Lagrangian particle tracking models

Definition

Lagrangian particle tracking models are computational methods used to simulate the movement and behavior of particles in a fluid environment based on Lagrangian mechanics. These models track the individual trajectories of particles as they move through the water, providing insights into processes such as dispersion, transport, and interactions with marine life, making them essential for assessing habitats and monitoring marine populations.
