There are two intertwined "sets" of effects to be modeled:

Primarily Earth + Moon, with a secondary twist of Sun, and a layered decline of precession | orbit woblle, lessor effects (the astro forces),

And then the ground effects; shaping around headlands, sloping of seafloors, funnelling through channels, etc. with a rinse and repeat cycle for sea areas that are "chained" backwards from the main flux via multiple bays and estuaries (internal bodies of water large enough to have their own tides via mood gravity while also connected with a delay to an outer ocean via a long channel, etc.

Fun stuff - I primarily worked with exploration geophysics but dabbled a little in tides and ocean levels across Australia.
