Stage 0 River Restoration

In this webinar we introduce the 'Stage Zero' approach for rivers geomorphological design and assessment of channels.

Why do rivers move, and how far would they go if we didn't constrain them?

**Description** Webinar number 160

We've all carved out channels in the sandbox or at the beach; in this webinar, you get to meet professional fluvial geomorphologists who apply lessons from the sandbox at a much larger scale. Grady Hillhouse from @PracticalEngineeringChannel kicks off the webinar with an overview of stream tables and how they can help us visualise and assess morphological changes. Then a team of experts outline the Stage Zero approach to river restoration.

"Stage Zero" describes a condition in which a river and its floodplain have been undisturbed for a period of time sufficient to allow its geometry to adjust to the flow, sediment, and biological processes of the catchment. Stage Zero is characterised by an abundance of a wide range of hydromorphic attributes and ecosystem benefits, high fluvial complexity, and full connectivity to the floodplain and the hyporheic aquifer.

Early efforts at stream restoration focused on channel-based and form-based methods to add needed habitat elements to degraded stream channels; however, engineered solutions have often failed during large storms, without sufficient consideration of key historic processes. Our invited guests explain the definition and theory of Stage Zero, covering site selection, design, implementation and outcomes, and provide examples of process-based restoration.

surprised to see Grady here but very pleased to hear his simple and concise explanations.

Amazing video, really helped me out with my dissertation proposal! Also been a big fan of Gradys work and have had the pleasure of speaking to Colin a few times, great presentation.
