A geomembrane cap is used to prevent rainwater infiltration into a closed landfill. Above the geomembrane, a 1.5cm thick geonet is used as a lateral drain to convey rainwater that has passed through the overlying cover soil. During a large rainstorm, the geonet drain was flowing full. The hydraulic gradient was 0.15, and the flow exiting from a 1m wide section of the drain was measured at 0.9m3/min. Based on this information, what is the transmissivity of the geonet, in units of cm2/sec? Calculation work required. Cover Soil Geonet Geomembrane Drainage Flow
