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?
