Earth dam under floods or wave loads
Earth dam under floods or wave loads
(OP)
If you have earth dam composed of low permeability soils and this dam is exposed to flood , it should shear under undrained case. However, in most practice earth dams and levees are usually analyzed considering undrained shear only when they are under rapid drawdown case. Why the undrained analysis is not considered when such dams and levees are subjected to floods ( during the flood loading).

Most dams do not have large changes in water levee that occur very quickly, however, it can happen. Levees on the other hand often have quick changes in water level.
If the undrained strength of the embankment, dam or levee, is low enough, then it will fail during a rapid increase in loading. However, most embankments have a high undrained strength relative to the water load, so they don't fail.
As has been stated, drained conditions generally control for most embankments.

And finally, is this a real dam being analyzed, or a hypothetical case?
