Fjord Tidal Test Case
Warning This WikiROMS article is currently under HEAVY construction. This message will be erased when active construction is finished (in 1 or 2 days).
April 14, 2008

This tutorial will go over some of the basic steps to set up a ROMS realistic application (yet, this is a very simple one). This tutorial is also a demonstration of how to use EASYGRID, a "quick-and-dirty" matlab script to make ROMS grids and initialization files.


Warning PREREQUISITES: This tutorial assumes that you have (1) downloaded ROMS, (2) installed it in your computer (or cluster), (3) tested it by compiling and running one of the included test cases, and (4) installed MEXNC, SNCTOOLS and the ROMS Matlab tool-kit. If you haven't done all the above, check the "Getting Started" and "Tutorials" WikiROMS sections.



Geographical Setting: This application is for Ship Harbour, an estuarine fjord in Nova Scotia, Canada. Click here to see the location in Google. Tides are semidiurnal and tidal range is 1.4 m on average and 2 m on spring tides. For now I will only include tidal forcing, however, there is a river at the uppermost end of the estuary, which discharges freshwater at an annual average rate of 18 m3 s-1. I plan to write another tutorial on how to add a river, but for now is only tides. Ship Harbour has a shallow sill of approximately 7 m depth. Average depth of the inner basin is 15 m with a maximum of 25 m.



Grid Generation

The first step to set up a realistic application is to set up a realistic grid. There are several software packages to generate ROMS grids. Here I will use EASYGRID.

Get bathymetry and coastline

Initialization

Create header (.h) file

Create a copy of the basin.h test-case header file, and rename the copy fjord.h

fjord.h file: Start with basin.h ...then Erase red and Add green (black remains the same).
