Streambank Stabilization By Hand

摘要

Bank stabilization projects commonly rely on large rock, articulated concrete mats or other structural means to gain the mass and stability needed to withstand the forces from high storm flows. Installing these materials usually requires sufficient space for machinery to access and operate in the work area. But what if this space isn't available?rnIn December 2007, flood flows from a 500-yr rainfall eroded 60 feet of streambank along a single-family residence in Seattle, WA. With the residence practically perched over Thornton Creek, the storm flows created a large, irregular void 8 to 10 feet under the main structure, exposing several supporting piers.
