Health Assessment of Dams by Geophysical Techniques

Condition assessments of embankments and dams is critical for ensuring their safety and operational integrity. Geophysical investigations offer non-invasive techniques that are essential for evaluating condition of these structures. Methods such as Electrical Resistivity Tomography, streaming potential, seismic refraction tomography, and Ground Penetrating Radar (GPR) provide insights information about seepage paths, internal erosion, and structural anomalies.

The integration of these geophysical methods creates a comprehensive framework for the health and condition assessment of embankments and dams. By employing a combination of techniques, engineers can obtain a holistic view of subsurface conditions, facilitating informed decision-making regarding maintenance and rehabilitation efforts. As the demand for reliable water management systems continues to grow, the role of geophysical investigations in dam safety assessments will become increasingly significant, ensuring the longevity and safety of critical water infrastructure.
