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.

The earth dams breach erosion is analyzed using dimensionless analytical Solutions for rectangular breach given by Singh and Quiroga (1988). Data for the historical failure of Teton Dam are used to test these solutions. The calculated changes of breach bottom elevation with time are used for prediction breach outflow hydrograph. The one-dimensional unsteady flow model in reservoir was applied for prediction breach outflow hydrograph.
