Breach Analysis

Carry out detailed and accurate modelling of defence failure

Model in detail overtopping and piping breach failure mechanisms, including how a failure develops and changes over time. Use our 2D TVD solver’s unique features to accurately model the propagation of the flooding that results from a failure. 

Key facts

  • Model dam and levee/embankment overtopping and piping breach failure mechanisms

  • Model how the breach develops and changes over time

  • Flood Modeller's 2D TVD solver provides accurate representation of 2D ‘shock’ (rapid changes in water surface profile), which makes it ideal for breach analysis

  • Helps determine whether a proposed development is safe or not

  • Assesses the velocity, rate of inundation and depth of flood water anticipated

Undertaking robust and accurate modelling of the failure of a defence structure, such as a levee/embankment, which can have significant consequences, enables you to better understand the risks and be better prepared to respond should it ever occur.

Model the overtopping breach of a structure, with the failure emanating from the crest of the structure (open breach) and enlarging over time. Model a piping breach, which starts as a small hole in a structure that enlarges over time and may ultimately collapse into an open breach.

Explore 2D results in the core map interface, overlaid on the built-in background mapping and any other contextual layers. The built-in animation functions enable you to view and record a complete picture of your model results.

Using the 2D TVD solver can help provide an improved understanding of flood extents and travel times of the flood wave. The TVD solver has been specifically developed to be robust and more accurate, than other types of solver, when there are rapid changes in flood depths and velocities. 

The advanced features that you find in Flood Modeller allow you to easily model the impacts of a defence structure failure for events of different flood severity, allowing you to fully understand the flood risks for your area of interest.
