Stormwater Monitoring

With increasing large storm events and decreasing permeable surfaces, stormwater can run off surfaces at greater velocity bringing pollutants and other debris with it. There are physical solutions for mitigating runoff such as retention ponds, permeable pavement, and more. With real-time monitoring systems in place, water managers can track potential issues before they affect source water.

A NexSens stormwater monitoring system commonly includes a rain gauge with open channel flow meter wired to a data logger equipped with wireless telemetry. Stormwater monitoring efforts can reduce response time in the case of an exceedance or event with 24/7 access to data and SMS alert options.

Airport Stormwater Monitoring

The Federal Clean Water Act and National Pollutant Discharge Elimination System require that the Greater Orlando Aviation Authority use pollution prevention and abatement techniques at the Orlando International Airport. To meet the goals of the Clean Water Act and ensure the effectiveness of its stormwater pollution prevention plan, the airport has developed a stormwater monitoring program that includes a network of water quality and water level monitoring devices at strategic water resource locations around the airport.

Acton Lake Aquatic Classroom

Located just minutes away from Miami University in Oxford, Ohio, the tranquil and accessible Acton Lake is the perfect training ground for undergraduate and graduate students studying limnology. Not only is it close to campus, it also has a large watershed that makes it responsive to environmental disturbances and a long-term data set for reference. The reservoir serves as the emergency drinking water supply for the city of Oxford, is a productive fisheries site, and has been the subject of ongoing research for decades. Because the watershed around Acton Lake is predominantly used for agriculture, the streams and rivers that flow into the lake can bring in large concentrations of sediments and nutrients during storms, stimulating harmful algal blooms, hurting fisheries, and reducing the lake’s water quality.

Washington Dam Hydrology Tracking

Near the small town of Concrete, Washington, there’s a dam on the Lower Baker River holding back its water. The dam is owned by Puget Sound Energy, a company that delivers electric power and natural gas to customers in the U.S. Northwest. For some time, the hydrology surrounding the dam has been of interest to engineers at the energy company who oversee its operations as part of a hydroelectric asset. In particular, they want to know how water moves in soils and rocks around the Lower Baker Dam.
