Here are various kinds of pool kits for Japanese gardens and other scenes.

The top three sets of models feature very small waterfalls that splash into pools. The shape of each waterfall is different, as is the way in which it splashes into the pool, and the way the pool responds. All are physically accurate models of the rippling pools, the splash and the small waterfalls. Each comes with the rock j=kit shown, but you can separate the waterfall and pool from the rocks to compose your own scenes.

The sets of models on the bottm half of this page are "kits." Each has a series of components that you can use to design your own waterbody.

For example, "Bubbling Springs Kit #1" consists of 10 individually shaped bubbling surface objects. Arrange these on the top of a pool object of water plane to create any desired bubbling springs arrangement.
