Telemac2d iteratively solves the depth-averaged Navier-Stokes equations (i.e., the Shallow water equations). The Telemac2d tutorials in this eBook use the SELAFIN (*.slf) and Conlim boundary condition (*.cli) files that result from the TELEMAC pre-processing tutorial and the descriptions refer to the Telemac2d manual.

The steady 2d tutorial is the baseline for almost all other TELEMAC-related chapters in this eBook. On top, the unsteady 2d tutorial features the adaption of quasi-steady (near-census unsteady) flow conditions, which is important, for instance, for modeling a flood hydrograph.

Beyond hydrodynamic models, Sediment transport (i.e., morphodynamics) can be modeled using the Gaia module in a TELEMAC simulation. The necessary coupling of hydrodynamics and morphodynamics is described in detail and in general for Selafin-based TELEMAC models in the Gaia chapter.
