Sensitivity Studies Using Multi-Region and Open Boundary Conditions for Terrain Bottom-Following Ocean Models
The objective of this thesis is to develop a prognostic model of the Northern Canary Current System (NCCS) based on the Princeton Ocean Model (POM) with parallel processing capabilities on a cluster of workstations and improved boundary conditions. A one-way coupling with a z-level basin scale model...

The development of this model will allow the investigation of coastal processes and the development of numerical models in order to improve the results of sigma coordinate bottom-following ocean models.
