How to calculate vertical distance downhill from ridges

Discussion created by frank.hanssen@nina.no on Mar 6, 2012
I have computed a raster with ridges (see figure: elevation in colours from green (low) to red(high)).

I need to find all part of the terrain that is 30 meter lower than each ridge.

Any ideas on how I can solve this?
