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…[Click here to download full report]
