Common uses of DEMs include:
* Extracting terrain parameters for [[geomorphology]]
* Modeling [[water flow]] for [[hydrology]] or mass movement (for example [[avalanche]]s and [[landslide]]s)
* Modeling soils wetness with Cartographic Depth to Water Indexes (DTW-index)<ref name="Campbell">{{Cite journal|last1=Campbell|first1=D. M. H.|last2=White|first2=B.|last3=Arp|first3=P.
