hydroGEOPHYSICS Dam Assessment

Every dam is unique and so is HGI

Dam Assessment is a signature service and geophysical resource page developed by hydroGEOPHYSICS Inc, (HGI). At HGI, we understand that every project is unique and we have developed specific geophysical technologies to match the distinctive needs they require. We provide tested and trusted approaches and high quality services to deliver cost-competitive, actionable solutions, safely and on time. We are exceptionally passionate about geophysics, and our mission is to help clients realize the powerful information geophysical technologies offer to mitigate the risk of future failures.

Understanding a dam’s integrity and locating potential points of failure are core objectives for protecting these critical assets

Dam Assessment Site

Many dams throughout North America are aging, and the risk of breach for downstream communities is ever increasing. Thus, having the capability of understanding each structure’s integrity and locating potential points of failure remains a core objective for protecting these critical assets.

HGI’s Dam Assessment website is designed to help earthen dam, levee, and tailings dam owners and operators appreciate how geophysical technologies can assist them with understanding the internal integrity of these structures. We have a broad work history within the industry and have developed a complementary set of tools to map, track, and monitor water movement within these large earth-engineered structures.

To this end, HGI has developed electrically-based geophysical methods with innovative cabling systems, GPS, and unique analytical methods to assess the reliability of dams and levees. Our methods can identify areas of concern related to abnormal seepage or piping, in order to aid mitigation efforts against failure.

An Internal Image

Every earthen containment system is unique in design, construction, and use, and these properties present challenges in assessing reliability and risk. Getting a holistic inside view of the structure in the context of its design and construction is the ultimate goal of understanding its integrity. HGI has adapted geophysical characterization methods to offer such a view by using electrical resistivity, seismic, and streaming potential (SP) methods to create an internal picture of these complex structures. These innovations provide data-rich information sets, thus creating a catalyst for conveying solutions that would be unrealized without it.

Our geophysical innovations provide data-rich information sets that can help drive managers to solution-ready, actionable results.

There can be a variety of sources for seepage and groundwater contamination. For example, in this figure a source of contamination due to a high volume of inorganic waste stacked as a wet slurry, has seeped through the subsurface. This is an example of using geophysical data to chase a seepage path - HGI mapped the horizontal and vertical seep pathway and solution migration.
Why Select HGI
