“…The seasonal climate generally involves cool winters with occasional heavy rainfalls from thunderstorms. Average annual precipitation is 137 cm (Fontaine, 1991). As will be shown later, the month with highest precipitation is usually December, and there is frequently a secondary peak in precipitation in March.…”

“…This work documents a portion of a project that was started at the Oak Ridge National Laboratory in order to evaluate the magnitude of contaminated sediment transport during floods at the White Oak Creek (WOC) drainage system, and to develop strategies for controlling off-site transport. This project includes a data collection program to establish a conceptual model of contaminated sediment movement in WOC, calibration of a conceptual model, and generation of a database that will be used in the future to assess the effectiveness of completed site remediation (Fontaine, 1991).…”

A complex watershed‐scale water quality simulation model, the Hydrological Simulation Program‐FORTRAN (HSPF) model, was calibrated for a 16 km2 catchment. The simulation step size was 0.33 hours with predicted and recorded hydrologic flows compared on an annual and monthly basis during a total calibration period of four years. Unguided numerical optimization when applied alone did not yield a model parameter set with acceptable predictive capability; instead, it was necessary to apply a critical process that included sensitivity analysis, numerical optimization, and testing of derived model parameter sets to evaluate their performance for periods other than those for which they were determined. Using this critical calibration process, the model was proven to have significant predictive capability. Numerical optimization is an aid for model calibration, but it must not be used blindly.

“…Hydrologic data used for this analysis included hourly precipitation, hourly streamflow, and daily evaporation collected at several locations within the catchment (Borders and Frederick, 1993). A threeyear field data collection program specifically designed for the simulation of contaminated sediment was used to measure sediment transport and the concentration of Cs137 on sediment during normal and flood streamfiow conditions (Fontaine, 1991). Manual and automatic samples were collected at seven sites in the catchment at 30-minute intervals using standard methods from Edwards and Glysson (1988).…”

A simulation analysis of contaminated sediment transport involves model selection, data collection, model calibration and verification, and evaluation of uncertainty in the results. Sensitivity analyses provide information to address these issues at several stages of the investigation. A sensitivity analysis of simulated contaminated sediment transport is used to identify the most sensitive output variables and the parameters most responsible for the output variable sensitivity. The output variables included are streamflow and the flux of sediment and Cs137. The sensitivities of these variables are measured at the field and intermediate scales, for flood and normal flow conditions, using the HSPF computer model. A sensitivity index was used to summarize and compare the results of a large number of output variables and parameters. An extensive database was developed to calibrate the model and conduct the sensitivity analysis on a 6.2 mi2 catchment in eastern Tennessee. The fluxes of sediment and Cs137 were more sensitive than streamflow to changes in parameters for both flood and normal flow conditions. The relative significance of specific parameters on output variable sensitivity varied according to the type of flow condition and the location in the catchment. An implications section illustrates how sensitivity analysis results can help with model selection, planning data collection, calibration, and uncertainty analysis.

“…M e r a formal selection process, the Hydrological Simulation PackageFortran (HSPF) model was selected to simulate the water, sediment, and contaminant transport in the WOC watershed because it is comprehensive with respect to hydrology and contaminant mobilization and transport mechanisms (Fontaine 1991). Subsequently, the model was used for the following purposes:…”
