Map: Chesapeake Bay Watershed Model: Phase 5 Modeling Segments

n order to divide the model domain into county based land segments, a finer segmented river reach network and associated watersheds.This data set is an ArcGIS shapefile depicting land segments in the Chesapeake Bay Watershed and adjacent states of New York, Pennsylvania, Maryland, West Virginia, Delaware, Virginia as well as North Carolina and Tennessee (not shown). Land segmentation was based on county boundaries represented by a 1:100,000-scale digital dataset. Fifty of the 254 counties and incorporated cities in the model region were divided on the basis of physiography and topography, producing a total of 310 land segments. The data are projected to the UTM grid coordinate system - Zone 18 NAD83. Land and watersheds segments were intersected to create land-watershed segments for the model. The land segments are to be used with the Chesapeake Bay Regional Watershed Model to represent the county political boundaries and areas of differing physiography and topography in the study area.
