GRASS VALLEY, Calif., Feb. 23, 2021 /PRNewswire/ -- 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. Adding to the risk is the aging infrastructure — the average age of levees in the U.S. is 50 years. These levees require regular inspections, maintenance, upgrades, and patrolling for high water. Levee erosion becomes a huge challenge to monitor, often not visible and missed because of what's going on below the surface. As the levee systems get older, inspections and maintenance become more challenging.
"We believe REMS to be a really cost-effective solution that will make it possible to monitor potential levee erosion sites 24x7 and alert key personnel about problems early so they can take timely action," added Ogden.
There are estimated to be about 100,000 miles of levees in the U.S. Two-thirds of the U.S population are in counties that have at least one levee. Thirty thousand miles of levees are documented in the National Levee Database, with 97% of these earthen levees. The U.S. Army Corps of Engineers has responsibility for over 14,000 miles of levees under its Levee Safety Program. A further estimated 85,000 miles of levees are privately owned and operated.
In the last five to six years, the Army Corps has conducted inspections of levees under its Levee Safety Program. With about half of them inspected today, the Army Corps reports that 20% are of moderate- to higher-risk, with bank erosion considered one of the top three risk factors.
REMS is aimed at local levee owners, levee safety authorities, levee stakeholders, states, local governments, tribes, and private entities. Click here to learn more about REMS, Remote Erosion Monitoring System for levees.
