the Floodengage program

Floodengage is an engagement decision support system developed by Dr Ray Laine. The intention of the system is to provide a mechanism for stakeholders (community members, councillors, developers, planners, engineers etc.) to learn about, rank and make informed decisions about management options for the Wollongong City Catchment.

How does the program work: 

  1. Experts in flood management produce a list of management options that could be used at the catchment you are interested in and how well each of the options addresses a series of criteria such as cost, timing etc.

  2. By answering the questions in the survey you determine the criteria that you would consider a successful management outcome in the catchment (Step 1)

  3. Based on this input, the program determines which options are most suitable (Step 2). There is accompanying information of why certain options come out on top compared to others

  4. If you are not happy with the results, you can then re-rank the options (hopefully informed about the options advantages and disadvantages) in Step 3.

  5. You can then provide feedback or list other options that might have been missed.There are also some extra questions you can choose to answer that will help the management planners to understand the context of your answers (Step 4).

  6. The information from all respondents is then collated and evaluated by Ray Laine, passed onto the consultant and presented to the Wollongong City Council floodplain management committee for consideration.

  7. Initial feasibility flood models are run to investigate 10 options.

  8. A management plan, with a list of prioritised options is prepared.

  9. This plan is publicly exhibited for a minimum of 28 days allowing further public comment.

  10. If changes are required they are made and the management plan is finalised and adopted by Council.

  11. The plan is then implemented, based on the prioritised options. Usually some options will require further detailed feasibility and design studies to be completed however, some options can be implemented straight away.

  12. The study and plan is typically reviewed and updated following changes in the catchment (i.e a major flood event, significant development etc.) or 10 years has passed since adoption.
