High Resolution Field Observations of Shoreward Sediment Transport Within the Wave Bottom Boundary Layer on a Sandy Beach

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract We introduce a data archive containing the first highly resolved profiles of velocity and sediment concentration within the wave bottom boundary layer (WBBL) on a natural sandy beach. Resolution of the thin WBBL was made possible by deployment of a unique “Multi‐Frequency Doppler” (MFDop) bistatic acoustic profiling instrument on an Oregon ...

Mesoscale Shoreline Evolution on a Carbonate Sand Island: Anegada, British Virgin Islands

Journal of Marine Science and Engineering, 2023
Anegada, the easternmost island of the Virgin Islands group (Caribbean Sea), is a low Pleistocene carbonate platform surrounded by Horseshoe Reef, the world’s third-largest fringing reef. The western part of the island consists of an extensive beachridge

The Importance and Mechanics of Near‐Seafloor Oxygenation Events in Shallow Coastal Environments

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Bottom‐water oxygen (O2) possibly constitutes the strongest regulating factor on ecosystem function of the seafloor environment. The conventional view of bottom‐water O2 regulation in temperate regions is a strong seasonal variability imposed by deposition of fresh, labile organic carbon following the spring and fall plankton bloom generating ...

Mega Mounders: Burrowing Talitrids (Megalorchestia spp.) Excavate Large Quantities of Sand on California Beaches

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 9, September 2026.
Abstract High densities of burrowing talitrid amphipods inhabit beaches around the world. This includes California, where densities of more than 1,000 individuals m−2 are regularly recorded. Here, we provide evidence of Megalorchestia spp. excavating up to 10.38 kg dry sand m−2 d−1 on a beach in southern California, one of the highest mounding rates ...

Impact of an extreme storm event on a multiple intertidal barred coastal system

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Extreme storms do not necessarily cause extreme coastal erosion. Integrated DGPS surveys and SWAN nearshore wave modelling reveal that Storm Barra's peak coincided with a low‐tide stage, allowing multiple intertidal bars (MITBs) to dissipate incoming wave energy before it reached Dundrum Bay's shoreline, highlighting the combined role of tidal stage ...

Increasing Frequency of Coastal Erosion Indicated by a Hindcast Model of Storm‐Driven Forcing Calibrated With Beach Stratigraphy

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Beach stratigraphy at North Beach, Sandy Hook, New Jersey is used to calibrate a model of coastal erosion, establish a model‐based erosion threshold, and evaluate how often threshold conditions have been exceeded since 1979 through hindcast analysis.

The Effectiveness of Groin Modifications to Reduce the Impacts of Indian Ocean Dipole (IOD)-induced Port Siltation in Adapting to Climate Change

Journal of the Civil Engineering Forum
Climate anomalies significantly affect coastal hydrodynamics, influencing sediment transport processes. The interaction between waves and currents plays an important role in sediment transport, which is closely related to climate anomalies, particularly

Coastal Processes and Longshore Sediment Transport along Krui Coast, Pesisir Barat of Lampung [PDF]

, 2019
Longshore sediment transport is one of the main factors influencing coastal geomorphology along the Krui Coast, Pesisir Barat of Lampung. Longshore sediment transport is closely related to the longshore current that is generated when waves break ...

Variation in longshore sediment transport under low to moderate energy conditions on barred macrotidal beaches.

, 2012
The aim of this study was to estimate longshore sediment transport on three sandy barred macrotidal beaches of Northern France using sediment traps. Measurements of longshore sediment transport were carried out at several locations across the intertidal ...

Comparison and analysis of different longshore sediment transport formulas

Shui kexue jinzhan
The longshore sediment transport has been intensively investigated in the past nearly one hundred years and numerous formulas have been proposed to predict the longshore sediment transport rate.
