Here is a compilation of time-lapse footage of nine different locations around the Hawkesbury district, showing the effects of the October floods that struck us recently. Each location has had up to a week’s events compressed into under thirty seconds, comprising ~64,000 frames run together.

 

Shown in order are:
• Wiseman’s Ferry Road looking towards Cattai Public School
• Yarramundi Bridge near the confluence of the Grose River
• Sackville Ferry
• Webbs Creek Ferry (west side)
• Windsor Bridge
• North Richmond Bridge
• Wisemans Ferry (north and east)
• Webbs Creek (east)

 

I took images from Live Traffic NSW‘s cameras at key locations and mapped them to flood-height information from the Manly Hydraulics Laboratory and the Bureau of Meteorology.
In some locations, gaps caused by low light or missing images are removed.

 

I think this is an original and fascinating way of seeing the effects of what turned out to be a mild-to-moderate flood on different parts of the district. Of interest is the ‘double dip’ in several locations and the increasing effect of tides as you get further downstream.
