 We have an outstanding issue with regard how friction is
 modelled which is not yet resolved.

 will present a series of scenarios for a range of return events to
 assist FESA in developing appropriate plans for a range of event impacts.
 The software tool, ANUGA, has been used to develop the inundation extent
 and associated water height at various points in space and time.
