The HYDRO module enables bathymetry file types that have .xyz or .asc extensions to be imported.
whereas the .asc files are formatted in a Cartesian x, y grid structure. The .asc files contain a header
which lists the number of lines and columns, the coordinates of the south western corner and the cell-size in x and in y,
below which is a matrix of the z altitude values. It is also possible to import bathymetries contained
-in SinusX-format files, as will be described later.

-The *cloud_02.xyz* file is an extract of IGN data on a regular grid with one point every 75 m, freely available.

The *garonne_point_L93.xyz* file corresponds to an earlier study, covers the major bed of the river over the region
-and is potentially more precise than the previous file, at least on the minor bed.

These files are imported using the context menu of the *BATHYMETRIES* folder in the SALOME study tree.
The import dialog box permits the user to select the file to be imported and to change its name in the study tree.
-The import instructions are confirmed by clicking on the *Apply and Close* button.
