Abstract: The purpose of an Acceptable Flood Capacity (AFC) assessment is to determine whether a dam can or cannot pass the AFC. If not, necessary upgrades and timing must be provided so the AFC is met. It was found that both the Rosewood and Marburg detention basins cannot pass the AFC. They require raising the embankment crest and the installation of a wave wall. In addition to raising the embankment, the Marburg basin needs investigation of various additional spillway configurations. The paper describes the background to dam safety practice in Australia (with particular reference to Queensland), the hydraulic design of these high hazard basins, the basis for determining the AFC of each basin and the way forward.
