Abstract
Microplastics on coastal waters around the world are every day a bigger concern to the popu- lation. This project studies the litter concentration on Barcelona coastal waters by using repre- sentations tools in Python language, with calculation libraries written in C++. This project is based on a previous study called LOCATE, that uses the Lagrangian simulator Parcels, which is capable of predicting the movement and accumulation of floating debris in coastal waters, by combining wave and current data with simulations of the movement of rubbish particles. The objectives of the project are to understand how the LOCATE model works, implement and analyse the data of the project Surfing for Science, as well as improve the simulation by working the Stokes drift. In order to carry out the objectives, it is explained how the Lagrangian simulation (Parcels) works, and it is put to practice. The project starts by improving the numerical simulation, work- ing on the Stokes drift. Then, it implements the microplastic data collected by the project Surfing for Science, and numerically simulates it. The model predicts the movement of virtual particles and provides the potential fate and origin of the microplastics. Once the numerical simulation has been run, it is seen that beaches act as microplastics reser- voirs, since 80, 13% of microplastics have their potential origin on the different beaches, and 83, 56% have their potential fate on the same locations. In this thesis, the effect of beaching mod- els and a possible anti-diffusion component in order to better find the origin of the microplastics are discussed. To conclude, the project has a positive environmental impact, since it allows finding and erad- icating the potential microplastics’ origin, opening other lines of future investigation and im- provement to make the simulation more accurate.
