Modelling Infiltration on Gravel Beaches with an Xbeach Variant
Coarse-grained beaches are particularly prevalent in the UK, composed of accumulations of either gravel, or mixed sand and gravel sediments. Understanding and predicting their morphological behaviour in response to short-term and long-term forcing has been the subject of recent research. Despite the focus on sandy beaches, it is important to understand that the balance of processes that govern ...
متن کاملObservations of gravel beach dynamics during high energy wave conditions using a laser scanner
A 2D laser-scanner was deployed at the high tide runup limit of a pure gravel beach (Loe Bar, Cornwall, England) to measure high-frequency (2.5 Hz) swash hydrodynamics and topographic changes during an energetic wave event. Measurements performed with the laser-scanner were corrected to compensate for levelling and orientation errors, and a variance threshold was applied to separate the beach t...
متن کاملNonlinearity and complexity in gravel bed dynamics
The dynamics of river bed evolution are known to be notoriously complex affected by near-bed turbulence, the collective motion of clusters of particles of different sizes, and the formation of bedforms and other large-scale features. In this paper, we present the results of a study aiming to quantify the inherent nonlinearity and complexity in gravel bed dynamics. The data analyzed are bed elev...
متن کاملHydrodynamics in a gravel beach and its impact on the Exxon Valdez oil
[1] This paper investigated the interaction of groundwater and seawater in a tidally influenced gravel beach. Field observations of water table, pore water salinity were performed. The two‐dimensional finite element model MARUN was used to simulate observed water table and salinity. Based on field observations and model calibrations, a two‐layered beach structure was identified which is charact...
متن کاملModeling Ocean Dynamics at Waikiki Beach
Acknowledgements I would like to thank Baylor Fox-Kemper for not only advising me on my thesis, but also providing valuable information about pursuing a career in physical oceanography. Also, I would like to thank Mark Merrifield, who got me involved in this project and provided all the data collected from Waikiki. Finally, I am greatly appreciative of Brad Marston, for providing me with the op...
