Flow resistance equations for mountain rivers

Abstract: Three models of flow resistance (a Keulegan-type logarithmic law and two models developed for large-scale roughness conditions: the full logarithmic law and a model based on an inflectional velocity profile) were calibrated, validated and compared using an extensive database (N = 1,533) from rivers and flumes, representative of a wide hydraulic and geomorphologic range in the field of gravel-bed and mountain channels. It is preferable to apply the model based on an inflectional velocity profile in the relative… Show more

“…So far, various friction models have been proposed and used in practical applications, which have been derived from the theory of fluid mechanics (e.g., Bates et al 2005;Cheng 2008;López et al 2009;Nepf 2012;Özgen et al 2015). However, so far, this theoretical knowledge has not yet been exploited for improving hydrodynamic modeling.…”
