This shows a 3D view of a flood simulation. Different colours overlaid over the air photo represent water of different depths. White lines illustrate the water velocity vectors.
Heightfields and overlaid thematic representations of depths were generated using http://processing.org/. Each frame of the animation was rendered in Povray Open Source raytracing program.
Water elevations and velocities were obtained using the RMA2 two dimensional hydrodynamic model.
