Horizontal welling is a common method for the laying of the pipelines. This technology requires detailed exploration of first 20-30 m of subsurface for searching the optimal path for the welling tools and minimization of the damaging risks. Situations when the pipeline trace crosses the river are very common. In such a case, it becomes necessary to explore geological cross-section just under the river and in the surrounding area. Usually this task is being solved using the following methods: seismic, vertical electrical soundings, electrical resistivity tomography and ground penetration radar. In this paper we discuss the case study of application of the controlled-source radiomagnetotelluric (CSRMT) method for near surface exploration in winter period along the pipeline path which cross frozen rivers.
