Underground rivers are underground flowing water that develop in carbonate areas or in water enrichment formations. At present, the underground river detection methods mainly include isotope tracer method, magnetotelluric method, and controllable source audio magnetotelluric method. In this paper, according to consulting a large amount of literature data, a new method of underground river tracing based on strapdown inertial navigation technology is proposed. The inertial device is installed on a floating carrier and the carrier is drifted with river water. The acceleration and angular velocity of the carrier are recorded, and the trajectory of the carrier is calculated by the attitudealgorithm, then obtaining a concrete trace of the underground river. This method overcomes the disadvantages of the traditional measurement methods that are greatly affected by the environment and difficult to measure.
