WHAT ARE DAMS AND HYDROPOWER PROJECTS MONITORING?
WHICH ARE THE CHALLENGES IN DAMS MONITORING?
The challenges of geotechnical, structural, and hydrological dams monitoring programs are to assess and manage risks related to the physical stability, safety, and efficient operation of the dam. This can include:
- Deformation: monitoring of deformation is crucial for detecting movements or changes in the dam structure that may indicate instability or damage. Such monitoring includes measurement of vertical and horizontal movements, tilts, and rotations of the dam and its components.
- Seepage: monitoring of seepage is essential to detect any leakage or water flow through the dam’s foundation, embankment, or abutments. The monitoring includes measuring water levels, flow rates, and groundwater pressure, among others.
- Internal erosion: monitoring for internal erosion involves detecting voids or cavities formed due to the internal runoff of soil or rock within the dam. Such monitoring includes measurements of piezometric pressures, settlement, and deformations.
- Foundation stability: monitoring of the foundation stability involves measuring the movements of the foundation, assessing its strength, stiffness and deformation capacity. Such monitoring helps to detect the potential for foundation instability that could lead to the dam’s failure.
- Structural integrity: monitoring of the dam’s structural integrity involves regular inspections and non-destructive testing to detect any tilt, cracks, or other damage to the dam’s components. Such monitoring helps operators to identify and remediate issues before they become significant threats to the dam’s stability.
