[Interstellar] How tall is the wave on the water planet that's near the black hole? Could it be concieved that there IS land somewhere on that planet, even with these waves?

I was always puzzled how they don't notice the planet was all water. Same goes for the planet Damon landed on. They traveled all that way, and never once thought to reconnoitre thier destination.

I always wondered if the combination of gravity and water managed to erode whatever landmass that used to poke above the water.
