Answer
Yes and yes.
Work Step by Step
Water waves can reflect at the edge of a swimming pool.
Refraction can be observed when water waves encounter an interface where their speed changes abruptly, for example, in a shallow pool where there is an underwater shelf/step and the water depth suddenly changes, or in a location where water currents of very different temperatures collide.
Huygen’s principle applies to water waves because they are transverse waves.
