Dams and Levees

There are approximately 91,000 dams in the US. In addition, “As of 2019, there are approximately 15,600 dams in the United States that are classified as high-hazard structures” (Dam Infrastructure | ASCE's 2021 Infrastructure Report Card). 

Dams perform vital functions for water flow control, hydroelectric power generation, and water storage for agricultural, industrial, and domestic consumption. They are also used to retain mining tailings, food processing wastewater, and sewage during treatment. Structural integrity of dams is critical to ensure they do not fail. Operators must ensure inlets are clear of trash that could harm the dam flow control mechanisms or power generation equipment. Kongsberg sensors can be deployed on ROVs, surface vessels, or remotely using mechanical deployment systems for persistent or periodic acoustic inspection and to monitor sediment and debris levels. This data provides dam operators and civil engineers with critical information they can use for condition assessment and maintenance planning.

Kongsberg has sensors for measuring biomass in ocean and lake water columns. Navigable river systems do have an environmental impact - they sometimes create an artificial barrier to aquatic species like fish and eels. Kongsberg has environmental sensors that provide scientific data about the water column and the species in it - important data required for today's increasingly stringent enviromental permits.
