Clywedog dam in Wales, UK
UK’s largest water dam has been instrumented with four MENHIR systems in order to permanently monitor its dynamic behavior induced by vibrations and ground motion.
While 3 MENHIR are installed at critical locations across the dam, a 4th high-dynamic range MENHIR serves as a free-field reference for quickly evaluating the dam’s response spectra. The wireless network installation avoids expensive lightning protected cabling.
