2004 Storms Simulation Results

A series of simulations of storm events sampled in 2004 were conducted to evaluate model performance by comparing to field data. Output from HSPF was using to simulate the runoff for each storm event and the estuarine CH3D-FC model was run to simulate the tides, circulation conditions, and FC inputs occurring during the sampling period starting from 24 hours before the storm event and ending 24 hours after the storm event. CH3D-FC was used to simulate the 25th percentile, geomean, and 75th percentile for the FC loading concentrations. The model output a time series of FC concentrations for each of the loading concentrations simulated. The observed data from each sampling station were compared to the simulated data from the corresponding (or nearest) model grid. The simulated and observed salinity at each station were also compared.

Three specific sampling events were simulated. Output is available from the 94x105 and 91x96 grids:

The verification results showed good agreement between the modeled and observed data.
