Abstract
Dams are an essential part of the irrigation infrastructure, used for water, electricity, flood control, and recreational purposes. Instrumentation in dam safety monitoring is well established. It monitors dam parameters like movements, pore pressure, uplift pressures, water level, seepage flow, cracks, stress and strain, temperature, seismic activity, and weather and precipitation. Different types of sensors are used to monitor the above parameters. These sensors modulate some properties of the light in an optical cable. Fabry-Perot sensors, Fiber Bragg grating sensors, SOFO sensors, and distributed fiber optic sensors are used in dam structural safety monitoring. In this technology, optical fiber acts as a medium for transmitting measurement information. Successful applications of optical fibers prove the maturity of this technology in the dam safety-monitoring field worldwide.
