Hydrodynamic controls on multiple tidal inlet persistence
The importance of the persistence of multiple inlets in coastal systems is fundamental for issues such as water quality, navigability, and beach/barrier stability. In long embayments, having extended residence times, the stability of multiple inlets can be important for more efficient flushing and …

Hydrodynamics of a multiple tidal inlet system : Katama Bay, Martha’s Vineyard, MA
… of tides, waves, bay bathymetry, and changing inlet geometry on the hydrodynamics of the multiple-inlet Katama system, Martha’s Vineyard, MA. Momentum fluxes from breaking waves drive water into the inlet, nearly stopping the 2 m/s ebb currents during a hurricane. The evolving morphology of …

GEOLOGICAL LEGACY OF A HISTORIC WAVE-DOMINATED TIDAL INLET, CENTRAL NEW JERSEY
Tidal inlets are among the most dynamic of landforms and leave a geological legacy within coastal barrier systems. Background document analysis of the historic Cranbury Inlet (also known as New or Cranbury Inlet, New Jersey, USA), suggests much debate surrounding the years of its opening and a …

WAVE AND CURRENT OBSERVATIONS IN A TIDAL INLET USING GPS DRIFTER BUOYS
… as the wave field propagated over the ebb-tidal shoal and at the entrance to the channel, in the presence of a strong opposing ebb current, as expected. Inside the channel, strong dissipation of high frequency wind waves was observed in the opposing current.

Sand transport in northern Venice Lagoon through the tidal inlet of Lido
… of sand has been investigated around Lido Inlet, the largest of<br/>three tidal inlets in Venice Lagoon, Italy. Morphological analysis has established the presence<br/>of an ebb-tidal delta extending from the mouth of Lido Inlet as well as other features typical<br/>of tidal inlets. The …

Long and Short-Term Morphologic Evolution and Stratigraphic Architecture of a Transgressive Tidal Inlet, Little Pass Timbalier, Louisiana
… barrier island shorelines can be attributed to tidal inlet processes, and therefore an understanding of these processes is important to effectively manage barrier systems. High rates of relative sea-level rise within the Mississippi River delta plain have resulted in rapid landwardmigration of …

Exploring the Influence of Diurnal Forcing on Tidal Inlet Exchange and the Impact on the movement of Oxygen Depleted Waters in the Mississippi Sound and Bight Region
<p>A small yet notable hypoxic event manifests east of the Birdfoot Delta in the Mississippi Sound and Bight (MSAB). The shallow shelf environment of the MSAB is affected by a host of complex physical interactions and separating the influences of each process is difficult to accomplish with …

Sedimentology, Stratigraphy and Reservoir Characterization of the Middle Jurassic Upper Shaunavon Member in Southwestern Saskatchewan
… within a marginal marine environment under tidal and brackish water influences. Facies Association 1 has tidal indicators such as inclined heterolithic stratification, channel lags and coals. Brackish influences are indicated by low-diversity, diminutive trace fossils as well as synaresis …

Numerical Simulation Of The Atmospheric Boundary Layer Over Complex Topography: A Modern Approach To A Classical Problem
… Then, a full scale simulation of the ABL over a tidal inlet was conducted. It was found that the resolved topography of the Earth’s surface had a significant effect on the flow field. Furthermore, it was found that the results from LES are more accurate than mesoscale simulations. Lastly, it was …

Biophysical coupling between turbulence, veliger behavior, and larval supply
… affects larval supply in a turbulent coastal inlet. Gastropod larvae retract their velums and sink rapidly in strong turbulence. Turbulence-induced sinking would be an adaptive behavior if it resulted in increased larval supply and enhanced settlement in suitable coastal habitats. In …

Hydrodynamic and sediment transport numerical modelling and applications at Tairua Estuary, New Zealand
… Observations and numerical modelling showed the tidal wave was distorted as it propagated into the Tairua Estuary, becoming increasingly asymmetrical with distance from the entrance. The tidal wave underwent more distortion during spring tides than during neap tides, resulting in the influx of …

The hydrodynamic evolution of the Maketū Estuary after the re-diversion of the Kaituna River
… modifications to the river channels and estuary tidal inlet. This has resulted in estuarine degradation, as is a common issue worldwide. Globally different approaches to estuary restoration have aimed at mitigating the adverse impacts of estuarine degradation. However, there are still gaps in …

Mapping and Modeling the Seattle Fault Tsunami Inundation in Puget Sound
… the marsh stratigraphy near the modern day tidal inlet of Deer Lagoon, a site that has been greatly altered in modern times though the construction of dikes and building of infrastructure. I correlated the deposit to the last Seattle fault rupture based on radiocarbon dating of organic …

Hydrodynamics, sediment transport and morphodynamics at inlets and river mouths: a numerical investigation
Inlets and river mouths are among the most important coastal zones in terms of their economic, ecological and societal values. However, our current predictive capability on the hydrodynamics, sediment delivery and morphological evolution of inlets and river mouths remains qualitative. The …
