These are just a few of the ideas civil engineering students presented to industry professions in Bendigo today. The research undertaken by students as part of their honours-year studies.
Civil engineering students Dechlan Birt, John Cowell and Lachlan Pittaway looked into whether a water storage facility could be constructed directly beneath the Bendigo Creek.
They were looking for new ways the Bendigo Creek could withstand the kinds of floods that take place once every 5 or 50 years.
'With urban sprawl increasing and more erratic weather patterns due to climate change, we need new ways to convey water downstream in a safe and sustainable manner,' said Mr Birt.
Mr Cowell said the storage facility would need to be roughly 100 meters long, 15 metres wide and 5 metres deep.
'It would be placed directly beneath the creek's bluestones, from View St to Park St in the CBD. When the creek isn't flooding you could store storm water for use in parks, gardens and recreational reserves.'
While the investigation revealed the cost to install and maintain the aquifer made it unfeasible at present, further research or further onset of climate change could make it a viable option in the future.
'The worst outcome would be for the creek to burst its banks and that is what we would try to avoid from occurring,' Mr Pittaway said.
Engineering lecturer Dr Bandita Mainali said students had criss-crossed the state.
'One team is finalising a series of recommendations for the City of Greater Geelong, which struggles with structures like footpaths and roads shifting in the soil.
'Across most of Geelong the soil is rich in a mineral called montmorillonite. When this soil's saturated with water there's a risk any roads or footpaths sitting on top of it will move or sink.'
