The inspection process may begin with the use of sonar to create a detailed map of the underwater topography surrounding the dam. This can help identify any anomalies, such as underwater obstructions or changes in the sediment that may impact the structure of the dam.
Next, an ROV may be used to visually inspect the surface of the dam, as well as any underwater components such as the dam’s intake and discharge structures. The ROV can also be used to take close-up video and images of the dam’s surface and any areas of concern, allowing for a detailed assessment of the dam’s condition.
Throughout the inspection, data and images gathered from the ROV and sonar are analyzed by a team of engineers and inspectors to evaluate the overall health and safety of the dam. Any areas of concern or potential issues are documented and reported to the appropriate authorities, who can then take action to address any identified problems.
