Is it always better to use friction values in inundation modeling, even when we have high-resolution DEM, where rough surface changes are detailed?

I am aware of computational costs while working with high resolution data, so this question is more of hypotetical nature and is related to the relevance of friction parameter in inundation...

I am going to repeat myself, but if you have access through your science library or lab, I would encourage you to search within SciFinder Scholar and/or ISI Web of Knowledge (really science citation index). You can find papers through those if these data are known. A good science librarian can aid in the search, because they have training to aid in drilling down into mountains of data.
