We all know that changes watershed development and specifically increased impervious area increases runoff to streams. As a result, these streams adapt by deepening and widening through erosion. Traditional stormwater management methods have focused on controlling run off on site or through regional detention with the hope that restored hydrology will restore streams. The resilient stream corridor approach looks at restoring stream/floodplain connectivity and channel/floodplain complexity directly instead of controlling hydrology alone. This reconnects natural processes that dissipate stream power through increased connected width and roughness. Working with nature to accommodate higher flows whether due to development or climate change. Stream resilience fast forwards stream evolution to a more sustainable natural future state rather than trying to fix in place the streams of the past. Wolf Water Resources is working with CWS to develop a framework to practically implement resilient stream corridors as a hydromodification strategy using the stream power connection. The tool will help CWS assess, quantify, and track urban runoff impacts, identify stream enhancement needs, and evaluate the efficacy of stream resilience measures in offsetting hydromodification impacts.
