Determining the hydro-ecological effects of abstraction in the Mount Lofty Ranges, South Australia (#208)

The flow regimes of rivers in the Mount Lofty Ranges are intermittent. Coupled with this, wide spread extraction for agricultural use has altered these flow regimes, increasing the spatial and temporal extent of disconnection.  Water allocation plans seek to balance use between the environment, social and economic concerns. Determining the amount of water required by the ecosystem to sustain ecological communities and processes requires a multidisciplinary approach. Previous methods of determining environmental water requirements have focussed on geomorphic reach types coupled with hypothesised responses of key taxa. Our work seeks to further the current approach by using data driven methods to determine the ecological effects of water extraction, classify the flow regimes based on hydrological parameters and model future responses to varying levels of extraction.
