The Gold Coast area has a reputation as a flood prone area, even without considering the effects of global climate change.

The Gold Coast area comprises seven major catchment areas including the Tallebudgera, Currumbin, Nerang River, Coomera River, Pimpama River, South Moreton Bay, Sandy Creek and Broadwater area (Mirfenderesk, 2009). The Nerang River catchment is adjacent to the Tallebudgers catchment to the South. It is bordered by the Broadwater and Coomera River area to the North. The Nerang River catchment is adjacent to the Pacific beach area as well (Mirfenderesk, 2009).

Catchment areas have different levels of tolerance before the concentration of water to sediment reaches saturation levels, creating the likelihood of flooding in the area. The Tallbudgers, Currubin, and Broadwater area have time concentrations of approximately 3 hours, creating conditions favorable to short duration local flooding (Mirfenderesk, 2009). The Nerang River and Coomera catchments have time of concentrations from...
