【 摘 要 】

Nutrient and sediment pollution are important issues in Baltimore Harbor. The poor water quality has affected human activities and lives in the Harbor. This report applied Chesapeake Bay Phase 5.3 Watershed Model output to find source apportionment in Baltimore Harbor, and then WRTDS model and point source data were used to estimate total loadings delivered to the Harbor from 1999-2013. The changes and contributions of point source and CSO over years were also estimated. It was concluded that point source was the major source in TN and TP loadings, but not very significant in TSS loading. CSO from Patapsco CSS did not take large portion in river inputs, but more complete data will be needed to better analyze CSO pollution in the future.
