Elevation of the phreatic surface causes instability of an earth structure. Therefore, drainage system is important on constructing an earth structure. Drain pipe is the drain system applicable even for an existing earth structure. In this study, the drain pipe was expressed in the initial and boundary problems on unsaturated soil. Here, the results of electrical prospecting were compared with seepage analysis on the embankment installed drain pipe. Consequently, qualitative agreement between them was found.
