Hydro units are natural laboratory for the study the interactions between climate-permafrost-aquafer. Our geophysical observations, including long-term temperature measurements, near hydro units focused on the study of seepage processes. The aim of the study is to use geophisical information for constructing reliable numerical model of interaction of human impact (hydro units) on the system "permafrost-climate-aquafer". Another part of our work is spatial electric monitoring of the permafrost state near injection wells on oil fields in Western Siberia. We present an experience of such monitoring at a multiple-well platform of an oil field. Changes of permafrost physical state near the injection well investigated using radio wave methods of cross well surveys.
