MEDIA | CONVERSATIONS IN MOTION: POOL SLOSHING

Swimming pools located near the top of tall buildings have become a common amenity in residential towers around the world. Careful consideration must be made in the selection of the pool dimensions (length, width, and water depth), otherwise the pool may inadvertently become tuned to the motion of the structure. When the pool becomes tuned with the structure, significant wave sloshing may occur on a regular basis during windy days. Pools have a minimal capability to dissipate sloshing energy, and as a result the sloshing response can increase to significant levels over relatively short periods of time. In extreme cases, the water in the pool will overflow on either side and spill into the surrounding areas. If the water is not properly contained, this can lead to damage to the pool area and the potential for water leaking to the lower levels of the building.
