So It Flows

So it flows - mock up of people on a boardwalk

By Samantha Godakumbura, Studio: Landscape Architecture


‘So It Flows’ is a nature reserve which is designed around the concepts of decreasing flooding and flood-induced erosion on the Onkaparinga Hills, and the subsequent flooding of the Onkaparinga Washpool.

Visitors can enjoy bushwalking and hiking trails, forested walks with birdwatching opportunities, and views of the valley from skywalks which continue the walking trails across floodgates. A multi-strategy approach is used to reduce rainfall run-off from slopes and slow water flow in channels.

In addition to static methods of flood and erosion reduction, parametric techniques such as sensor operated floodgate barriers and timber logs are implemented which adjust their performance according to the severity of the rainfall event.
