Estuarine dynamics and acid sulfate soil discharge: Quantifying a conceptual model

A catchment-wide estuarine dynamics approach has been developed and field tested to overcome current limitations. The catchment-wide approach combines onsite investigations with large-scale studies of: (i) the fate/transport of acidic plumes, (ii) the coastal floodplain response dynamics to rainfall or flooding events, and (iii) the objective prioritisation of impacted landscapes for remediation. This paper provides a detailed description of the catchment-wide approach supported by conceptual processes and a detailed case study. The 20 km2 case study site highlights the importance of local and catchment processes in guiding rehabilitation plans.
