Coll Method uses a regression technique to fit the Manning Equation to flow monitoring data. This method can be applied to data obtained under uniform flow […]
02. Design Method The Design Method is a traditional use of the Manning Equation and requires information regarding the roughness coefficient (n) and the pipe slope (S). These values are […]
