The underlying model used to model falling water was a particle system. The key to the desired behaviour was to determine a visually correct set of interactions between particles. This was done with careful comparison and analysis with real world water structures.
Once the base model was created, it was refined to include basic physical properties such as gravity and air resistance (dependent on water volume size). Next realistic collisions with several geometric objects were modelled such as spheres, planes, polygons, triangles and cubes.
The affect of wind on a falling water volume was modelled next, as well as mist (including creation, movement and causes of destruction).
Finally limited experimentation attempted to replicate the noise produced from a volume of falling water striking an object.
