  abstract = {{L}ocalization of buried polyethylene pipes is an important issue for network managers. {T}his study focuses on an acoustic method, which consists of vibrating the pipe and observing the signal with a receiver placed on the ground surface. {T}his method provides an estimate of the path of the pipe but gives no information on the depth. {W}e developed a multi-sensor method based on the principle of vibrating the pipe, which allows estimating the depth while being non-invasive and non-destructive and without a priori information on the propagation medium. {T}hese sensors are positioned perpendicular to the pipe. {W}e developed a new estimator to estimate the depth and the propagation velocity in the medium, which is an important variable in our problem. {T}his estimator is based on the {MUSIC} algorithm and is adapted to our choice of modeling. {I}n this paper, two models of travel times in typical situations are presented. {T}he first one represents the case where all sensors can be placed inside the trench (on the ground surface) in which the pipe is buried. {T}he second one represents the case where sensors are placed inside and outside the trench. {T}hese travel time models aim to provide a fast result to allow the method to be used by field agents. {T}hey are compared with a full wavefield modeling by finite differences.},
