A drill rig will start work near Cobden dog park next week as part of WCRC’s work to explore nature-based solutions for reducing flooding in Lower Cobden.
Two monitoring bores, known as piezometers, will be installed to measure groundwater levels and assess the influence of tides on water levels within the Lower Cobden basin.
WCRC Area Engineer Paulette Birchfield says the investigations are part of a wider project looking at whether the basin could be used to provide additional floodwater storage and help reduce flooding in the surrounding residential area.
“The proposed nature-based solution aims to make better use of existing low-lying land to temporarily store and slow floodwater during heavy rainfall thereby reducing the volume of water reaching vulnerable areas at peak times.
“Understanding groundwater levels and tidal influences is an important first step in determining how much additional flood storage capacity could realistically be achieved.”
The information collected will help inform the feasibility and design of potential flood mitigation options.
