20140257776 | AUTOMATED METHOD AND SYSTEM FOR PREDICTING HIGH RESOLUTION TIDAL HEIGHTS AND CURRENTS IN COASTAL ZONES - System and method for automatically and regularly predicting water level and currents in coastal areas, without operator intervention. The system and method can enable automated operational forecasts at regular time intervals without operator intervention by using a grid and a computer forecast model that allows accurate prediction of tidal heights and currents in complex shoreline and bathymetry regions, single or parallel processing capability, optimal available processor assignment based on the size of computing domain, standard and other tidal database forcing in the open boundary, missing data gap-filling, and wind, bathymetry, and model-derived boundary condition model integration. | 09-11-2014 |
