TL;DR: In this article, a study of sediment dynamic processes on the lower shoreface in the presence of small-scale bedforms is presented, showing that ripple migration and bedload transport are only a small contribution to onshore sediment transport under low to moderate energy conditions.

TL;DR: In this article, a three-dimensional sediment transport model implemented within the Proudman Oceanographic Laboratory Coastal Ocean System (POLCOMS) is presented, where suspended sediment concentration is calculated following advection-diffusion schemes similar to those used for other scalar quantities.

TL;DR: In this article , the role of the estuary length in salt intrusion was investigated using a process-based, idealized, semi-analytical three-dimensional model, and it was shown that substantial decreases in L relative to Lw/4 can change the dominant landward salt importer from tidal pumping to horizontal diffusion.

TL;DR: In this paper , wavelet analysis is applied to quantify the variability of salt intrusion from hourly to seasonal timescales and unravel the temporal variability of its response across scales, showing that tides control the response time more strongly than river discharge, even though river discharge determines the magnitude of the salt intrusion.

TL;DR: In this paper, a decade of Conductivity Temperature Depth (CTD) sensor observations were collected during cruises across a nearshore grid of monitoring stations to validate numerical simulations using the 1-way nested Proudman Oceanographic Laboratory Coastal Ocean Modelling System (POLCOMS) at 1.8km and 180m horizontal resolution.
