Design a needle-punched nonwoven geotextile for use

Reference no: EM13305070

Use Task Force 25, Carroll, and Giroud methods, respectively, to design a needle-punched nonwoven geotextile for use in a laterial drainage layer of a landfill final cover system. The geotextile is placed between a soil protective layer and a geonet as a filtration layer. Typical properties of a needle-punched nonwoven geotextile. The thickness of geonet is 0.2 inch (5 mm). Assume the maximum inflow rate is 0.14 inch/hour. The liquid head over the geomembrane liner is 2 inches. The index properties of the soil placed over the geotextile are as follows: 21% soil particles passing No. 200 sieve; D85 = 3.7 mm; PI = 16
