The word for today is…

undulate (adjective, verb):

*adjective* (or undulated)  
: having a wavy surface, edge, or markings

*verb*  
1: to form or move in waves  
2: to rise and fall in volume, pitch, or cadence  
3: to present a wavy appearance

Source : [Merriam-Webster](https://www.merriam-webster.com/dictionary/undulate?ref=goodoil.news)

Etymology :Undulate and inundate (“to cover something with a flood of water”) are word cousins that flow from unda, the Latin word for “wave.” No surprise there. But would you have guessed that abound, surround, and redound are also unda offspring? While their modern definitions have nothing to do with waves or water, at some point in their early histories, they all meant “to overflow,” and caught a wave from there.
