The best hope would be that the mountains and ground whittle it down and that it drains quickly. May explain why rodents survived, in that dry to moderately dry ground doesn't soak up water quickly, so if it drained away before the burrows were soaked/drowned, there is a chance at survival.

Likely such a wave would scour the coastline many, many miles inland and the land would essentially have to be re-settled all over again by all of the life forms that thrived there before. There is very little chance that a burrow would not be flooded, but many rodents are good swimmers and there will be lots of stuff floating about.

There was a lot more to worry about than the wave. Anything within about 1500 km of the impact site was instantly vaporised. Then afterwards the whole atmosphere was oven-hot for several minutes. Then there was very little sunlight for decades. https://www.youtube.com/watch?v=dFCbJmgeHmA https://www.youtube.com/watch?v=dFCbJmgeHmA

  Is it the consensus that the entire planet's atmosphere was oven hot from re-entering ejecta, or is that just one particular model? I've heard various claims about the dinosaur extinction event, from the nuclear winter type scenario to all the non-avian ones dying with in an hour to a day after the impact. I've also heard different nuclear holocaust scenarios from the nuclear winter lasting as long as 10-15 years, to there being no nuclear winter, all depending on whether the burning material reaches the stratosphere in large amounts. Safe to say we don't have real world examples to test at planetary scale, so I'm a little skeptical as to how accurate any of these models are. We just know the result was a planetary-scale extinction event for at least 60% of life, although there is also the possibility of multiple impacts, and previous volcanic activity aiding the extinction.
