Little Topashaw Creek - Summary of Findings - Vegetative Control of Gullies |
Vegetated inlets stabilized portions of gullies with moderately sandy soils, but were vulnerable to headcuts more than 0.5 m high that advanced into the gullies from the stream channel. Also, one vegetated inlet that was constructed by shaping low-density sandy silt soils failed during a high flow season with unit discharges up to 0.09 m2/s. Dabney, S., Shields, F.
