I’m revisiting an illustration I did a couple years ago. This shows in 3D what FEMA maps and FEMA manual illustrations imply for the project. It was for presentation on Coastal Area Management Review which we often have to do on the shoreline in Connecticut. There are two types of flood planes: Velocity Zone (wave action) and a common A zone (standing water). My original illustration just showed the higher flood plane elevation for the V zone as a flat plane, but it would be a better illustration if it showed how the higher elevation actually comes from wave crests, not just a magically higher water level. After figuring out how to make a sine wave, I made simple waves in the water. The next task is to make the waves blend out into still water.
