Tracking Flow For Hydropower

The Northern Indiana Public Service Company (NIPSCO) is a large energy provider in the state of Indiana. It provides power to more than a million customers through distributing energy derived from natural gas and hydropower dams.As part of achieving its mission to provide reliable energy to its customers, officials at the company have to be aware of changing flow rates near its hydropower assets. The real-time calculations are necessary for keeping plant managers up to speed on factors that could influence hydropower output.To meet the need for quality data tracking flow, officials at NIPSCO contracted engineers at LimnoTech, an environmental consulting company based in Ann Arbor, Michigan, to devise a monitoring solution. Project managers at LimnoTech then collaborated with specialists at NexSens Technology to equip vital hydropower areas with water level sensors and cellular data loggers. Going with the flow

Bridge Scour Monitoring

Bridge Scour Monitoring

Bridge Scour Monitoring

Proper bridge design depends on many factors, including accurate estimates of expected scour around bridge piers and abutments. As water passes through a constricted bridge opening, local accelerations cause scour, and the design of the bridge must account for it. Scour prediction models, however, contain a large amount of uncertainty due to the complexity of the physical processes at work. This is generally accounted for by overestimating expected scour depth to ensure the safety of the bridge. While overestimating scour depth is necessary for safety, it increases the cost of bridge construction.In an effort to reduce uncertainty associated with scour prediction models, the Michigan Department of Transportation awarded a research grant to Wayne State University and Lawrence Technological University to collect field-scale data related to pier scour. The study aims to reduce the cost of bridge construction without sacrificing safety. Reducing uncertainty with monitoring The research team chose their initial site along the Flint River in Michigan. Soil and bridge characteristics, as well as the presence of a USGS real-time flow gauge, influenced site selection. A Tritech Micron Echo Sounder measures the depth to the riverbed, and a NexSens AccuStage vented pressure transducer measures the changes in water level.

Flood Warning Systems

Flood Warning Systems

Flood Warning Systems

Flooding is impossible to avoid completely. And as extreme flood events continue to increase in number and frequency, more communities are vulnerable.Flood warning systems help communities of all varieties cope with this growing threat. An early warning can make the difference, saving property and lives. The Importance of Flood Warning Systems Of course, some regions are more likely to experience flooding than others. However, flood warning systems should be installed close to any important waterway. These flood alert systems generate critical information that can guard against property damage and loss of life.
