DFLOWZ is a free
application that provides a preliminary evaluation of
the area potentially inundated by a debris flow.
The method is based on the
empirical-statistical model originally proposed by
Iverson et al. (1998) to predict the runout length and
the areas affected by lahars (LAHARZ model). DFLOWZ
extends the Iverson’s model to debris flow phenomena,
taking into account of the unconfined flow that occurs
on a depositional fan.
DFLOWZ is intended for
students and practitioners who need a simple method for
debris flow susceptibility mapping. The method can be an
alternative to more comprehensive numerical models when
calibration data are not available, or when a
preliminary hazard analysis is required.
