Babinda Constructed Wetland & Plain Rehabilitation
Wetland Design, Rehabilitation Plan, Pollutant Export Modelling
Purpose
As part of the Reef Recovery Program, AWC in partnership with Jaragun developed a strategy and detailed design to intercept sediment and nitrates from a 2000 hectare agricultural catchment.
The works included extensive consultation to win the support of landholders before delivering a constructed wetland and floodplain rehabilitation works despite significant site constraints.
A key challenge was to create a large wetland while minimising earthworks and exposure of ASS.
Objectives
- Pollutant export and water balance models
- Earthworks design
- Hydraulic design
- Vegetation management strategy
- Construction documentation
