Example:
For the following sections:
The section heights are defined as follows:
 H1= - 0.5 m
 H2= - 0.2 m
 H3= 1.2 m

H4= 1.9 m
The elevations may be negative, null or positive depending on the H0 chosen.
The widths meanwhile are defined with regard to a vertical plane
As for the heights, the widths may be negative, null or positive with regard to this plane.
Comments:
 The highest point must be greater than the maximum foreseeable water level. If the water exceeds
this height, the entire area located above this last point is not taken into account.
 For rather complex sections (e.g. semi-circular outfall sewer with cunette), it is important to
surround the discontinuities with two elevations close together.
 It is not compulsory to define 20 pairs of points. The widths of the unused points may be set to 0.
