Short summary
Studies on plastic pollution have emerged as a rapidly growing field of research. Modelling microplastic transport in estuaries stems from their complex hydrodynamics and diverse particle behaviours affecting the dispersion and retention of microplastics. We review key modelling approaches applied in estuaries analysing their set-ups and parameterizations. We provide recommendations and future directions to improve the accuracy and modelling strategies for estuarine microplastic research.

This study presents a new global wave model that improves predictions of sea states in tropical areas by using a high-resolution grid and corrected wind fields. The model is validated globally with satellite data and nearshore using in situ data. The model allows for the first time direct comparisons with in situ data collected at 10–30 m water depth, which is very close to shore due to the steep slope usually surrounding volcanic islands.

This study presents a novel modeling approach for understanding microplastic transport in coastal waters. The model accurately replicates experimental data and reveals key transport mechanisms. The findings enhance our knowledge of how microplastics move in nearshore environments, aiding in coastal management and efforts to combat plastic pollution globally.

In Saint-Malo, France, an initiative to enhance marine submersion prevention began in 2018. Shom conducted an extensive sea campaign, mapping the bay's topography and exploring coastal processes. High-resolution data improve knowledge of the interactions between waves, tide and surge and determine processes responsible for submersion. Beyond science, these findings contribute crucially to a local warning system, providing a tangible solution to protect the community from coastal threats.

The French Flooding Prevention Action Program of Saint-Malo focuses on improving the knowledge of coastal flooding risks. The proposed approach is to use in-situ data collection. Bathymetric and oceanographic measurement campaigns were conducted during the winter of 2018–2019. Topo-bathymetric and oceanographic datasets have been built from these measurement campaigns. These data allow the development and validation of numerical models to improve the prediction of coastal flooding risks.

Short summary
The circulation of nearshore water is of primary importance for the health of coastal ecosystems and the coastal hazards, such as erosion. The present study focuses on the role played by bottom friction, which is particularly important in rocky or coral reef areas. Using field observations and numerical simulations, we show that the waves are able to increase the bottom friction and therefore affect the whole circulation and water level dynamics.
