Optimization of Bathymetry Database for Coastal Areas

Abstract

Problem statement: A database containing gridded bathymetries with different coverages and resolutions has been established. Approach: The interpolation techniques of the gridded bathymetries have been developed to define the spherical, rectangular and curvilinear coordinate grid systems. Results: Subsequently, merging of the bathymetry results has also been developed to define the optimal bathymetry. Furthermore, the bathymetries were established in order to apply for the Gulf of Thailand (GoT) and also for the storm wave and surge models of the Coasts of Thailand (CoT). Conclusion: The bathymetry covering the coastal waters was produced to extend the applicability of the operational 2D and 3D ocean models. In addition, the data sets used in this study were integrated and collected in order to be the database and post processing tools to convert the output to the specific formats required for various operational models at the CoT.
