[MITgcm-support] Problem with Bathymetry

[Klymak Jody]

Hello Abbas:

Three suggestions - 1) rotate your lake to run "N-S" or "E-W" and then  
use far more grid cells in the long direction.

2) change dx and dy in the vicinity of the canyon. delx and dely do  
not need to be constants.

3) simply teak the topography by hand to include the canyon if it is  
important to your dynamics.

Cheers,  Jody
