Geotechnical Borehole Imaging at Emsworth Lock and Dam
Supporting lock chamber design on the Ohio River with borehole geophysical logging, subsurface data, and structural analysis for long-term navigation infrastructure improvements.
ARM Group completed critical borehole geophysical logging and imaging work as part of a geotechnical subsurface investigation at the Emsworth Lock and Dam in Pittsburgh, PA. Using portable borehole imaging tools, the team measured the depth and orientation of fractures and bedding planes in over 40 geotechnical boreholes that were drilled in the river with a barge-mounted drilling & logging system. This work was part of the design phase for a new lock chamber at the Emsworth navigation facility, supporting safe and reliable navigation on the upper Ohio River.
Why This Project Matters for Regional Navigation and Infrastructure
Emsworth Locks and Dams is maintained by the U.S. Army Corps of Engineers Pittsburgh District, helping to keep river traffic moving along the Ohio River. Located just downstream of Pittsburgh, the Emsworth Dam creates the navigation pool for the city. Built in 1919, these are the oldest locks on the Ohio River, and upgrades are needed to keep them operating smoothly for years to come.
What ARM Group’s Borehole Imaging Means for Our Clients
ARM’s borehole imaging work helped geotechnical engineers gather key geological information needed for the design of the new lock chamber. Accurate subsurface data helps clients make informed decisions about construction and long-term stability.
How Borehole Geophysical Logging and Imaging Works in a Riverine Environment
By using borehole imaging technologies, ARM measured rock fractures and bedding planes beneath the riverbed. This information will help with the planning and design of improvements that will support river navigation and the movement of cargo from Pittsburgh to destinations around the world.
