Flood Impact Assessment

Water Technology was commissioned by Browns Consulting on behalf of Armstrong Creek Developments to document the flood behaviour of the Armstrong Creek Western Precinct for the development of Stages 1-6. Stages 1-6 were under construction as part of the multi stage development. The study detailed the hydrologic and hydraulic analysis of the study area in existing conditions with Stages 1 – 6 included. Water Technology undertook modelling using RORB and MIKE Flood packages to ensure that no adverse flood impacts are caused as a result of construction of stages 1-6.

A comparison between pre-development, current (stages 1-6) and full development was undertaken showing that the inclusion of Stages 1-6 have very little impact on flood conditions when compared to previous modelling of both existing and developed conditions.
