Short summary
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. Our paper reviews key modelling approaches applied in estuaries analyzing their setups and parameterizations. We provide recommendations and future directions to improve the accuracy and modelling strategies for estuarine microplastic research.

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.

Short summary
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.
