3D numerical hydrodynamic models


Hydromorphological models

Basic principles

Fundamental equations for conservation of water mass and water flow momentum, time-averaged over all turbulent fluctuations (RANS = Reynolds Averaged Navier-Stokes equation) or time-averaged over only the smaller turbulent fluctuations (LES = Large Eddy Simulation)


Flow velocities, water depths, water levels, flow shear stresses
