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 کاملEnvironmental Impact of Beach Nourishment: A Case Study of the Rio San Pedro Beach (SW Spain)
The beaches on the left bank of Rio San Pedro (SW Spain) are in a regressive state because of the human activities of recent decades. With the objective of minimizing the effects of the erosion, the Spanish Coastal Department (Ministry of the Environment) decided that the most suitable solution was to provide sand nourishment. Previously, an environmental impact study (EIS) was carried out on t...
متن کاملMacrofaunal sediment selectivity considerations for beach nourishment programmes.
Nowadays, beach nourishment is widely considered as a better alternative compared to the construction of hard structures to protect a sandy coast against detrimental erosive effects, both from an ecological and an engineering perspective. The rare studies conducted on the ecological impact of beach nourishment are short-term, post hoc monitoring investigations of the benthic macrofauna. Little ...
متن کاملSpectral responses of gravel beaches to tidal signals
Tides have been recognized as a major driving forcing affecting coastal aquifer system, and deterministic modeling has been very effective in elucidating mechanisms caused by tides. However, such modeling does not lend itself to capture embedded information in the signal, and rather focuses on the primary processes. Here, using yearlong data sets measured at beaches in Alaska Prince William Sou...
