Comportamento morfológico e sedimentológico do litoral de Itaipuaçú (Maricá) e Piratininga (Niterói), RJ, nas últimas três décadas
… greater vulnerability of this area to southwest storm waves. The beach sediments are very coarse sand and pebbles in the west sector and bettersorted coarse sand toward the east. The mapping of the sand barrier crest and washover fans present to the west of the sandy barrier in Itaipuaçú revealed …

Field observations and numerical model simulations of a migrating inlet system
Waves, currents, and bathymetric change observed along 11 km of the southern shoreline of Martha’s Vineyard include storm events, strong tidal flows (> 2 m/s), and an inlet migrating 2.5 km in ~7 years. A field-verified Delft3D numerical model developed for this system is used to examine the …

Análise das pegadas fósseis de tetrápodes do Permiano Superior da Bacia do Paraná
… They were originated under the action of the storm waves in a tidal flat depositional system and it would have been produced during the swimming next to the bottom. The footprints from Corumbataí Formation were identified as Tridactylichnium ichnosp. And atributted to the archosauromorphs, …

Hábitos de vida dos trilobitas das formações Maecuru e Ererê (Devoniano), Bacia do Amazonas
… were probably parautochthonous and deposited by storm waves; and the blioclasts from the Maecuru River, OAD 4 and OAD 4A points, which could indicate different depositional events, time averaging and allochthonous and/or parautochthonous assemblages. The Ererê Formation presents allochthonous …

Bottom boundary layer physics and sediment transport along a transgressive sand body, Ship Shoal, south-central Louisiana: implications for fluvial sediments and winter storms
… in concert with fluvial sediments and winter storms, influenced in unique ecosystems, and likely in future potential sand mining. This dissertation addresses such the morphodynamics and sedimentary processes and their implications for the mining from the shoal using field measurements and …

Wave Characteristics and Transformations on Sub-Horizontal (Type B) Shore Platforms on the East Coast of the North Island, New Zealand
… The Auckland experiments were conducted under storm conditions to explore the interaction of storm waves with the platform surface. Results showed that breaking was forced on the platform edge when the relative water depth (depth/significant wave height) at the edge was less than 2.5; whereas …

Relationship between coastal vegetation biomass with elevation and salinity gradients
Surges and waves generated by hurricanes and other severe storms can cause devastating damage to property and loss of life in coastal areas. Vegetation in wetlands and coastal fringes can reduce storm surges and waves while complementing traditional coastal defense approaches such as permanent …

Coastal Storm Activity along the Eastern North Island of New Zealand - East Cape to Wellington
Coastal storm activity for the eastern North Island, between East Cape and Wellington, has been quantified from a meteorological perspective through the use of cyclone tracks and extreme winds and from an oceanographic perspective by using hindcast wave information. It has culminated in the …

A quantitative analysis of shoreline erosion processes, Lake Sakakawea, North Dakota
… pool level is reached sometime in mid-summer. Storm waves easily erode the loose calluvium along the base of the banks. If all the colluvium is eroded, the waves can remove the primary sediment or bedrock, effectively under cutting the banks. At the top of such banks, extensional joints are …

Petrogenesis of Pliocene limestones in southern Hawke’s Bay, New Zealand: a contribution to unravelling the sequence stratigraphy and diagenetic pathways of cool-water shelf carbonate facies
… of environments ranging from below storm-wave base, in outer shelf-type locations, to predominantly shallow-water shoreface-type conditions under the influence of strong tidal current flows and storm waves. A new petrographic approach for studying cool-water carbonate diagenesis has …

Plant-habitat interactions in brackish marshes
… furthermore reduce the destructive effects of storm surges and storm waves and thus contribute to ecosystem-based shore protection. However, in many estuaries, extensive embankments, artificial bank protection, river dredging and agriculture threaten tidal marshes. Global warming might entail …
