Chesapeake Bay Watershed Model Application and Calculation of Nutrient and211 Sediment Loadings. Appendix F: Point Source Loadings

摘要

Appendix F documents in detail the Phase IV Chesapeake Bay Watershed Model point211u001esource nutrient data assimilation process for the facilities located in signatory 211u001eand non-signatory jurisdictions of the Chesapeake Bay Watershed. This document 211u001eincludes a description of the data sources, the methods of assimilation, types of 211u001eanalysis performed to determine nutrient reduction estimates, and trends in 211u001enutrient loadings discharged to the Chesapeake Bay Watershed. The Phase IV 211u001eWatershed Model Point Source Database includes information for approximately 612 211u001e(the exact number varying depending on the year) active industrial, municipal, 211u001eand federal facilities discharging directly to surface waters within the 211u001eChesapeake Bay watershed from all signatory and non-jurisdictions including: New 211u001eYork, Pennsylvania, Maryland, Delaware, District of Columbia, Virginia and West 211u001eVirginia. Facility information, and flow and loading data are included for each 211u001eof the 612 facilities for the years 1985 through 1996, 2000, Tributary Strategy 211u001eImplementation (which is expected to occur after the year 2000) and additional 211u001enutrient reduction scenarios. The following flow and loading parameters are 211u001eincluded: flow, total nitrogen, nitrate, organic nitrogen, total phosphorus, 211u001ephosphate, organic phosphorous, biochemical oxygen demand, and dissolved oxygen.
