Approach and Outcomes
The first step was to upgrade and recalibrate the 2008 MIKE FLOOD model. Then modelling of five structural mitigation options was undertaken. Each option involved combinations of: bridge widening, bridge removal, channel widening, levee implementation and commercial and residential building demolition.
The options were assessed for feasibility, land use considerations, tangible and non-tangible flood damages by SMEC with input from WMS. The primary outcome of the project was a phased implementation strategy detailing property acquisition, preliminary works, staging of construction/demolition and costings. Recommendations for sources of funding were also provided.
