Bed Change Methods Should Apply to Morphologically Similar Reaches, not to Individual Cross Sections
Just because HEC-RAS allows users to define different bed change methods for each cross section, does not mean they should. This method should not change from cross section-to-cross section. If you do choose to override the default method, it should be for a particular reason over a coherent morphological setting, usually comprising a set of consecutive cross sections.

Examples of appropriate application of these local bed change methods would be:
- Choosing the Reservoir method for channel deposition along the topset slope of a reservoir delta while the Veneer method is the default elsewhere.
- Using the Simplified CEM method to compute erosion for a dam removal through the reservoir deposits, but default to the Veneer method for erosion downstream of the dam.
