Flood studies

Flood management

Local councils in New South Wales are responsible for managing flood-prone land. We work with the Department of Planning, Housing and Infrastructure to develop flood risk management studies. These studies help us understand the risks of flooding and develop strategies to reduce those risks.

The NSW Flood Risk Management Manual outlines a process to manage flood risk in NSW.

A flood study is the first step in the flood risk management process. It is followed by a flood risk management study and a flood risk management plan. These studies develop detailed strategies to reduce the risks of flooding.

A flood study is a technical project that uses historical data and computer models to simulate flood events. The study identifies the depth, velocity, and extent of flooding. It also maps the areas that are most likely to be flooded.

The results of the flood study are used to inform planning decisions through a flood risk management study. They can help us identify areas that are not suitable for development and to develop strategies to protect people and property from flooding.

How flood risk management studies can be used

  • To identify areas most likely to be flooded. This information can be used to develop zoning regulations that restrict development.
  • To develop flood maps. These maps can be used by property owners to assess the risks of flooding.
  • To develop flood mitigation strategies. These strategies can include measures such as levees or dams.

Flood Risk Management Process

Data Collection

Compilation of existing data and collection of additional data. Usually undertaken by consultants appointed by Council.

Flood Study

Defines the nature and extent of the flood problem. Usually undertaken by consultants appointed by Council.

Flood Risk Management Study

Determines options in consideration of social, ecological and economic factors relating to flood risk. Usually undertaken by consultants appointed by Council.

Flood Risk Management Plan

Preferred options are publicly exhibited and subject to revision in light of responses.  Formally approved by Council after public exhibition and any necessary revisions due to public comments.

Plan Implementation

Implementation of flood response and property modification measures (including mitigation works, planning controls, flood warnings, flood readiness and response plans, environmental rehabilitation, ongoing data collection and monitoring).


Studies are completed as grant funding and resources become available.
