- Abstract
- As a levee failure and the consequent flooding cause significant financial losses and sometimes human casualties, they have led to considerable concern among city officials. Therefore,
researchers have devoted considerable effort to investigating the hydraulic characteristics of sudden
transient flow in the form of propagated waves to inundation areas during a levee and/or dam failure.
A large number of studies, however, have mostly focused on simple one-dimensional cases investigated numerically and/or experimentally, and thus, important hydraulic characteristics, particularly
near the failure zone, have not been adequately captured because of three-dimensional complexities.
Taking these complexities into consideration, this study conducts a large-scale experiment to examine
the characteristics of wave propagation in an open area caused by a gradual levee failure. From the
experimental observations, this study provides the propagation speed of a wave front and suggests a
formula for the maximum flood depth corresponding to the peak flood wave in the inundation area.
We expect the findings to provide hydraulic engineers and scientists with fundamental insights into
transient flow during a gradual levee failure. By contributing to our theoretical understanding, the
measurements can also be used as validation tools for future numerical simulation and are likely
to contribute to the establishment of emergency action plans that can help city officials cope with
flood inundation.
