Council develops flood studies to improve our understanding of flood behaviour, in particular the speed and depth of flood water, and to identify problem areas.
What is a Flood Study?
It’s a comprehensive technical investigation of flood behaviour for a particular catchment, river or creek. It is the technical part of the floodplain management process. The aims of a flood study are to define existing flood behaviour, including levels and extents, help identify flooding problem areas in the catchment and assess the impacts of climate change.
Flood studies help improve our planning and management of the catchment, such as setting flood levels for development control, improving flood emergency responses and establishing a basis for subsequent floodplain management activities.
What is a Floodplain Risk Management Study?
This is a study to evaluate management options for differing types of flood risk. It assesses different factors such as: danger and damage from potential flooding, community displacement, possible future development, flood risk management options and environmental considerations.
A floodplain risk management study provides recommendations for an appropriate mix of management measures, such as: development controls to reduce the risk of flooding for future development, flood mitigation works (levees, detention basins), improved emergency responses, voluntary house purchase, voluntary house raising, and community education.
What is a Floodplain Risk Management Plan?
A floodplain risk management plan is usually undertaken in conjunction with the management study and the two are integrally linked. The management plan outlines the implementation of management options recommended in the management study. It is based on the considered opinion of the local community and it provides a long-term path of future development for a specific floodplain or catchment.
Step 1 is data collection. Step 2 is Flood Study. Step 3 is Floodplain Risk Management Study and Plan. Final step is Implementation of Plan.
