Free, fast, powerful tool for constructing computational grids for ROMS (Regional Ocean Modelling System). GridBuilder replaces the venerable Seagrid software by Charles R. Denham.
This is a Matlab toolbox that should install and work with versions of Matlab 2014b and above. It has been developed and tested on Windows 7 but should work on any platform that can run a compatible version of Matlab. Installing the toolbox will install all code and data files and help documentation required to run GridBuilder. To install the toolbox double click on the GridBuilder.mltbx file from within Matlab.
Let’s say we want to compare the vertical level of an island benchmark with an onshore benchmark which has been levelled into a national datum. There are a number of ways this can be done. Here I discuss three of them.
This Matlab function prepares a ROMS forcing file directly from the Oregon State TPXO global tidal model. ROMS is a hydrodynamic model primarily designed for coastal shelves, estuaries, and regional seas. This new version of TPXO2ROMS (TPXO2ROMSv5pt1) reads from the new TPXO 9 atlas. TPXO 9 has various improvements, including the tidal harmonic 2N2 and the meteorological harmonic S1 (which I omit due to its unsteady barometric origin). You will need permission to download the TPXO9 netcdf files this software reads from (see volkov.oce.orst.edu/tides/otps.html). In the unlikely event (ahem) anyone finds any errors please inform me so I can update the software accordingly.
I wrote this handbook in 2004 under contract to the National Tidal Centre (Bureau of Meteorology). It is now out of date, with the most important contents merged into Modern Theory and Practice of Tide Analysis and Tidal Power.
