Selecting Manning’s n Values for 1D HEC-RAS Models
The Manning’s roughness coefficient, which is also commonly referred to as Manning’s n, is an empirical parameter that represents energy loss due to a variety of things such as friction losses, flow separation, turbulence, and very sudden contractions or expansions. Manning’s n values are applied to Manning’s equation, which calculates open channel flow. In HEC-RAS, … Continue reading Selecting Manning’s n Values for 1D HEC-RAS Models
