Seasonal to Decadal Variability of Longshore Sand Transport at the Northwest Coast of Portugal
Longshore sediment transport (LST) is a major driver of coastal evolution. However, despite the recognition that it presents an unsteady behavior at the seasonal scale, the variability at longer term scales (interannual and decadal) is still far from being properly acknowledged. The present work contributes to the understanding of the seasonal to decadal variability of the LST, benefiting from recent developments in wave hindcast modeling. This work was developed for the northwest coast of Portugal, which is fully exposed to the highly energetic wave regime generated in the Northeast Atlantic Ocean that induces unusually large LST rates. Hindcast offshore waves, between 1953 and 2010, were used as offshore forcing to deduce LST estimates. The mean annual LST, between 1953 and 2010, shows an irregular and noncyclic pattern. Computed mean annual LST, for this coastal stretch, is around 1 million cubic meters directed to the south, with yearly averages ranging from 108,000 to 2.24 million m3 year−1 a...

Effect of Inlet Morphology and Wave Action on Pollutant Pathways and Sediment Dynamics in a Coastal Stream
Hydrodynamics and water renewal of intermittent coastal streams are highly variable, at various time scales, due to the very active morphodynamic behavior of their inlets. Due to this strong dynamics, the pathways of water-borne materials — and the consequences of contaminated discharges — can depend strongly on the morphology and environmental conditions. Predicting the fate of contaminants in these systems requires coupled numerical models accounting for the major physical and water quality processes. We aim at improving the understanding of the impact of inlet morphology and wave action on the pollutant and sediment pathways of these small coastal systems, based on a suite of calibrated and validated coupled models. Two analyses, based on particle simulations, are presented to assess sediment dynamics and pollutant pathways for several conditions. Results show that waves have a major effect on the fate of water-borne materials in the estuary. Wave-induced currents sweep away materials coming out of the estuary, while wave-induced setup has a profound effect on tidal propagation, water levels and velocities in the estuary, promoting the upstream transport of pollutants.
