Wind Tunnel Study of ClosureTurf Landfill Final Cover System
This paper presents the results of wind tunnel tests of the ClosureTurf landfill final cover system. ClosureTurf is a synthetic turf closure system that services as the hydraulic barrier to separate the waste and protect human health and the environment. It consists of a structured geomembrane, an engineered turf, and a specified infill. Wind tunnel testing was conducted on a scaled landfill model constructed with a 3H:1V slope on one end, a top deck, and a 4H:1V slope on the other end. The pressure distribution along the closure system surface was measured using pressure taps. Wind tunnel tests were also conducted on an exposed geomembrane surface. The measured pressure distribution along the exposed geomembrane surface was compared to that along the closure system, as well as the semi-empirical solution by the widely accepted Giroud method. The results of the wind tunnel tests can be used in engineering practice to evaluate whether the closure system has sufficient ballast to protect it from wind uplift under a design wind speed.
