Noosa Landfill RRA Flood Assessment



4 VALIDATION
Validation of peak flows at the proposed RRA fill site has been carried out against a Rational
Method peak flow calculation. Details of the Rational Method calculation are provided in Appendix
A. The peak flow comparison shown below demonstrates a good level of agreement between the
TUFLOW results and the Rational Method.


Table 4-1      Peak Flow Validation at Northern Boundary of the Landfill Site

    Rational Method Peak Flow (1% AEP)            12.8 m3/s

    TUFLOW Peak Flow (1% AEP)
    (Critical Duration of 30 minutes)             14.0 m3/s
