Dams, Hydropower

Monitoring of dams (including hydroelectric and irrigation dams) is a key operational component to:

· Improve decision making
· Manage risks
· Increase safety
· Increase productivity
· Optimize designs
· Reduce costs

Dam Monitoring – An Overview

  • Water dams, including hydroelectric and irrigation dams, are critical assets for the communities which benefit from them. Often, there are communities or environment downstream of the dam to protect as well.
  • Monitoring of dams allows the asset owner to monitor behavioural changes over time. Should parameters change, they can implement action plans to protect the public and environment as well as maintain usability of the dam for its intended purpose.
  • Due to the number of factors involved (hydrological, geotechnical, structural, and power related), a wide variety of parameters are monitored for dams. These parameters are monitored in the dam structure, the foundation, and the reservoir.

Benefits of Monitoring Systems

  • With an effective monitoring system in place, changes in geotechnical parameters, such as ground movements and seepage, can be detected through early warning monitoring systems. Early warnings allow dam owners to enact contingency plans to counteract the observed changes in parameters.
  • Real-time monitoring systems allow engineers to access data immediately to allow for rapid decision making. Less effort spent on collection of data means more time spent on effectively interpreting and using the data collected.
  • Monitoring instruments provide insight to key areas of concern such as:
    • Ground displacement (settlement or lateral movement)
    • Groundwater levels
    • Seepage
    • Load or stress

The Path to Success – Core Dam Monitoring Components

  • Instrumentation and data acquisition and collection should be selected to suit site-specific conditions and stability concerns.
  • Instrumentation installations should be designed to answer specific concerns in the structure, including the geotechnical parameter to monitor and the location to install the sensor.
  • A variety of data acquisition options are available to meet site specific needs. These can range from manual to fully-automated systems.
  • RST’s Instrumentation Engineers and Specialists can aid in selecting the right solutions for your site conditions.
