Watching the Tide Come In: Environmental Thermography Meets Tidal Wetland Hydrology

Written on: May 18th, 2018 in Wetland Assessments

by Tom McKenna, Delaware Geological Survey, University of Delaware Working in tidal wetlands, we all know to watch the tide both for safety, sampling, and science reasons. But what do we really know about how tidal wetlands are inundated? The dynamics of the ebbing and flooding tide in deep (> 1 meter) tidal channels is […]

When Saltwater Intrusion Meets Freshwater Wetlands…

Written on: March 7th, 2018 in Wetland Assessments

by Erin Dorset, DNREC Wetland Monitoring & Assessment Program As you might imagine, sea level rise can increase water levels and cause more flooding. As that happens, salt water starts to move further inland. It may start to creep into freshwater areas through a process called saltwater intrusion. Higher waters can endanger coastal communities, while […]

Well Monitoring: Can riverine wetlands reduce downstream flooding?

Written on: March 7th, 2018 in Wetland Assessments

By Kenny Smith, DNREC, Wetland Monitoring & Assessment Program Wetlands provide many vital benefits to the State of Delaware, like habitat for all kinds of plants and animals, improved water quality, and erosion control. Another benefit that wetlands provide is flood control. Wetlands have the ability to collect and store storm waters and lessen flooding […]

“Groundwater outcrops”: Wetlands associated with springs and seeps

Written on: December 12th, 2017 in Wetland Assessments

Guest Writer: Tom McKenna, University of Delaware Groundwater discharge areas are common hydrologic features in Delaware’s Piedmont Province, located in hilly northern New Castle County. Discharge occurs as springs or seeps. (A seep can be described as simply a spring with discharge through the very small openings between soil or sediment grains. In reality it […]

Tidal Freshwater Wetlands

Written on: September 19th, 2017 in Wetland Assessments

You may already be aware that saltwater wetlands are influenced by ocean tides, and that freshwater wetlands located further inland are not influenced by tides. But, did you know that there are freshwater wetlands that are actually still influenced by the ocean’s tides? These wetlands, commonly called tidal freshwater wetlands, are in some ways similar […]

Blue Carbon – a benefit to protecting tidal wetlands

Written on: September 19th, 2017 in Wetland Assessments

Guest Writer: Kari St.Laurent, Delaware National Estuarine Research Reserve Wetlands are more than just a beautiful photo opportunity. If you are a reader of this blog, you are probably aware that tidal wetlands can protect shorelines from storm surge, reduce nutrients, and provide habitat for critters like shellfish, crabs, and fish. These benefits are collectively […]

Keeping an Eye on the Rising Tide: SSIM

Written on: May 24th, 2017 in Wetland Assessments

Coastal wetlands are a hallmark feature of the Delaware’s Bayshore, making up about 23% of all wetland types in the state. Because of the many beneficial services these wetlands provide, such as wave energy reduction, the survival of coastal wetlands is an important part of protecting our seaside communities from threats associated with the changing […]

Delaware Participates in the National Wetland Condition Assessment

Written on: September 7th, 2016 in Wetland Assessments

Did you know that 50% of wetlands in our coastal plains ecoregion are in good condition?  The U.S. Environmental Protection Agency (EPA) organized the National Wetland Condition Assessment (NWCA) in 2011 to get these data, and now our Program (Wetland Monitoring & Assessment Program) is again helping to assess more of Delaware’s wetlands to contribute to the 2016 NWCA.
