Geographic Isolation Scenarios

Geographic Isolation Scenarios

Purpose

• Understand which basins affect which areas of the bay and by how much

Procedure

• Set the Susquehanna at Tier 3 loads and all other watersheds at 2000 levels

• Record the relative change in attainment for each criterion and designated use area

• Repeat for each basin

Progress

• All basins completed

• Results are provisional

Other Considerations

• Final criteria curves not implemented

• Final model applications areas not decided

• Final designated use boundaries and clarity depths not decided

• Problem with the interpolator
