Environmental flow study on Swan and Canning Rivers

This project involved providing the basis to determine environmental flow objectives and associated river flow regimes for the waterways of the Swan Canning River system for the chapter entitled ‘Environmental Flows’ in the Water Quality Improvement Plan (WQIP).

GHD was commissioned by the Swan River Trust of Western Australia to analyse flow data from 12 representative stations throughout the WQIP area. In particular this involved the analysis of:

  • Surface and groundwater influence on the flow regime of main drains and main tributaries
  • Groundwater influence on surface flow regime
  • Seasonality of the surface flows

In addition, the knowledge gaps encountered during the project were identified and prioritised for future works.
