The 3DD Computational Marine and Freshwater Laboratory consists of a

series of coupled numerical models to simulate physical and biologicalprocesses in marine and freshwater environments. The models are:

1.1. 3DD3DD :: 2 or 3-dimensional flows, short-wave and ocean/atmosphereheat transfer

2. POL3DD2. POL3DD :: 3-dimensional dispersal

3. WGEN3. WGEN :: Estuary wave climate4. WBEND4. WBEND :: Refraction of monochromatic and spectral waves

5. 2DBEACH5. 2DBEACH :: Beach circulation and sediment transport

6. GENIUS6. GENIUS :: Sedimentation around coastal structures

77.. Support ManagerSupport Manager :: Routines for preparation of input files, extraction of resultsfrom the model output file and for graphics.

88.. PLOT3DDPLOT3DD :: Matlab graphical routines for plotting the model results aresophisticated and allow a broad range of output styles.
