The Role of Electrical Resistivity Imaging in Geotechnical Work
Posted by Sean on Sep 17, 2024
Geotechnical engineering, a fundamental branch of civil engineering, is centered on understanding earth materials and their interaction with human-made structures. Whether designing the foundation of a skyscraper or stabilizing a hillside to prevent landslides, geotechnical engineers must analyze and manage complex subsurface conditions to ensure the stability and safety of infrastructure. As part of this process, Electrical Resistivity Imaging (ERI), also known as Electrical Resistivity Tomography (ERT), has emerged as a critical geophysical tool. ERI provides...

Interpreting RES/IP Data: Tips for Subsurface Characterization
Posted by Sean on May 21, 2024
Every dataset tells a unique story in electrical resistivity imaging (ERI). For experienced professionals and academics, the challenge often lies in interpreting this narrative from the inverted data. This involves identifying important subsurface features such as groundwater, voids, contamination plumes, and other significant aspects.
In previous posts, we discussed the key factors to consider when analyzing groundwater exploration...
Invasive vs. Non-Invasive Subsurface Exploration
Posted by Sean on Apr 05, 2024
Exploring the depths below our feet has historically involved disruptive practices that were dangerous, harmed the environment, and were…well, pretty loud. We know the last one may not seem important, but we think it may have everything to do with today's techniques.
You see, in the span of about thirty years, we had two world wars. As you can imagine, the development and implementation of advanced technologies like radar became a top priority across the globe. Since tactical considerations were a significant concern,...
10 Ways To Diversify Your Services with Electrical Resistivity Imaging
Posted by Sean on Jan 15, 2024
In past articles, we’ve covered many ways industries apply Electrical Resistivity Imaging (ERI) for their benefit. From groundwater exploration to power engineering, and even archeology—we’ve shown the versatility of the electrical methods of subsurface exploration. But what if you don’t fit into one particular sector? Perhaps you’re a consultant or geophysicist for hire. For those who are looking...
How is Electrical Resistivity Imaging Used For Archaeology?
Posted by Sean on Oct 20, 2023
We don’t discuss archaeology nearly enough as it deserves. And since it’s October and Halloween is around the corner—why not talk about the spookier side of geoscience? Okay, archaeology isn’t actually scary—unless you’re claustrophobic (the fear of being in tight spaces) or have cartilogenophobia (the fear of bones), or have mummyphobia (which is what we guess the fear of mummies is called).
But the real reason we want to discuss archaeology is that this year has seen several fantastic discoveries. This past Summer in our home state of Texas, a drought revealed...
The Role of Electrical Resistivity Methods in Power Engineering Projects
Posted by Sean on Aug 14, 2023
We’ve discussed how Electrical Resistivity Imaging (ERI) has served many industries. We’ve covered mining, groundwater exploration, construction, and more. Let’s take a brief look at another industry—power engineering. We’ll explore how electrical resistivity methods impact power engineering projects, focusing on their practical applications...
Exploring Borehole-to-Borehole Electrical Resistivity Surveys
Posted by Sean on Jul 05, 2023
We like to dig into various topics on our blog. One method that we want to drill into today is the borehole-to-borehole electrical resistivity survey.
We’ve broached the subject of borehole-to-borehole surveys a couple of times on our blog. We mentioned it in our post about the Bipole-Bipole array and our Panama seminar recap. The Panama case is fascinating because it utilizes our...
How ERI Enhances Construction Projects
Posted by Sean on May 11, 2023
The beginning stages of any construction project can present various challenges that may affect its success. Addressing these issues early on, from site selection to budget constraints, is crucial. One particular concern is understanding the subsurface geology and potential anomalies that can impact construction. That's where Electrical Resistivity Imaging (ERI) comes in. This blog post will explore how ERI can be a game-changer in construction projects, ensuring informed decision-making, preventing delays, and mitigating safety hazards.

What is Groundwater Discharge?
Posted by Sean on Mar 17, 2023
Groundwater is a favorite topic of ours here at Advanced Geosciences. There is just so much to discuss! Not only is groundwater exploration an everyday use of electrical resistivity imaging (ERI), but understanding groundwater can reshape our relationship with an invaluable resource. This time, we want to look at groundwater discharge and the delicate balance it serves on a global scale.
In short...
Underground aquifers are layers of sediments or fractured...
