Major floods in Victoria in 2010, 2011 and 2012 resulted in significant damage to, or loss of, fences installed close to rivers and creeks.
This raised issues about the type, design, construction and location of fences on active floodplains, and about the usefulness of funding riparian works, such as fencing on floodplains that can be damaged during floods.
Consequently, guidelines were developed by DELWP in collaboration with catchment management authorities (CMAs), and other stakeholders to help choose the best techniques for siting, designing and constructing fences in flood-prone areas. This will help ensure that the maximum benefit is gained from the resources applied to riparian fencing.
These guidelines help choose fencing for a riparian area by:
- Providing a key to identify the type of floodplain;
- Explaining the range of fencing options for that type of floodplain; and
- Giving the information needed to decide on the most suitable fencing option (or options) for the site.
The guidelines detail three strategies for minimising floodwater and debris damage to fencing:
- Avoiding flood impact;
- Making the fencing flood-resistant; and
- Making the fencing flood-resilient.
Choosing the right strategy for a site requires striking a balance between capital, recurrent and repair costs and what is appropriate for different land uses.
