In this talk, results of high-resolution numerical simulations of some
complex flows that are occurring in the area of hydraulic engineering will
be presented. The method of large-eddy simulation is employed to study
details of the flow over rough and porous channel beds, flow in an ozone
contactor and the flow through idealized emergent vegetation. The main
objective of the simulations is to gain insight into physical mechanisms
at play. In particular, flow unsteadiness and coherent turbulence
structures are important contributors to mass and momentum transfer in
open channels. The performed large-eddy simulations allow revealing and
quantifying these coherent structures.
