Flood study

Belongil Creek Flood Study

Belongil Creek is approximately 3km long and has a catchment of around 30 square kilometres. The township of Byron Bay is situated toward the eastern boundary of the catchment with most of the development on higher ground. The transport of catchment runoff to the estuary is influenced by numerous man-made drains and infrastructure. These include the Union Drain, the Byron Bay town drain (or Butler Street Drain), the North Coast Railway line, Ewingsdale Road and numerous bridges and culverts.

Four climate change scenarios were examined during the course of this study:

  1. No sea level change, no increase in rainfall intensities
  2. Lower bound IPCC sea level rise estimate with 20% increase in rainfall intensities
  3. Mid range IPCC sea level rise estimate with 20% increase in rainfall intensities
  4. Upper bound IPCC sea level estimate with 20% increase in rainfall intensities.
