Groundwater Seep Identification

For nearly a decade, SelkerMetrics has been an industry leader in the use of DTS technology for the detection and quantification of groundwater emergence into surface water systems. We use proprietary hardware and software to enable efficient and accurate characterization of water movement in a variety of environments, including rivers and streams, lakes, and marine coastal waterways.

Sediment Movement

SelkerMetrics has developed proprietary fiber optic techniques to monitor near real time scouring and deposition at high spatial resolution across large, multi-acre scales. This work often accompanies groundwater seep detection, but can be offered as a standalone deployment. Once fiber is installed, sediment transport monitoring occurs remotely with little to no additional field deployments required.

Streamwater Temperature Monitoring

Mapping and quantifying aquatic refugia is critical to understanding the ecology of streams and rivers.  Identifying groundwater inflows and hyporheic exchange is also important for tracking potential contaminant transport pathways.

Down Well Applications

Distributed temperature sensing is applied to down-hole applications where high spatial and temporal resolutions are needed to study hydrogeological processes. Both passive (un-heated) and active (heated) DTS technology is utilized to study groundwater flow, cross-screen and well in-flows, and substrate thermal properties.

Acoustic Sensing

Distributed acoustic sensing (DAS) is used in a wide array of applications where the desired process to be monitored produces acoustic or vibratory signals. Some examples are perimeter and intrusion security, leak detection in pipelines, storage tanks, and machinery monitoring to detect worn or damaged components. SelkerMetrics designs, deploys, and analyzes DAS-based monitoring programs to help with your sensing and measurement needs.

Fiber optic cable, used with specialized electronics and software, precisely and continuously measure temperature at thousands of independent locations over large areas across extended times.  SelkerMetrics has pioneered the use of this technology for environmental monitoring and hydrogeologic applications. The flexibility of DTS technology provides limitless opportunity for creative approaches to measure and monitor a variety of natural and engineered systems.

DTS technology is used to find underwater groundwater seeps where temperature differences reveal water movement and flow through sediments, allowing DTS technology to locate and quantify groundwater emergences across large areas.  Monitoring is continuous, allowing changes associated with solar input, tides, rainfall/runoff, active pumping, seasonal climate shifts or other variables to be observed.  In addition to groundwater seep detection, sediment deposition and scouring can also be monitored continuously over large areas.

DTS technology is also employed to track water and fluid movement in soils, through man-made caps, and in other geotechnical applications where contaminant flows are of interest.  For example, SelkerMetrics has installed patented cable technology in wells to detect water movement within and near the well, and can detect leaks in infrastructure such as sheet piling and other barriers.

DTS technology can also be applied in situations involving temperature monitoring in air or liquids, and can be used to monitor vibration, sound, and strain over long distances and across large areas through time.
