Dam & Reservoir Technology

Cliff Face Survey, Lake Powell

The above image, shows a surface map of a dam area with sonar below water & laser data above

3D Sonar Rock Trap Survey

Our 3D sonar unit was deployed without shutting down the water flow.

Shows the size shape and volume of debris

Trash Rack Survey

In some instances a specific sonar profile indicates additional information that may be helpful, or shows unexpected anomalies or features. For this reason selected profiles may be included in the report.

Inundation Studies

Collect accurate water volumes with sonar. While above water laser profiles can calculate volume changes with rises in water level.

Ideal for water inundation studies.

Sonar data showing concrete spalling on a dam face.

Our 3D, high resolution scanning sonar produces high definition CAD ready data. This may indicate scour patterns, position of construction joints, and type and size of debris. A mosaic of these images can be overlaid on a 3D wire mesh surface.

Tunnel inspection data

Using profiling sonars the percentage of flow restriction can be calculated. Tunnel diameter, volume of build-up, damage, turbulence or other information is also provided as a table.

Along with the data tables, we use high resolution video cameras to produce highly detailed frame grabs for our reports.

Inspection Class ROV

Our 1000 feet depth rated remotely operated vehicle (ROV) has a high resolution camera as well as scanning and profiling sonars a fiber optic umbilical ensures video quality. The ROV is capable of two knots under water.

Video

The high resolution digital video camera can be used to capture images of scour areas, sink holes and trash racks. A system to introduce dye can be implemented to test for water currents.
