A geotextile is used as a filter behind a genet drain in a reinforced slope. The grain size distribution of the retained natural soil is shown in Figure 8.22. The soil's permeability is measured to be 4.8×10-4 cm/sec. Select a geotextile that meets the soil retention, drainage, clogging resistance, and survivability criteria and its type (woven or nonwoven).
