Edward River at Deniliquin Flood Study

The Edward River is located in the Riverina region in the south-west of New South Wales. The River is an anabranch of the Murray River, running parallel to it for approximately 380 km before re-joining it at Wakool Junction. This study concerns the section of the Edward River in the Deniliquin Council Local Government Area, which is approximately 100 square kilometres and has a 19 km long section of the Edward River and its floodplain. The river travels in a general north-west direction through the area, which varies in elevation from 80 mAHD to 100 mAHD. The area, like much of the Riverina region, is characterised by its very flat terrain, containing mostly agricultural and pastoral land. The town of Deniliquin (population approximately 8,000) lies on both sides of the Edward River, and has a number of properties in the floodplain itself.

This report is divided into five sections:

  1. Background. Describes the study area and the previous studies undertaken.
  2. Available Data. Lists and summarises the previous work done in the study area.
  3. Flood Frequency. Describes the methodology used to determine the design discharges.
  4. Hydraulic Analysis. Describes the hydraulic model that was established for this study, including calibration, design flood results and sensitivity analysis.
  5. Review of Flood Risk. Outlines the types of risk assessed as part of the current study, including hydraulic hazard, hydraulic categories and flooding at points of interest.
