Rand Flood Study

Rand is located within Federation Council, approximately 40km southeast of Urana and 17km northwest of Walbundrie. It has a population of 204 people (2016 census) and is located adjacent to Billabong Creek. The creek runs along the south-western edge of the village and under Four Corners Road. The village on the upstream side of this crossing is located on high ground and is generally free from flooding in Billabong Creek. Downstream of the Four Corners Road crossing, the village area near Rand Hotel is serviced by an earth embankment levee along the western side of Mahonga Road, almost to Five Mile Road. The levee is approximately 900mm high with a crest less than 1m wide.

Flooding in Rand occurs primarily from Billabong Creek and the village has experienced several major floods including June-July 1870, July 1891, October 1917, June-July 1931, July 1956, October 1974, September 1983, and most recently October 2010, February 2011 and March 2012. The highest flood for this reach of the Billabong Creek was the 1931 flood. During the 2012 flood, about 8 properties were affected by inundation and houses were threatened, but there were no residences with above-floor flooding in Rand. Access to Rand, however, was cut off in the 2010, 2011 and 2012 flood events. Intense storm events may cause nuisance flooding in the village.

The primary objective is to define the nature and extent of flood behaviour in and adjacent to Rand village. The study will produce information on flood levels, velocities, flows, hydraulic categories and provisional hazard categories for 20%, 10%, 5%, 2%, 1%, 0.5%, 0.2% annual exceedance probability (AEP) events and the probable maximum flood (PMF) event.
