Sudden and unexpected flooding resulting from the breach of a reservoir, levee, or
large-volume storage pond can have dire effects on downstream communities and ecosystems.
Recent failures of levees in New Orleans; dam failures in Missouri, Washington, Michigan,
and Hawaii; and the failure of a coal ash disposal pond in Pennsylvania and mine
tailings dams in Mississippi and Florida underscore the hazards posed by dam and
levee failures. Extreme storm events or seismic activity are examples of incidents
that can trigger breaches of reservoirs, levees, and storage ponds.
We are skilled in performing analyses of the risks associated with potential breaches
to develop an understanding of the expected flow paths, velocities, and flood depths
that could result. We utilize state-of-the-art tools and methods to develop numerical
models to simulate breaches and use visualization and animation tools to graphically
illustrate the results of our analysis. In addition, we work closely with our clients
to develop strategies to mitigate flood risks and develop emergency response protocols.
Our project experience and expertise includes:
Safety assessments of dams and embankments
Numerical modeling of flood waters using one- and two-dimensional models
Dam break and levee breach modeling
Analysis of the stability of dams and levees
Flood inundation and hazard mapping
Socio-economic impact assessment and risk analysis
Recommendations for flood warning and communication systems
