Morphodynamic variability of high-energy macrotidal beaches, Cornwall, UK [PDF]
Marine Geology, 2014 Abstract Spatial data collected over three years are presented to assess the extent of morphological variability under seasonal and storm waves on two high-energy macrotidal beaches on the north Cornish coast. Of particular interest was the degree to which the beaches displayed bar/rip morphology and a novel approach to quantify the three ...

A hybrid beach morphology model applied to a high energy sandy beach
Ocean Dynamics, 2015In this paper, the application of a hybrid coastal morphodynamic model to forecast inter-annual beach change is discussed through the prediction of beach change in a high energy sandy beach over a period of 5 years. The modelling approach combines a ‘reduced-physics’ formulation with a data-driven approach through an inverse technique to form the ...

Aerobic respiration in a high-energy sandy beach
Marine Chemistry, 2013Abstract Wave and tide dominated beaches are composed of medium to coarse sandy sediments depleted in organic matter. In these sediments, the availability of organic matter limits benthic heterotrophic respiration processes. This study shows that oxygen consumption linked with nutrient recycling occurs in sands and that the intensity of this process ...

Behaviour of diesel fuel on a high energy beach
Marine Pollution Bulletin, 1985Abstract On 1 March 1984, a spill of diesel fuel and gasoline on the east coast of the Queen Charlotte Islands, Canada, resulted in significant contamination of the beach. Sediment and water samples analysed for oil concentration indicated that oil moved through the beach sediments in response to the tidal cycle and the subsequent changing water ...

Extreme erosion on high-energy embayed beaches: Influence of megarips and storm grouping [PDF]
Geomorphology, 2012 Megarips have long been recognised as an important, yet poorly documented, mechanism of beach erosion on high-energy embayed beaches. The persistence and cumulative effect of megarips during storm groups, are described from three embayed beaches (Arrifana, Mt.

Sampling Macroinvertebrates on High-Energy Sand Beaches
2023This report summarizes the most practical and cost-effective techniques developed from CERC-sponsored research and the literature for quantitatively sampling high-energy sand beach macroinvertebrates. The general habitat, the field crew's qualifications and duties, and the materials and equipment are described.

Sand beach energetics: An ecosystem approach towards a high energy interface
Estuarine, Coastal and Shelf Science, 1981General results of a study of energetics on open sandy beaches in South Africa are presented. These sand beaches are considered to interact with adjacent terrestrial environments via the sand dune system and with the sea via the surf zone. A food web is given for the macrofauna showing all known interactions from the supply of food material to the ...

Abstract The present work proposes a morphological evolution model for sandy cuspate beaches, which depends on two parameters, swash excursion (S) and offshore wave steepness (H0/L0). The model was derived from observations of morphology and wave climate at Renaca Beach in central Chile, comprising in-situ instrumentation, topographic surveys, wave ...
