Stream Design 101
Notes de l’épisode
Concrete channels, buried creeks, and straightened streams simplified urban development but decades later we see the side effects: faster water, steeper channels, collapsing streambanks, and pollution. Manager of Stormwater Design Kristen Buccier and Project Manager Denis Zaharija explain the benefits of more recent, holistic stream design methods.
A stream is a living system seeking stability. Denis and Kristen discuss hydrology and hydraulics, how a stream's bends (or "meanders") dissipate energy, and how riffles and pools create habitat for fish and aquatic bugs. We also learn how “flashy” stormwater volumes can overwhelm streams and how designers work to bring resiliency back to those impacted waterways.
