As a note: the tidal bulge image gives an 'equipotential'. I.e. the water level you would get in equilibrium. That part of tidal bulges is right. The part that is wrong is that the actual water level is nowhere near equilibrium, because the moon moves. In fact, the water level doesn't even approximate this equilibrium but can (and does!) behave very differently.
