Abstract/Additional Information

A one-dimensional unsteady mud/debris flow modeling technique is beingincorporated into the National Weather Service (NWS) FLDWAV dynamic flood routing model enhancing its capability to model unsteady flows of non-Newtonian fluids. This technique involves determining the friction slope of mud/debris flows based on a semi-empirical rheological power-law equation and a wave-front tracking technique. Three similar techniques are compared for model performance on three real-case mud/debris flow simulations and with some model sensitivity studies.
