2DH numerical hydrodynamic models


Hydromorphological models

Basic principles

Fundamental equations for conservation of water mass and water flow momentum, spatially averaged over water depth (hence “H” for horizontal plane in “2DH”) and 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
