#### 1. Quick description
of Telemac

Telemac-2d was developed by the National Hydraulic Laboratory (LNH)
of the research and developement center of EDF. This software aims at solve
the Saint-Venant equations (Shallow eqautions) on a two dimentionnal grid.
Its main applications are computations on free surface flow. It can takes
into account:

- large wave propagation
- friction
- Coriolis force
- meteorological phenomenon
- Turbulence
- Subcritical and supercritical flows
- Influence of the temperature and the salinity...

#### 2. Description of
the simulated case

We consired a channel with a crectangular cross-section which is 20
m long and 10 m wide. At mid-lenght a hump is created at the channel bottom.
This hump has a height of 0.2 m and has a parabolic shape.

The lateral walls of the channel are supposed to shear-stress free whereas
at the bottom we will consider both the case with or without shear-stress.
The are two open boundaries at the inflow and the outflow where different
boundary conditions have to be imposed depending on the flow regime.
