Electrical resistivity tomography method application for groundwater survey in Novosibirsk Region

Despite its relatively low cost near-surface surveys allow for substantial benefit to national economy. In particular, the quickly developing method of electrical resistivity tomography (ERT) finds its way in construction, engineering surveys, archeology and many other domains. A very important but still not very well studied field of ERT method application is hydrogeology. In particular, the problem of aquifers localization is well-suited for ERT surveys as a way to solve it. Fresh water is a valuable resource which can become rare in near future. In some countries its value can already be compared to oil. The problem of finding fresh water sources is old and at first impression -well managed. However with modern technologies we can do even better. This article covers results of efforts aimed to find aquifers by means of ERT surveys. During our surveys we used SKALA-48 and IRIS Syscal Switch Pro devices. Despite these surveys being relatively juvenile at IPGG SB RAS there are already some interesting results which allow make preliminary conclusions on ways and prospects of further development of ERT methods in aquifers exploration.
