I'm trying to analyse an area/DEM with these two criteria:
-Even sloping terrain steeper than 1:20 and total slope height > 5 m.
Finding areas with slope of 1:20 (5%) could be done with the slope function. But I can't figure out an easy way to filter these areas to only include areas with slope height over 5 meter. I.e. the total vertical height form start of slope to top should be at least 5 meters.
Anyone have any ideas or thoughts on this problem?
Background: The criteria are to identity possible land slide areas (quick clay), so it's already clipped to only include areas of old marine sediments. https://www.ngu.no/en/topic/quick-clay-and-quick-clay-landslides
