Fig. 5. Flow-through rates (q₀) for clear water vs. ponding depth of water for: (a) SiltSoxx (SS) using fine compost (see Table 1) for both 10° and 20° slopes vs. depth, (b) SS using coarse compost (see Table 1) for both 10° and 20° slopes vs. depth, (c) silt fence (SF) for both 10° and 20° slopes vs. depth, and (d) fine SS, coarse SS, and SF using regression equations.
