Morphodynamic variability of high-energy macrotidal beaches, Cornwall, UK

The morphodynamic responses of artificial embayed beaches to storm events

The morphological changes caused by storm events in two Barcelona beaches were recorded using video monitoring techniques during the period 2001–2006. Changes in shoreline position and configuration and submerged bar position and shape were analyzed during the 25 major storm events that occurred during the study period. Beach responses to storms were grouped into three categories: shoreline adv...

Understanding and predicting the temporal variability of sediment grain size characteristics on high-energy beaches

Despite representing a key parameter when modelling morphology or sediment transport, surface sediments are often assumed homogenous, with grain size temporally constant. This contribution uses a 6-year data set of monthly sediment samples to quantify the observed variability in intertidal beach sands at four energetic, macrotidal locations (North Cornwall, UK). Changes in grain size and sortin...

Analysis of multi-scale morphodynamic behavior of a high energy beach facing the Sea of Japan

Monthly cross shore beach profiles measured at the Ogata Wave Observation pier located in Joetsu-Ogata Coast, Niigata Prefecture, Japan, was analyzed to investigate multi-scale morphodynamic beach behavior. The Ogata beach, facing the Sea of Japan, is subjected to high energy wave conditions that has a strong winter/summer seasonal signature. The measured beach profiles at the beach show very s...

High-resolution simulations of a macrotidal estuary using SUNTANS

The parallel, finite-volume, unstructured-grid SUNTANS model has been employed to study the interaction of the tides with complex bathymetry in the macrotidal Snohomish River estuary. The unstructured grid resolves the large-scale, O(10 km) tidal dynamics of the estuary while employing 8 m grid-resolution at a specific region of interest in the vicinity of a confluence of two channels and exten...
