Department for Environment and Heritage (DEH) commissioned Water Technology to develop a hydraulic model for the Eckert Island section of Katfish Reach to assist decision makers in the development of a number of waterway management options.
A coupled one and two-dimensional hydraulic MIKE FLOOD model of the Katfish Reach floodplain, including the Murray River and the entire Eckert Island anabranch system, has been developed. A thorough calibration was undertaken to ensure the capability of the model to reliably predict hydraulic conditions for different scenarios and management options.
The hydraulic model was calibrated for a range of historic flood events including the 1996 and 2000 events (with peak flows at Lock 5 of approximately 61.5 GL/d and 45.3 GL/d respectively). These historic floods extensively inundated the Katfish Reach floodplain.
This report documents the Katfish Reach floodplain hydraulic model development and presents the results of the model calibration for the 1996 and 2000 historic flood events. [Click here to download the full report]
