Projects

  • HYDROELECTRIC DAM SONAR & LiDAR STUDY

    Underwater Acoustics International executed an above and below water Sonar & LiDAR imaging study of the hydroelectric dam facility utilizing multibeam sonar, side scan sonar and high-resolution scanning sonar. The purpose of this project was to provide a comprehensive underwater 2D and 3D sonar imaging study of the submerged areas of the dam as well as the upstream and downstream areas of the river. The intent of the study was to create a digital baseline of the facility to be use for change over time comparison against subsequent underwater surveys.

  • SONAR SURVEY FOR CANAL LINING CONDITION ASSESSMENT

    The primary objective of the canal lining investigation was to conduct a hydrographic and geophysical survey to evaluate the condition of the canal concrete lining. The UAI team successfully deployed an Unmanned Surface Vessel (USV) with multi-beam sonar and high-definition side scan sonar, proving that sonar is an effective predictive maintenance technology to evaluate the condition of the canal's concrete lining which is inaccessible due to being primarily beneath the water surface.
