Abstract:Water unsaturated hydraulic conductivity (kw) functions of two remoldedˆne-grained materials were measured over a wide range of degrees of saturation (Sr) with two methods. The instantaneous proˆle method (IPM) was used for Sr À50z. An original vapor equilibration method (also known as the vapor equilibrium technique, VET) was used for Sr º50z. Both materials compacted at the standard Proctor optimum water content and maximum density, have saturated hydraulic conductivities (ksat)º10-7 m/s. The VET couples the… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
