Claim:
1. An apparatus for measuring saturated hydraulic conductivity of unsaturated porous media comprising: a measuring tube disposed in a longitudinal direction such that a portion thereof is buried in a foundation, the measuring tube having a hollow portion therein extending in a top-bottom direction to contain a portion of porous media in an unsaturated zone of the foundation, the measuring tube comprising a first hydraulic head side connecting portion and a second hydraulic head side connecting portion on lower portions, the first hydraulic head side connecting portion being spaced apart from the second hydraulic head side connecting portion, and a first flow rate measuring-and-connecting portion disposed above and spaced apart from the first hydraulic head side connecting portion and the second hydraulic head side connecting portion; a Mariotte's bottle disposed on a ground, the Mariotte's bottle containing water therein with both ends thereof being closed, the Mariotte's bottle comprising a second flow rate measuring-and-connecting portion connected to the first flow rate measuring-and-connecting portion, wherein the Mariotte's bottle supplies a predetermined flow rate of water to the measuring tube through the second flow rate measuring-and-connecting portion in response to air being supplied to an interior thereof; a first hydraulic head observation tube and a second hydraulic head observation tube respectively fixed to the first hydraulic head side connecting portion and the second hydraulic head side connecting portion and extending upward; and a flow rate measuring tube connecting the first flow rate measuring-and-connecting portion and the second flow rate measuring-and-connecting portion.
