Pintohoo,
try www.nearmap.com
Great up to date mapping website. There is a button named terrain. Click on it.
Be a bit tongue in cheek, but you should know your product.
With the raw numerical data behind the terrain maps, a database could map flood flows at different extremes.
Nearmap capture Terrain data automatically on each flyover. I presume they derive the terrain data from the image data using photogrammetry:

Do others know?
