Gravity, nature, weather events, and development can all impact the resilience of rivers and streams. Understanding and applying natural stream form and function is critical to the sustainable management of our stream and river systems.

Whether the goal is to restore critical aquatic and riparian habitat, meet surface water quality goals, develop urban/suburban green corridors and linear parks, or reduce long-term maintenance costs, stream and river restoration is emerging as the best practice for the management of these critical green infrastructure systems.

SWCA’s stream and river restoration staff specialize in fluvial geomorphology, natural channel design, watershed hydrology, open channel hydraulics and sediment transport, bioengineering, and aquatic and riparian biology.
