Dams
Instrumentation and monitoring of dams and reservoirs are important concerns in dam engineering. At each stage of investigation, planning, design, construction and operation in dam engineering, instrumentation and monitoring are required to monitor the behaviour of engineering points.
For the safety and normal operation of a dam, precise information is required from instrumentation and monitoring of dam’s body, the surrounding foundations and reservoir.
Different kinds of instrumentation and monitoring are required for the different types of dam.
