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.
Highlights
A high quality fine resolution bathymetry data set has long been a priority for the operational ocean modelers
In recent years of the operational ocean prediction system, the data have faced a frequent demand of predictions of water levels (Vongvisessomjai et al, 2008), waves, surges (Wannawong et al, 2010d), tides (Wannawong et al, 2010b), currents and circulations at a very high resolution in many locations (Wannawong et al, 2010c)
The database containing data sets covering the Coasts of Thailand (CoT) from 99-111°E in longitude and from 2-14°N in latitude has been established based on existing bathymetry data at the CoT (Fig. 1)
Summary
A high quality fine resolution bathymetry data set has long been a priority for the operational ocean modelers. Ten bathymetry data sets covering different parts of the Coasts of Thailand (CoT) are available from GEODAS (Amante and Eakins, 2008; Edwards, 1989; Sloss, 2006). In recent years of the operational ocean prediction system, the data have faced a frequent demand of predictions of water levels (Vongvisessomjai et al, 2008), waves, surges (Wannawong et al, 2010d), tides (Wannawong et al, 2010b), currents and circulations at a very high resolution in many locations (Wannawong et al, 2010c) This leads to increase the high resolution of the regional and coastal models continuously.
