Understanding a river ecosystem requires some background research and knowledge. River systems are complex entities with many influencing factors. Have a fly around the catchment using our premade fly around Google Earth for Chrome below. This will help you understand land use upstream of our study site.
Look through the Prezi and the PDF document on Natural Resource Management issues below and utilise the web to answer your pre fieldwork questions.

Floods
The Hawkesbury Nepean River Catchment has a history of flooding. Most of the flooding occurs downstream of the Grose River confluence at Yarramundi. The largest flood on record occurred in June 1867 when flood waters reached approximately 12 metres higher than the deck of the present-day old Windsor Bridge when the Windsor Flood gauge reached 19.7m. Many lives were lost during this flood. The 2020 floods were the first time in over 20 years that the river flooded across the deck of the old Windsor Bridge. The Windsor Flood gauge registered 9.2m. For a list of major floods dates and heights view Major Historic Floods at Windsor Data.
Even higher floods are possible with an estimated high flood level of 26m at the Windsor gauge.
