Size-selective sediment transport and cross-shore profile evolution in the nearshore zone
… often leads to threatening consequences such as beach erosion and shoreline retreat that concern the coastal community. A new, comprehensive cross-shore morphodynamic model was developed that can be used to describe and predict these phenomena. The study included both physical and numerical …

DYNAMIC EQUILIBRIUM BEACH PROFILES: FORCES OF OFFSHORE SEDIMENT TRANSPORT IN MARYLAND’S CHESAPEAKE BAY
… empirical and theoretical models of offshore profiles. The data collected at each site included a series of three-dimensional bathymetric profiles from offshore transects run at each site, as well as a series of sediment core data that were acquired along each transect. Relationships between …

Coastal Overwash: Processes and Modelling
… flow of water and sediment over the crest of a beach system when the runup level of waves or the water level, often enhanced by storm surge, exceeds the local beach or dune crest height. The impacts of overwash on coastal barriers or low lying mainland coasts are striking. Overwash may cause …

Beach development and movement as a function of water waves
… relationships for momentum flux. The near shore beach environment is discussed in detail with regard to the wave forces acting on it, beach forms, and three-dimensional circulation patterns. Part Two deals with experiments conducted in the hydraulics laboratory, Department of Civil Engineering, …

Factors controlling the mobility of shingle beaches, with particular reference to the north Kent coast
Despite their scarcity on a global scale, shingle beaches are a common feature of the coastline of the UK, in particular southern England. Shingle beaches have the ability to dissipate large amounts of wave energy over short distances. As a result of this ability, shingle beaches have become a …

SPH modeling of the vertical flow structure and turbulence in the swash
… with a flat sea surface and the measured beach profile and is forced at the offshore boundary with waves observed in 5 m water depth. The model is used to simulate the cross-shore and vertical structure of wave orbital motions, turbulence, and time-mean flows across the surf zone to the …

Caratterizzazione morfodinamica della spiaggia del Poetto
… modify the geomorphological aspect of beaches, including along the coastal zone where beach front intense human activities cause coastal damage, as well as civil protection issues. This factor is particularly relevant along urban beaches, where managing coastal erosion and maintaining …

The morphodynamics of a sand and gravel barrier, Southern Hawke Bay, North Island, New Zealand
Little is known about mixed sand and gravel beaches over an extended time period (seasons) or for specific wave energy events. This thesis addresses this problem by analysis of the gravel textures (sizes and forms) and the cross-shore transverse profiles for the southern Hawke Bay barrier, which …
