Abstract: Coastal environments are characterized by a variety of sediment deposits with highly diverse geotechnical properties. Particularly in energetic coastal environments, sediment type and properties may vary on small spatiotemporal ...

Abstract: The strength of partially saturated sand is critical for addressing engineering challenges such as beach trafficability or coastal erosion. Mapping strength remotely would allow for surficial geotechnical characterization ...

Abstract: Geotechnical sediment properties, morphological change, and hydrodynamics were measured as part of the During Nearshore Event Experiment (DUNEX) in October 2021 at the sandy Atlantic side beach in Duck, North Carolina. In ...

Abstract: This study investigates the geotechnical characteristics of a soft tidal mudflat in the Great Bay Estuary, New Hampshire. Laboratory testing of surficial sediment samples of the upper 10 cm and field observations from ...

Abstract: In situ pore pressure dissipation in soil primarily depends on the coefficient of consolidation and permeability of the soil. This study represents an initial effort to investigate pore pressure dissipation induced by ...

Abstract: Scour holes around slender piles were measured in areas inundated during Hurricane Michael and were compared with scour hole depths estimated from existing scour prediction equations. Despite testing a wide range of feasible ...

Abstract: Colocated sediment pore pressures at depths of approximately 0.02 and 0.22 m below the sand surface and near-bed water velocities were measured for approximately 2 weeks in approximately 1 m mean water depth on an ocean ...

Abstract: Oysters are hypothesized to affect the shear strength of nearby surficial seafloor sediment as fragments of oyster shells (shell hash) are typically more angular relative to sand particles alone, among other differences. ...

Abstract: Two in situ geotechnical surveys were undertaken in Sydney Harbour, Nova Scotia, Canada, following the dredging and relocation of 4.2 million m3 of sediment from the shipping channel during the fall and winter of late 2011 ...
