Abstract

The primary function of the river dike system is to safeguard lives and property from flood hazards. However, due to aging infrastructure
and various geological or anthropogenic factors, certain vulnerable sections of the dike system can emerge as the water level in the
river increases. Flood maps are one tool that presents vital information for authorities and residents in the flood risk mitigation. This
study's primary goal is to provide a flood map under the dike break condition using the estimated fracture size parameters from a
geo-radar survey and the MIKE FLOOD model. This approach addresses the observed research gap by utilizing a survey database
instead of relying on empirical models which are capable to produce the conservative estimates of the dike breach outflow. A case study
is conducted on the Hoang Long River dike system in Ninh Binh Province, Vietnam.
