Approach and Outcomes
The total area modelled and mapped was 20 km2 utilising a single direct rainfall TUFLOW hydraulic model. A two day site visit and field reconnaissance was carried out to ensure that the available information was representative of the conditions on the ground. The TUFLOW model included all pit and pipe stormwater infrastructure. A total of 20 maps were produced in ArcGIS including mapping of the peak asset flow rate and filtered overland flood extents.
