This InfraWorks model was created to demonstrate flooding in the Florida Keys. I used the newer Terrain Surfaces feature to simulate the various flood stages. In this case, I used several surfaces to simulate Sea Level Rise (SLR) of 1, 2 and 3 ft stages with flooding 1 foot above SLR. This was used in conjunction with the terrain features to colorize elevation. Each flood stage "surface" was assigned a water shader material to better simulate the look of water.
