Dambreak analysis is very complex, requiring a lot of in-channel
cross-section or bathymetric data and over-bank DEM data, as well as the
use of an unsteady hydraulic flow model such as the U.S. Army Corps of
Engineers, HEC-RAS model, which has this capability.

However, there are simplified techniques that can approximate detailed
analyses, such as:
