LONG TERM SIMULATION OF TRANSPORT USING SPATIALLY AND TEMPORALLY AGGREGATED MODELS

Simulations of algal blooms over planning periods of 20 years or more are desirable for the management of catchments surrounding significant bodies of water. It is a massive computational task to simulate transport and water quality processes coupled with 3-D hydrodynamic models at their grid-scales. Box models, in which transport is approximated between much larger spatial regions and over longer timesteps have been widely used. Transport is determined by measurement or simple simulation techniques. This project compares the accuracy of simulations of simple ecosystems in fully coupled models with box models at various resolutions whose transport is determined by integration of the transport in the high resolution model. The project compares results from a water quality model using the integrated transport process with a full resolution model, which is incorporated into the Princeton Ocean Model (POM) at the scale of the hydrodynamic grid. A supercomputer is used for multi-year simulations using the model integrated with POM.
