dissipation from bottom friction, wave breaking, nonlinear amplitude dispersion, and harbor entrance
losses. CGWAVE is a finite element model that is interfaced with the Department of Defense
Surface-Water Modeling System (SMS) for graphics and efficient implementation (pre- and post-
processing).
Figure 2 shows the orientation of the CGWAVE model domain relative to Tedious Creek and the
adjacent countryside. The brown line represents the model boundaries for the harbor and the blue
line the ocean or seaward water boundary. The CGWAVE model requires a minimum of 6 to
10 elements per wavelength. Since the harbor area is large and shallow and wave periods as small as
