A more effective way to capture sediment, increase water holding capacity, and expand the floodplain is something called Beaver Dam Analogues. Not sure how much internet resources are out there these days for it, but it is a common “low tech” restoration tool used in the PNW. I am glad to provide more resources upon request. This is something i do for work in my area, and have constructed hundreds.
The basic idea is to use plant material (fir branches are BEST, but most anything will do), and mud/sediment to create a dam that allows water to flow gently & evenly over the top of the structure to prevent scouring & further erosion. When done correctly it requires little maintenance, is very quick and easy to do, and a great way to make use of excess forest material. The majority of plant material & mud is placed on the upstream side of the structure, making sure to create a dense mat of material that ramps up to a “crest” and cascades downstream of the structure evenly.
I am not sure how to attach images, but if folks are interested & cant find good resources on the web, i am happy to figure it out.
