Figure 2.4 shows the ability of a TIN to conform to complex terrain and identify channel features.

Delauney triangulation, based on the concept of maximizing the minimum angle of all triangles produced by connector lines to their nearest neighbor points,
is most often used to generate TINs. smoothness and continuity of the surface
Breaklines are used to control the such as streamlines or roads by forcing
triangles to conform to these lines. For this reason, TINs are generally surface representation of stream channels in hydraulic modeling since land surface details may accurately be represented (Lee et al., 1980).
