Abstract
Environmental hydrodynamics is typically characterized by free-surface hydrostatic flows. Within such a framework a set of simplified models are derived from the Reynolds averaged Navier- Stokes equations under various simplifying assumptions. Numerically, a simple method for the 1D open channel ow is derived first. This method is then extended to the 2Dxz laterally averaged model and to the 2Dxy vertically averaged model. Next, a semi-implicit method for the 3D model is described and discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
