Implementation of a 3-Dimensional Hydrodynamic Model to a Fish Aquaculture Area in Sines, Portugal - A Down-Scaling Approach

摘要

Coastal zones have always been preferential areas for human settlement, mostly due to their natural resources. However, human occupation poses complex problems and requires proper management tools. Numerical models rank among those tools and offer a way to evaluate and anticipate the impact of human pressures on the environment. This work describes the implementation of a hydrodynamic 3-dimensional computational model for the coastal zone in Sines, Portugal. This implementation is done with the MOHID model which uses a finite volume approach and an Arakawa-C staggered grid for spatial equation discretization and a semi-implicit ADI algorithm for time discretization. Sines coastal area is under significant pressure from human activities, and the model implementation targets the location of a fish aquaculture. Validation of the model was done comparing model results with in situ data observations. The comparison shows relatively small differences between model and observations, indicating a good simulation of the hydrodynamics of this system.
