Kangaroo Valley Flood Study

A flood study of Kangaroo River and its floodplains and waterways was undertaken to determine flood behaviour in and around the town of Kangaroo Valley. The study produced information on flood extents, levels, velocities, and flows for the range of design events including the 20%, 10% 5%, 2%, 1%, 0.5% AEP and the Probable Maximum Flood (PMF).

The Kangaroo River at Kangaroo Valley has a catchment area of approximately 334 square kilometres to the Hampden Road Bridge. The land use is mainly forest and pasture with some farmed crops such as vineyards. The Kangaroo River passes through rugged mountainous terrain and some alluvial flats that is generally used for dairy farming.

Tasks that form part of the Flood Study include:

  • Data collection and review;
  • Hydrologic model establishment and calibration;
  • Hydraulic model establishment and calibration;
  • Simulation of design events;
  • Sensitivity runs of key model parameters;
  • Reporting of flood behaviour; and
  • Assessment of preliminary flood hydraulic and hazard categories.
