Chesapeake Bay Watershed Model Application and Calculation of Nutrient andSediment Loadings. Appendix A. Phase 4 Chesapeake Bay Watershed; Model Hydrology Calibration Results

摘要

Appendix A documents in detail the Phase IV Watershed Model hydrologycalibration. The results are presented as plots and statistical tables that compare the simulated and observed flows for the 8 years of calibration (1984-1991) for 17 flow calibration stations of the Chesapeake Bay. Specifically, this appendix includes: (1) Observed and Simulated Flows; (2) Actual Error of the Flow; (3) Observed and Simulated Cumulative Flows; (4) Actual Error versus Perentile Sample Population; (5) Paired Frequency Distribution of Simulated and Observed Data versus Percentile of Population; and (6) Scatter Plot and Regression of Simulated versus Observed versus Observed with Ideal Line. The appendix also contains: (1) Comparison of Annual Total Observed and Simulated Flows; (2) Comparison of Daily and Average Monthly Total Flow Observed and Simulated Regressions; and (3) Average Seasonal Regressions. Regression statistics include r-squared, intercept, and slope statistics for the entire data set, on an annual basis, on a seasonal basis.
