TRIM2D

Cooperative effort of USGS & SPAWAR, 1996
PC and UNIX

TRIM2D is a 2-dimensional, depth-averaged, finite-difference hydrodynamic model for simulating inland water flows governed by tidal, wind and riverine inputs. The model uses a high resolution uniform grid to solve the incompressible Navier-Stokes equations, and the method is computationally very stable. Simulation output includes water currents, water surface elevation, salinity profiles, and the distribution of any released contaminants.

Enhancements to the USGS model have been made by SPAWAR and include the addition of fuel/oil spill simulations, sediment transport, and outfall dilution. SPAWAR has also developed extensive pre- and post processing visualization routines. Post processing capabilities include both single view and animation of the simulation results.

Here are some sample outputs from this model (animations open in a separate window):

Total load from private boats only. Click here or on the image for a time-series animation of the model output. A much larger (2.1MB) and higher quality version is available here.
