An advisory committee has recommended that the Chesapeake Bay Program’s Watershed Model be adjusted to better account for the landscape’s influence on watershed health.
Whether it is a riparian forest buffer that can trap sediment before it flows into a stream or a wetland that can filter nutrient pollution along the edge of a creek or river, the landscape that surrounds a waterway can impact that waterway’s health.
In a report released this week, experts from the Scientific and Technical Advisory Committee (STAC) state that adjusting the Watershed Model to better simulate the influence of riparian forests, forested floodplains and other wetlands would improve the model’s accuracy and allow managers to better direct conservation funds toward those landscapes that most benefit water quality.
The Watershed Model is used by Chesapeake Bay Program partners and stakeholders to estimate the amount of nutrients and sediment reaching the Bay.
