Synopsis of Topic
Transient storage is defined a the total thickness over a given time period that has experienced topographic change (Hazel et al. 2006; Schmidt & Grams 2011). When you have more then three DEMs, you can perform a transient storage analysis by first deriving the minimum and maximum elevations over the entire time period for a given time series of topography. You then subtract the minimum from the maximum to get your transient storage thickness. In this lecture, we will show you how to do this analysis and discuss how you might interpret it.
Why we’re Covering it
This is a useful tool for identifying hotspots of change.
