Drinkwater Reservoir

Located in Angeles National Forest, an area prone to landslide activity and very active seismically, GeoTDR monitors subsurface movement and pore water pressures and transmit an alert when deformation exceeds alarm level.

I-70 Interchange, Frederick, Maryland

GeoTDR was installed to remotely monitor the I-70 interchange with Monocacy Boulevard and SR 85 where sinkholes are prevalent. A series of moisture probes was also installed beneath the clay liner and geo fabric of the water detention area to monitor for leaks.

I-55 Springfield, Illinois

To continue mining an active coal seam north of Springfield, Illinois the mining company needed to tunnel under I-55 and the adjacent heavily traveled railroad at a depth of 350 feet. GeoTDR was installed to monitor the subsurface movement within the rock overburden and also on the surface along the railroad right of way so the mining company could excavate the tunnels.

U.S. Route 18 Karst Sinkhole Subsidence

To address the issue of sinkhole subsidence along U.S. 18 south of Mason City, the Iowa Department of Transportation selected Time Domain Reflectometry (TDR) as the most cost effective option to monitor for deformation.

McMicken Dam

Due to a high probability of earth fissures developing in the soils underlying McMicken Dam, GeoTDR was installed to detect fissure development and trigger an alert to the AMEC and the Maricopa County (Arizona) Flood Control District.

Tuttle Creek Dam

Due to concern of the U.S. Army Corps of Engineers about the possibility of a seismic event in the New Madrid Fault Zone that could initiate movement of the downstream face of the Tuttle Creek Dam in Manhattan, Kansas, URS Corporation installed a multi-sensor warning system that includes remote monitoring using Time Domain Reflectometry (TDR).

United States Gypsum Company

Concerns about subsidence near an inactive gypsum mine along an existing state highway in Saltville, Virginia led to the installation of a real-time TDR monitoring system.
