Forecast of geotechnical conditions in the areas of product lines'' Transitions through water barriers

The authors consider the usage experience of the electrical exploration surveys by the engineering geological researches in the water areas in the winter. They highlight the importance of two-level observations - on the surface and on the bottom of the water, - to increase the information content. The authors give the example of successful use of geophysical surveys in the different stages of engineering geological researches. They suggest ways of development in the interpretation of water area measurements.
