INFRASTRUCTURE & SERVICES COMMITTEE MEETING AGENDA                                    16 SEPTEMBER 2014


The feedback from stakeholders acknowledged that the costs of developing a model were
relatively high, however it was identified that the benefits of such a model were:
 That the data would be required in any event to provide supporting evidence for any future
   erosion management works within the river;
 That owning a model avoided the costs of engaging expensive consultancies to provide the
   data; and
 That the data would be available for a range of organisations to use.
The stakeholders also supported the concept of trialling geotextile sandbag groynes at Munna
Point to facilitate sand accretion.
Conclusion
All stakeholders are supportive of the concept of developing a hydrodynamic model for the
Noosa River between Tewantin and the river mouth, therefore further detailed assessment of a
project needs to be undertaken in order to present a proposal for Council consideration at the
next budget review.

Previous Council Consideration
Nil.

Finance & Risk
The projected costs of developing a hydrodynamic model for the Noosa River system between
Tewantin and the river mouth will be in the region of $250,000 to $300,000, with the potential for
recalibration every 5 to 7 years at a cost in the range of $50,000 to $75,000. As these funds
have not been included in the 2014/15 budget, funding would need to be considered at the next
budget review.

The development of the model will enable Council to better understand the dynamics of river
flow, assess the impact of possible solutions for erosion management and therefore mitigate the
risk of further erosion from poorly planned works and the costs of dealing with such problems in
other parts of the river system.
