In efforts to rehabilitate tidal wetlands and reduce the impact of acid sulfate soils, restoration projects are being undertaken across NSW. Williams and Watford (1997) stated that >1035 flood gates currently exist that could be effectively modified to restore tidal flushing. With a large number of potential sites and sufficient scientific understanding, tidal restoration projects are currently being undertaken by various groups.
Restoring tidal flushing involves an inter-disciplinary understanding of hydro dynamics, ground water-surface water interactions, water quality / chemistry, ecology, estuarine dynamics and civil engineering hydraulics. Any restoration study should incorporate a staged approach that includes numerical forecasting of hydrological and water quality conditions prior to on ground works and allows landholders to assess potential changes prior to all major tasks. Failure to effectively restore tidal flushing can result in undue flooding, destruction of agricultural crops, salinity concerns, public mistrust etc.
A multi staged management strategy for restoring tidal flushing has been developed.
The eight stages of the strategy include:
- Objective Setting
- Monitoring
- Hydrodynamics
- Sediment dynamics
- Water Quality
- Groundwater
- Ecology
- Coastal Structures
