subbasins in ecoregions common to the Tar-Pamlico Basin.
Consequently, we used the results from the Chesapeake Bay Watershed Model
from these areas for our estimates of conservation
effectiveness (Figure 2-
The parameters used in the Chesapeake Bay Watershed Model represent a
synthesis of the results of over 30 research studies conducted in the basin.
However, Camacho (1990)
thatthese were still insufficient to accurately
characterize nutrient reduction efficiencies in both groundwater and surface
waters for some regions of the Chesapeake basin. Consequently, the
professional judgment of the modelers played a role in determining the model
input parameters. (An overview of the Chesapeake Bay Watershed Model is
included in Appendix 2.)
