what the flood hydrograph would look like
(it can then be used as an input to produce a more accurate inundation models of the breach scenario.In turn, it would make a good input to other models such as the Life Safety Model (LSM) and/or economic valuation of damages.)
Embrea is available online in two versions Lite and Pro. The key features of each version are given in the below table. To purchase a subscription to Embrea Pro, just follow the link below.
The Embrea model currently simulates:
Breach through overtopping of
homogeneous embankments through either headcut or surfaces erosion mechanisms.
overtopping of layered embankments.
a composite embankment (i.e. homogeneous embankment with a core).
Piping failure of homogeneous and layered embankments.
Failure of embankment surface protection (e.g. grass cover / stone rip rap).
Mass failure of breach sides due to slope instability during the breach growth process.
Probabilistic approach to simulating variability in embankment material properties and construction quality.
The erosion below foundation (i.e. scour hole). This feature is currently in development, for more information see our FAQ page.
The model can run in single simulation mode (i.e. run produces only one output) or Monte Carlo simulation mode (i.e. a run produces a probability distribution of the output parameters). The model has been developed to operate within a standard 'Windows' environment and allows for easy handling of modelling data and visualisation of results to provide a flexible modelling tool for determining potential flood risks.
