A modularly assembled wave maker including: a housing internally provided with a power source with an output end extending out of the housing; and at least an impeller assembly with one end connected to the housing, including: an expanded structure for continuing the impeller assembly and an impeller body connected to an output end of the power source in a transmission way. The present invention adopting the above structure can be applied to continuously connect the impeller assembly as needed by arranging the expanded structure in the impeller assembly, so as to achieve the expansion of the present invention, which enables the present invention to be suitable for aquariums of different depths. Moreover, only a faulted part needs to be replaced when the present invention fails, so that the replacement cost is low. Therefore, the present invention has a simple structure, and is economically affordable.

A wave pool and wave generating mechanism are disclosed. The wave pool includes a bathymetry that includes a dynamically shapeable reef along a length or circumference of a channel that defines the wave pool. The wave generating mechanism includes a foil that has a shape for bi-directionality based on an adjustment of a yaw angle of the foil. The foil can be further controlled to increase or decrease certain surface areas or other angles of interacting with water in the wave pool.

A wave generating system can include a water channel for creating a flow of water to produce a standing wave. A water return passageway can circulate the water back to the inlet of the water channel. One or more pipes can extend under the water channel for circulating the water. A water storage chamber can be positioned below the water channel. Water can be stored in the space between the one or more pipes, and the storage water can be isolated from the water being circulated in the system. The system can produce a hydraulic circuit with hydraulic continuity so that water can be efficiently circulated through the water channel and water return passageway. The system can be modular.
