What do you call it when the water of ocean rises, and then goes down? [talking about tide]?

Question

I'm talking about tide of the ocean. The dictionary says that tide is the periodic variation [up and down], but I want to know if there are two separate words for the movement of water in each direction?

Thanks

Answer 1

Bathymetry

Answer 2

ebb is outgoing tide

flood is incoming tide

Answer 3

flood tide: tide going in

ebb tide: tide going out.

A marine transgression is a longterm flooding of low lying areas due to rising sea levels. This isn't tidal but is instead controlled by ice, ocean basin shape, plate tectonics etc.
