Wattles vs. drainage blanket
Wattles vs. drainage blanket
(OP)
I have a site with a newly constructed 50 foot long 3:1 slope. Rills are forming from overland flows from a 5 acre mildly graded area above it that is overtopping the crest that is about 600 feet long. Wattles seem like they be an option, but I'm not sure if the application is appropriate to protect a slope that is getting flows from above I haven't found any information if there is a cfs/ft flow rate that would be a max or something like that. At what point are wattles inappropriate, and a drainage blanket would be needed, or is it just a cost analysis once you start needing so many wattles? Are there any references that can be recommended?

A fetch of 200 ft will typically initiate channelized flow. If the land above the top of slope is 200 ft or greater such channelized flow will gully the slope face - especially if the slope is denuded. Slope drains can help with that. If the fetch is less than 200 ft, you may still need slope drains.
How to manage stormwater in the completed works assumes the ground has been stabilized. It seems you are dealing with ground that is not yet stabilized.
Then again, maybe I don't quite understand. . .
