During a cycle of sea-level variation, coastal environments develop in different position the continental shelf following seaward and landward shift coastline. They vary widely character, reflecting wide range process-regimes that are brought about during stages variations. Within this scenario, morphology shelves, mainly resulting from combined effect tectonic activity eustatism, plays an impo...

In 332 B.C., Alexander the Great constructed an approximately 1,000-m-long causeway to seize the offshore island of Tyre. The logistics behind this engineering feat have long troubled archaeologists. Using the Holocene sedimentary record, we demonstrate that Alexander's engineers cleverly exploited a shallow proto-tombolo, or sublittoral sand spit, to breach the offshore city's defensive impreg...

The Lower Triassic Sinbad Formation (Thaynes Group) in the San Rafael Swell of east-central Utah (11-18 m thick) represents the maximum flooding zone and at least part of the highstand systems tract of a 185+ m thick depositional sequence. The Sinbad Formation conformably overlies siliciclastic tidal flat, fluvial channel and carbonate peritidal deposits of the Black Dragon Formation, a transgr...

The evolution of a barrier island and its stratigraphic architecture is investigated with the numerical model BIT (barrier island translation). The model simulates, with simplified equations, the effects of various processes (wind waves, storm surges, sea-level oscillations) on sediment location and characteristics. The presented formulation is able to reproduce both the cross-shore profile and...

A Permian bentonite deposit at Melo, Uruguay is composed of a calcite-cemented sandstone containing clay pseudomorphs of glass shards (0-0.50 m) overlying a pink massive clay deposit (0.50-2.10 m). The massive bed is composed of two layers containing quartz and smectite or pure smectite respectively. The smectite is remarkably homogeneous throughout the profile: it is a complex mixed layer comp...

This paper presents the results of a study on fluctuations in water level Curonian Lagoon (in Baltic Sea). To date, genesis this inland bay as part complex postglacial development southeastern is poorly understood. The data from lithological, geochronological, and phytolith analyses, well assessments plant animal macroremains lagoonal sediments, provide reconstruction local coastal biocenoses d...

Increasing societal pressures (e.g., population growth and urbanization) are driving land use change practices in coastal areas that could potentially alter the hydrodynamics sediment transport patterns near inlets ways might exacerbate existing shoaling conditions. To investigate potential impact of development, a numerical model is used to predict long-term evolution an idealized lagoonal-typ...
