what happened to the river in the 1960s-70s
In 1960s the river was completely covered over (because it was considered a health and flood risk)
In 1970s an expressway was built that totally covered the river ( this prevented evapotranspiration , damaged river flows and enclosed the river system)
how did covering the river effect the environment
- virtually no vegetation
- no evapotranspiration
- river totally enclosed preventing evaporation from river and resulting in the only input into the system being from urban drainage systems and water waste
- flow rates were highly IRREGULAR affecting wildlife and sediment balances
- poor water quality
Aims of restoration project
- bring environmental benefits
- ecologically sensitive pedestrian corridor
- dismantle elevated freeway above river
