Annual estimated effect of best management practice implementation on water quality in the Chesapeake Bay watershed from 1985 to 2014

This metadata record documents a comma-delimited table representing scenario output from the Chesapeake Bay Program Phase 5.3.2 Watershed Model. The annual effect of best management practices (BMP) on water quality in the Chesapeake Bay Watershed (CBWS) is estimated through a series of model scenarios. The model output data tables for each year from 1985 to 2014 are included with estimated mass of nitrogen, phosphorus, and sediment. Each year has an output table for a “Progress” scenario, which is a model run with all BMPs active, and a “No Action” scenario, which is a model run with all BMPs deactivated. Model output is provided at the Watershed Model land-river segment scale.
