• Resumen

  • We developed a particle tracking model to estimate sediment transport in coastal areas where there are protection works, this will make the calculation of the hydrodynamics of the study area by identifying the three-dimensional velocity field in conjunction with the spread wave and the associated pheno- mena (di.raction and reflection) on the free surface allows particle transport independently in any direction in space caused by the velocity field and the turbulent dispersion (type random Brownian motion). Dispersal mechanisms and re-suspension of particles used were represented by stochastic models, which describe the movement by means of a probability function.

    Model validation was carried out with two cases with known numerical solution using a discrete-continuous transformation method PIC (Particle in Cell), obtaining lower percentage average relative errors to 4.8 % in both cases. The results of simulating the transport of 350,000 particles under di.erent scenarios can determine areas susceptible to erosion and clogging which houses a pipeline (pipeline or pipeline) in a coastal.
