Validation of the 3D-MOHID Hydrodynamic Model for the Tagus Coastal Area

摘要: The hydrodynamics of the TagusROFI (Regions Freshwater Influence) is affected by coastal upwelling, estuarine tidal flow, thermohaline circulation that modulated Tagus freshwater discharge, and its complex bathymetry. use numerical models best way to explain processes characterize this region. These are also crucial answer important scientific management questions. Nevertheless, robustness products derived from depend on their accuracy therefore must be validated determine uncertainty associated. Time space variability driving forces bathymetry enhance flow complexity increasing validation difficulties, requiring continuous high-resolution data describe horizontal vertical variabilities. In present work, increase precision simulations, sub-systems area estuary were integrated into a single domain, which considers higher resolution grids in both directions. three-dimensiosal (3D)-MOHID Water model was for comparing statistically modelling results with situ satellite L4 data. Validation conductivity, temperature, depth probe (CTD), an acoustic doppler current profiler (ADCP) performed first time. against gauges showed able simulate propagation inside accuracy. A very good agreement between CTD surface sea water temperature (SST) salinity simulations observed. direction velocity ADCP indicated high these variables. Comparisons SST produces realistic SSTs upwelling events. Overall MOHID setup parametrisations well implemented domain. even more when 3D used due once it discretization allowing better representation heat fluxes column. Moreover, achieved indicates 3D-MOHID robust enough run operational mode, including forecast ability, fundamental as tool.
