38 The contours created thus far are for "natural" objects, as against "artificial" objects.
39 The latter classification corresponds to the use of altitude mode for computing the Z-elevation
40 at all points on their surfaces.
42 Natural objects correspond to surfaces whose Z-dimension is determined by a bathymetry/altitude field.
44 Examples of artificial objects are embankments, canals or channels, which will be represented by a constant
45 cross-section, extruded along a line whose altitude could potentially vary.
47 There are two sub-categories of natural objects: "immersible" zones associated to a point cloud of the
48 bathymetry field /altitude type (.xyz or .asc) and "stream" zones which correspond to rivers described
49 by a series of cross profiles. These profiles constitute a bathymetry field on which a specific interpolation
50 method will be applied to calculate the Z-dimension.
52 In this exercise, three immersible zones will be created, defined by a contour and a bathymetry/altitude field:
54 * The minor bed, defined by the *garonne* contour and the bathymetry field *garonne_point_L93*,
56 * The major bed, defined by the contour of the *garonne_point_L93* field and the field itself,
58 * The study domain, defined by its contour, and the *cloud_02* field.
60 The context menu of the *NATURAL OBJECTS* folder is used to create an immersible zone.
62 |createImmersibleZone|
64 The dialog box proposes defining the zone name and selecting the contour and the bathymetry from the drop-down
65 lists of existing objects. The choices must be confirmed with *apply and close* to create the zone.
67 Once created, the colour of the zone can changed using the context menu associated to the object name.
71 Displaying all three zones should provide a view resembling the one below:
75 It may be necessary to re-order the display layers: the *Change Layer* Order option in the context menu
76 of the graphic view permits to set the object order. This setting will be remembered when the study is saved:
80 The context menu associated with each immersible zone contains a *Submersible* parameter that is checked by default
81 (icon pushed in). If the user wants to create an island in the TELEMAC sense, i.e. a non-floodable zone,
82 which will create a hole in the mesh, this parameter has to be unchecked.
