Ground Motion And Water Seepage Detection | Rezatec Dam Monitoring

Need to instrument your dam?

Surveys point to movement or subsidence on your dam and instrumentation is your next step. How do you know exactly where to instrument? Can you focus on the highest risk areas to manage cost and maximise results? And how do you pick up ground motion between sensors?

Ground Motion & Seepage

Diagnose movement severity to minimize over-instrumentation and maximize outputs

Instrumentation is often the go-to next step for investigating ground movement. But it’s costly and instrumenting large areas is often beyond the means of many dam operators. In addition, it can be challenging to ensure sensors are installed in the right place and it’s tricky to pick up movement in areas between sensors.

Use Ground Motion & Seepage to diagnose movement trends, compare with your own survey data, determine exact risk areas and prioritise your response before putting resources on the ground.

Pick up motion where your sensors aren't

Ground Motion & Seepage remotely provides a detailed 3-year historical view of structural movement for all your dams – even across inaccessible locations. Using this, it diagnoses normal seasonally expected patterns from anomalous movement, helping you to establish the extent to which movement is an issue. It provides data right across your dam and embankment – giving you a richer dataset than a traditional sensor – providing a scale view of movement and picking up motion where your sensors aren’t. Which means you deploy your instrumentation to the right place, minimize the risk of over-instrumentation and maximize its results.

Dam Safety Engineer, Hunter Water

“Drones just can’t achieve the millimetric accuracy of satellite data. Our comparisons showed drones pick up 20 to 30 millimeters; whereas satellite data detects movement of 1 to 2 millimeters. That’s hugely significant.”

Chief Engineer of the Dam Bureau , New Hampshire Dept of Environmental Services

“Instrumentation installed at the borings cost around $35,000 but doesn’t provide real time readings and requires biannual site visits to download the data. Ground Motion & Seepage helps quantify changes from month to month.”

“Our structures are heavily instrumented, and engineers manually read gauges across the whole dam. We have data gaps and settlement can be missed in visual inspections. Ground Motion & Seepage provides scale total coverage, accurate risk assessment and comparison for our instrumentation data.”

“It costs £300,000 to drill the borings and install instrumentation. With 200-odd dams across the state, this is a massive and costly project. But with Ground Motion & Seepage, we see an avenue for more effective resource.”
