Let the Water do the Work:
Induced Meandering, an Evolving Method for Restoring Incised Channels
The Mission of Stream Dynamics
Our watershed restoration projects are unique in that we make a landscape scale effort, treating erosion problems in a natural and unobtrusive way. We employ native materials to help watercourses achieve dynamic stability, using deflectors and weirs made of sticks and stones. We put the wiggle back into long, straight gullies by harnessing the hydraulic power of a gully washer to carve meanders into the terraces. This slows the water down, allowing it to soak into the ground and produce the needed sediment to aggrade the channel. For this to work properly, we analyze the harmonic spatial frequency of each reach of each arroyo.
It's about going with the flow.
