CA - High Sierra Electronics Announces Innovative New Remote Erosion Monitoring System for Levees

Today, High Sierra Electronics (hsierra.com), a Grass Valley, California-based, manufacturer of environmental monitoring products, announced a new system that can detect when and where levee erosion has occurred and automatically alert and inform levee owners, managers, and public safety officials.

The system, known as REMS, short for Remote Erosion Monitoring System, uses a series of beacon sensors that are embedded at levee sites that are prone to erosion. If erosion occurs and washes the bank away, the beacons immediately transmit their status.

The REMS is being tested for the first time for a Levee Safety project, funded by a CA DWR Grant, on the Sacramento River 35 miles north of Sacramento, in a multi-agency collaborative effort to help detect erosion early and alert the levee owners. The sites chosen for the project are at vulnerable locations along the river where erosion occurs very quickly.

"We developed REMS to address one of the major safety risk factors associated with levees, and that's erosion and the potential for levee failure and flooding. With increasing populations in leveed areas, the lives and property of those living behind the levee can be at great risk," said Tom Ogden, Product Manager. "At High Sierra Electronics, our expertise for the past 29 years is real-time monitoring using sensors and telemetry. We put these to use in public safety and warning systems and we looked at how we could apply similar technology in this application where there are clearly some major risks," he explained.

Most of the nation's levees are earthen embankments constructed of sand or soil which can erode easily due to the long-term effects of seepage and saturation, overtopping, and fast-flowing water. While today's new levee systems are designed and constructed to high engineering performance standards and guidelines established by the U.S. Army Corps of Engineers, many existing levee systems were not built to current standards.
