Noosa Landfill RRA Flood Assessment



5 PROPOSED CASE MODELLING
The proposed RRA fill pad has been incorporated into the model using TUFLOW z-point modifiers.
The site fill area has been raised to above the DFE flood level and graded to fall northwards.
Details of the proposed case model topography are shown on image 5-1.




Image 5-1 Proposed Case Model Topography


The proposed case ground level assumptions modelled are appropriate for an initial constraints
assessment but will need to be refined as part of future detail design.

Finished floor levels of any buildings constructed on the fill pad will need to achieve the minimum
levels shown on Image 5-2. This will ensure finished floor levels are a minimum of 300mm above
the DFE peak flood levels.
