Unified Interior Regions

Maryland

Maryland's water supply comes from streams, rivers, groundwater and reservoirs. Many of these systems flow to the Chesapeake Bay, the Nation's largest estuary. This complex ecosystem has been degraded due to the impact of human-population increase. The MD-DC-DE Water Science Center studies the impacts this has on water quality, habitats and biological communities.

Understanding the Effects of Stormwater Management Practices on Water Quality and Flow

Urban development can have detrimental impacts on streams including altering hydrology, increasing nutrient, sediment, and pollutant loadings, and degrading biological integrity. Stormwater Best Management Practices (BMPs) can be used to mitigate the effects of urban development by retaining large volumes of stormwater runoff and treating runoff to remove pollutants. This project focuses on...

A tale of two coasts: tidal marsh persistence with changing climate and sea-level rise- Karen Thorne

The overall goal of this project is to improve our understanding of the combined effects of inundation, due to sea-level rise and storm surges, and other climate factor on tidal marsh physical and biological processes to provide guidance to natural resource managers to reduce these threats and increase resilience.

Collecting Ecological Data and Models of Living Shoreline Restoration Projects

Developing effective living shoreline restoration projects that can withstand hurricanes and storms requires a better understanding of how restoration structures reduce the impact of wave and current energy on marsh edges in estuaries and bays. Without this knowledge, existing living shoreline projects and adaptive management measures are more likely to fail, decreasing the possibility for...
