Can a 3D-Numerical Model be a Substitute to a Physical Model in Estimating Parameters of 1D-Confluence Models?
(Universidade do Porto, Faculdade de Engenharia, 2014)
A possibility of using a 3D-numerical model instead of a more expensive physical one for estimation of parameters in 1D-confluence models is considered. A set of existing experimental data from 90º confluence is used for ...
Effects of bed material grain-size distribution on bed morphology at a river confluence - numerical study
(EGU (European Geophysical Union), 2017)
River confluences play an important role in the drainage of a catchment and transport of sediments and pollutants within this area. Riverbed morphology at these important nodes of the river drainage network might be very ...
Hydrodynamics of 90o concordant beds’ confluences of straight-channels with unequal channel widths
(EGU (European Geophysical Union), 2017)
With the exception of confluences of large alluvial rivers, tributary channel is usually narrower that the channel of the main-river. hydrodynamics of confluences of equal width channels has been thoroughly studied using ...
