Methods for estimating daily upstream location of the freshwater-saltwater interface along the Maurice and Cohansey Rivers, New Jersey Methods for estimating daily upstream location of the freshwater-saltwater interface along the Maurice and Cohansey Rivers, New Jersey
The Delaware River basin (DRB) provides drinking water to 15 million people in the surrounding area. Water is frequently withdrawn from the freshwater reaches of streams, above head of tide, in the DRB for use as public drinking water. During extended periods of low flow, saltwater can move upstream, which can threaten drinking-water supplies in the basin. Due to spatial patterns in...

Monitoring of wave, current, and sediment dynamics along the Fog Point Living Shoreline, Glenn Martin National Wildlife Refuge, Maryland Monitoring of wave, current, and sediment dynamics along the Fog Point Living Shoreline, Glenn Martin National Wildlife Refuge, Maryland
Living shorelines with salt marsh species, rock breakwaters, and sand nourishment were built along the coastal areas in the Glenn Martin National Wildlife Refuge, Maryland, in 2016 in response to Hurricane Sandy (2012). The Fog Point living shoreline at Glenn Martin National Wildlife Refuge was designed with the “headland - breakwater - embayment” pattern. Scientists from the U.S...

Field observations and long short-term memory modeling of spectral wave evolution at living shorelines in Chesapeake Bay, USA Field observations and long short-term memory modeling of spectral wave evolution at living shorelines in Chesapeake Bay, USA
Living shorelines as a nature-based solution for climate change adaptation were constructed in many places around the world. The success of this type of projects requires long-term monitoring for adaptive management. The paper presents a novel framework leveraging scientific machine learning methods for accurate and rapid prediction of long-term hydrodynamic forcing impacting living...

Modeling surface wave dynamics in upper Delaware Bay with living shorelines Modeling surface wave dynamics in upper Delaware Bay with living shorelines
Living shorelines gain increasing attention because they stabilize shorelines and reduce erosion. This study leverages physics-based models and bagged regression tree (BRT) machine learning algorithm to simulate wave dynamics at a living shoreline composed of constructed oyster reefs (CORs) in upper Delaware Bay. The physics-based models consist of coupled Delft3D-FLOW and SWAN in four...

Monitoring of wave, current, and sediment dynamics along the Chincoteague living shoreline, Virginia Monitoring of wave, current, and sediment dynamics along the Chincoteague living shoreline, Virginia
Nature-based features, also called living shorelines, are increasingly applied in coastal protection and restoration. However, the processes and mechanisms (feedbacks and interactions) of wave attenuation, current velocity change, and sediment deposition and erosion along the living shoreline remain unclear, thus limiting the adaptive management of living shoreline restoration projects...

Field observations of wind waves in Upper Delaware Bay with living shorelines Field observations of wind waves in Upper Delaware Bay with living shorelines
Constructed oyster reefs (CORs) provide shore protections and habitats for fish and shellfish communities via wave energy attenuation. However, the processes and mechanism of CORs on wave attenuation remain unclear, thus limiting the effective assessment of CORs for shoreline protection. This paper presents results of a field investigation on wave characteristics and wave spectral...
