McKay's Minimum Energy Loss Culvert

The outflow of Humpybong Creek to Moreton Bay in the City of Redcliffe is the first example – constructed in 1961 – of Professor Gordon McKay’s Minimum Energy Loss Culvert concept.

The design enabled maximum energy conservation through the culvert and resulted in streamlined flow and no buildup of water level leading into the structure.

The MEL concept has been adopted in many situations in Australia and has been favourably reviewed in many international publications. Large savings have resulted in both construction and maintenance costs compared with conventional culvert design.
