Silixa, the world’s leading independent provider of fibre optic-powered data solutions, has updated its website with additional information about embankment dams. Silixa begins the post by describing how a continuous and remote fibre optic-sensing-based hydropower dam monitoring solution can prevent dam failures by providing accurate real-time data on the integrity of the dam. It is a cost-effective solution that enables us to monitor even the largest embankment dam structures in remote locations, thereby providing hydropower monitoring projects with valuable insight.
The post also addresses one of the most frequently asked questions, namely why distributed sensing is used for hydropower dam monitoring in the first place. The distributed sensing technology developed by Silixa transforms an optical fibre into a dense sensor array with thousands of measurement points along its length. Fibre optic cables can be installed in new dams during construction, as well as in existing dams via trenching or standpipes. The comprehensive spatial and temporal coverage provided by the measurements enables the identification of potential failure events in advance.
Seepage detection-based dam monitoring is one of the primary benefits. HydroResearch’s XSeepT is a distributed fibre optic sensing-based, high-precision seepage monitoring system that provides continuous understanding of dam conditions. It uses the ULTIMATM DTS distributed temperature sensor to detect small changes in seepage flow and calculates seepage rates in a dam structure.
In addition, Silixa’s distributed strain sensing (DSS) system provides continuous measurements of the strain applied to fibre optic cable, enabling high-resolution strain monitoring. Movements along the dam can be identified, along with their location and magnitude.
In conclusion, recent advancements in Silixa’s DAS technology, which include both monitoring and analysis techniques, provide an additional method for monitoring the seepage and internal erosion phenomena in dams in order to provide more accurate information regarding their integrity.
