Abstract: An orientation of wave generating devices is proposed that facilitates the creation of plunging breakers in a body of water. Water waves transform into plunging breakers under specific characteristics of water wave mechanics. Shoaling and refraction are specific processes of water wave mechanics that cause this transformation.

This orientation of wave generating devices therefore facilitates the creation of plunging breakers in a body of water. The plunging breaker can then be simulated in a manner favorable for surfing.

Abstract: In order to generate waves in a volume of water (12) of an aquarium, it is proposed that a storage container (22) which extends beyond the surface of the volume of water (12) should be provided in the aquarium (10).

Abstract: A fluid containment basin having ridges located in the bottom of the basin and furrows adjacent to the ridges to facilitate maintenance of the basin using the naturally occurring forces of gravity, wave action and fluid currents. The ridges can be formed from material taken from the furrows into shapes that facilitate wave action against the sides of the ridges. While the fluid level is above the ridges, sediment settles on the ridges and furrows, reducing the permeability of the ridges and furrows and, therefore, the drainage from the basin. Wave action against the sides of the ridges as the fluid level is lowered washes the sediments off the ridges into the furrows, thereby restoring the permeability of the ridges. The wave action can be wind generated or induced by a wave mechanism. The furrows can be allowed to become impermeable or be lined to prevent contaminates from migrating.
