  • Field Analytical and Site Characterization Technologies: Summary of Applications

    Abstract This report provides information about experiences in the use of field analytical and site characterization technologies at contaminated sites drawn from 204 applications of the technologies listed below. For each technology, information is presented on the reported uses of the technology; including the types of pollutants and media for which the technology was used; reported advantages ...

  • Assessing seepage flow conditions through a dam quickly and accurately without drilling or drawing down the reservoir

    This paper examines the application of a proven geophysical technology that is highly effective in assessing seepage flow conditions through, beneath and around earthen embankments. The technology works rapidly with minimal disruptions to dam operations—it requires no drilling or draining of the reservoir. It has become a competitive solution to many of the complex challenges faced with dam ...

  • White paper - RaMPS technology explained

    1. Introduction RaMPS, which stands for Resistivity Mono-pole Profiling and Sounding, is a unique and proprietary geophysical survey and exploratory methodology developed by Willowstick Technologies by combining traditional resistivity sounding and profiling techniques into an integrated surveying method. It is not only unique in the way the data is acquired, but unique in the ...

  • Willowstick surveys are applicable and affordable on small projects

    Over the course of Willowstick's eight-year history, we have had the opportunity to work with many prominent clients on large, complex projects. As a result of this, many potential clients have had the perception that Willowstick is "expensive" and not suitable for smaller, less complex projects. While it is generally true that Willowstick's rates might not cost the same as more traditional ...

  • Assessment of geo-hazard potential and site investigations using Resistivity Imaging

    The use of geophysical methods for evaluating subsurface contamination of sites is becoming increasingly popular all over the world. The paper presents the assessment of geo-hazard potential of a site in the City of Duncanville, Texas using Resistivity Imaging (RI). Resistivity Imaging was being used to identify areas of environmental concern and to develop a detailed image of subsurface ...

  • CETO 6 - Albany (WA) Project

    The Albany Wave Energy Project commenced in 2017 and intended to build, deploy and operate a prototype CETO 6 Unit. The Western Australian Government committed $15.75m in funding which was subsequently withdrawn and the project has therefore ceased. Despite this, valuable work was done on developing one of the world’s most attractive sites for wave energy. Vessel ...

  • Use of Electromagnetic Induction Tools in salinity assessment/appraisals in eastern Colorado

    Abstract Electromagnetic induction (EMI) is a relatively low-cost and rapid method for measuring, assessing spatially soil salinity. The two studies were conducted to evaluate data obtained with a single-frequency (EM38 meter) and multi-frequency (GEM300 sensor) EMI instruments and to relate apparent conductivity measured by these instruments with the more conventional ...
