Dear Marcio,

I would need more data in order to help you on that task but in general terms it depends of what kind of island are you talking, a coastal or oceanic island?
In the first case, you won´t find much problems in term of modelling, you can considered as land and it would be enough.
In the latter, because normally they present a steep bathymetry my recommendation would be to use cartesian coordinates instead of sigma ones.

This rule normally can be applied to areas with steep gradients of bathymetry.

Hope this helped, best regards,
