Spatial variability in washover deposits : Hurricane Ike and the Texas coast
Washover sand deposits are common depositional features caused by large storms that affect coastal areas. Hurricane Ike was a powerful storm that hit the gulf coast in September of 2008, the track of the eye crossing Bolivar Peninsula in Texas. The attempt was made to exhaustively identify and map …

Sedimentological Characteristics and 3-D Internal Architecture of Washover Deposits from Hurricanes Frances, Ivan, and Jeanne
… and internal sedimentary architecture of fresh washover deposits resulting from inundation to collision regime overwash events. Sedimentological characteristics and 3-D internal architecture of the washover deposits were studied through coring, trenching, sediment analysis, ground penetrating …

Quantifying overwash flux in barrier systems : an example from Martha’s Vineyard, Massachusetts, USA
… overtopping during storms, causing deposition of washover fans on their landward sides. This study examines three washover fans on the south shore of Martha’s Vineyard using a suite of data including vibracores, ground penetrating radar, high resolution dGPS, and LiDAR data. From these data, the …

Coastal Overwash: Processes and Modelling
… events and the magnitude and shape of the washover deposited during them. Although a number of studies describing overwash and washover deposits have been published, there remains a large scope to describe overwash processes, overwash hydrodynamics and to develop models for predicting the …

Comportamento morfológico e sedimentológico do litoral de Itaipuaçú (Maricá) e Piratininga (Niterói), RJ, nas últimas três décadas
… (2) mapping the sand barrier crest and washover fans with DGPS; (3) analysis of the aero photographies and satellite images; (4) comparing new data to dataset published by several authors between the decades of 1970 and 2003. The results show that the Itaipuaçú beach presents very …

Holocene Geology and Migration of a Low-Profile Barrier Island System, Metompkin Island, Virginia
… additions along the southern island segment. Washover was the primary sand source to landward profile segments during recession, supporting the concept of barrier rollover.</p> <p>Sediment deposits of the barrier island system include thick sequences of fine-grained, bioturbated backbarrier …

Pedogenesis, Inventory, and Utilization of Subaqueous Soils in Chincoteague Bay, Maryland
… paleo-flood tidal delta, shoal, storm-surge washover fan flat, storm-surge washover fan slope, and submerged headland. Previously established soil-landscape models were evaluated and utilized to create a soils map of the area. Soil profile descriptions were collected at 163 locations …

Coastal evolution on Earth and Titan
… propose a novel dimensionless metric called the Washover Ratio which compares cross-shore (overwash) and alongshore transport. Using this ratio, I find that decreases in overwash flux within the narrow middle section—possibly representing the effects of development—lead to a diminished response …

Alongshore coupling of eco-geomorphological variables in a beach-dune system
… becoming increasingly vulnerable to erosion and washover due to sea-level rise and changes in storm activity with changing climate. The impact, however, is not consistent within and across coastal barriers and there is a need to examine the alongshore variability of beach-dune systems to …

Response of the Texas coast to global change: Geologic versus historic timescales
… the upper Texas coast. It appears that hurricane washover and offshore sand deposits are minimal sand sinks, while flood-tidal deltas are areas of significant sand sequestration. Additionally, it appears that damming of rivers has had only a minimal effect on sedimentation along the upper Texas …
