Friction modeling of flood flow simulations

V Bellos, I Nalbantis, G Tsakiris - Journal of Hydraulic Engineering, 2018 - ascelibrary.org
A new, three-parameter friction model at the boundaries of free surface flow is proposed.
The model is valid for all flow and roughness characteristics and it is proposed to replace the …
