A tool designed for use within system-risk models.


AREBA was designed for use within system risk models and uses analytical expressions for the erosion rate, in combination with a pre‑defined breach shape to predict breach hydrographs and changes in breach dimensions.

When to use this tool? 

AREBA has a run time of less than one second and is therefore ideal for use in scoping studies, or probabilistic studies where numerous model runs are required. 


How to use the tool

The AREBA tool is available to developers for incorporation in system risk models.  In addition, HR Wallingford can undertake specialist consultancy for you using this tool.  Please get in touch to discuss.
