Wave and Longshore Transport Studies on Lake Pontchartrain
… heights, wave periods and long-shore sediment transport in 10 degree directional bins along the shoreline of the Lake. This model can be used as an effective tool for planning, construction and maintenance of beaches along the shores of Lake Pontchartrain.

Response of the Texas coast to global change: Geologic versus historic timescales
… trapping sand of that would otherwise be in the longshore transport system. Coastal sand budgets are derived to put geologic events (such as hurricanes and erosion) into context. Sand budgets often use engineering assumptions to establish sand transport within a coastal system. However, a …

Late Quaternary marine deposits, offshore central Texas: Processes controlling geometry, distribution, and preservation potential
… sea-level fall. High sediment supply from longshore transport preserved thick, aerially extensive shoreline deposits. Fluvial incision varied significantly during lowstand Stage 2. As the rate of base-level fall increased from Stage 3 to 2, low sediment supply rivers incised narrow, shallow …

From Representative Period Selection to Process‐Based Sediment Dynamics
… tides, waves and wind jointly govern sediment transport. Despite its ecological and morphological significance, the region remains comparatively understudied, and its typical residual and storm-driven sediment pathways are poorly understood. This thesis develops an integrated, process-based …

Sediment dynamics on Wemyss beach, South Fife
… complex environment in which to examine sediment transport. The use of tracers revealed that low density coal pebbles were 'rejected' from the bedload layer of ironstone and sandstone pebbles, and were transported to extreme distances alongshore and potentially offshore. Whereas, the high specific …

Holocene Geology and Migration of a Low-Profile Barrier Island System, Metompkin Island, Virginia
… along southern Metompkin Island disrupted longshore sediment transport, increased the rate of shoreline recession, and resulted in differential rates of retreat associated with an abrupt break in backbarrier morphology. By 1981, a 400 m offset had formed at a position midway along Metompkin …

Freshwater Transport on the Continental Shelf of the Southeastern United States
… found to be driven by four major components: (1) longshore wind, (2) longshore pressure gradient, (3) onshore wind and (4) cross-shelf density gradient including freshwater influx. Wind stress was the primary driving force for shelf circulation Southward wind stress produced a southward current …

Sand transport in Chioggia Inlet, Venice Lagoon and resulting morphodynamic evolution
The magnitudes and pathways of sand transport in Chioggia Inlet, southern Venice Lagoon, and the resulting morphological evolution have been investigated. Bathymetric analysis has established that there is a net export of sediment from the southern Lagoon Basin, and that significant morphodynamic …

Sand transport in northern Venice Lagoon through the tidal inlet of Lido
The provenance and transport 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 …

An Analysis of Shoreline Change at Little Lagoon, Alabama
In Alabama, the term "coastal shoreline" applies to the Gulf shoreline and the shorelines of estuaries, bays, and sounds connected to the Gulf of Mexico and subject to its tides. However, Alabama shoreline studies have yet to include Little Lagoon, which has been connected to the Gulf of Mexico for …

GEOLOGICAL LEGACY OF A HISTORIC WAVE-DOMINATED TIDAL INLET, CENTRAL NEW JERSEY
… its migration to the south, consistent with the longshore transport direction. My study confirms that Cranbury Inlet was at least 4-5 m deep and started filling up several years before closing in 1812, gradually shoaling more each year until it was finally closed. In the following century, there …
