Hi,
I'm designing a geosynthetic cover system for a coal waste pile with 8% side slopes of about 200 m long with kind of a domed shape. The site will be vegetated with native grasses. I'm trying to figure out what the potential for erosion on the grassy slope would be so I can figure out if we need erosion protection, or to reduce the design slope. I don't know how to calculate that. As far as I can tell, it would depend somewhat on the soil I'm using, the compaction of the soil, the type of grass etc., but I still haven't found a formula to calculate it with. I've looked at RUSLE and USLE, but those seem to be for agricultural applications in the US. I'm in Canada.
Any assistance would be appreciated.
