The objective of the study was to define the nature of the following two types of flooding that are experienced at the township of Molong for flood frequencies ranging between 20 (1 in 5) and 0.2 (1 in 500) per cent Annual Exceedance Probability (AEP), together with the Probable Maximum Flood (PMF):
➢ Main Stream Flooding which occurs when floodwater surcharges the inbank area of Molong Creek, Reedy Creek, Boree Hollow, Moss Hollow Creek and Foys Creek. Main Stream Flooding is typically characterised by relatively deep and fast flowing floodwater but can include shallower and slower moving floodwater on the overbank of the aforementioned creeks.
➢ Major Overland Flow, which is experienced during periods of heavy rain and is generally characterised by relatively shallow and slow-moving floodwater that is conveyed overland in an uncontrolled manner toward the abovementioned watercourses.
The findings of the study will be used as the basis for preparing the future Molong Flood Risk Management Study and Plan (Molong FRMS&P) which will assess options for flood mitigation and prepare a plan of works and measures for managing the existing, future and continuing flood risk at Molong.
