Overview
Water Technology undertook a quantitative assessment of geomorphic behaviour of Mullaroo Creek and the Lindsay River, in order to investigate the potential impacts of a proposed system of weirs and regulators.
Numerical hydraulic models developed investigated how the proposed structures and their operation will affect the properties of flow and hence the physical form of the rivers. Using such quantitative analysis the impacts of the proposed scheme on the geomorphic processes of sediment transport, bank erosion, bank slumping, floodplain scour and floodplain deposition were analysed.
The objectives of this study were to provide Mallee Catchment Management Authority with knowledge of the key geomorphic issues and the degree of intervention required to manage Mullaroo Creek and the Lindsay River.
