Nutrient Monitoring

Nitrate, phosphate, and other nutrients are increasingly present in surface waters and can cause problems like harmful algal blooms that adversely affect ecosystems and humans alike. Real-time nutrient monitoring with NexSens telemetry systems offers critical insight into the presence of nutrients and resulting effects on water quality over time.

Stream & River Monitoring

Streamside or in-river water quality data is valuable for research, assessment, regulation, and environmental impact studies. Continuous measurement provides the comprehensive data necessary to draw definitive conclusions. NexSens monitoring systems are designed to simplify the setup and operation of real-time water quality measurement in streams and rivers.

Flood Warning System

Early and effective flood warning can help to protect people and infrastructure when severe weather strikes. By combining non-contact water level measurement technology with reliable wireless communications and solar charging, NexSens flood warning systems are easy to install, operate, and maintain.

Stormwater Monitoring

As stormwater runs off surfaces, it can accumulate and transport pollutants to local waterways. NexSens real-time stormwater systems can be deployed to track both quantity and quality of stormwater runoff, alert for changing conditions, and automatically collect water samples to aid in pollution prevention efforts.

Weather Station

Weather stations alert to current conditions and provide data for predictive models. Specifying and building a research-grade weather station is straightforward with NexSens data loggers and industry-standard sensors. Real-time data telemetry and flexible mounting options facilitate setup and data collection even in remote locations.

Dissolved Oxygen Monitoring

The Federal Energy Regulatory Commission (FERC) and other agencies have established dissolved oxygen limits for hydropower facility operations to minimize dam impacts on the local aquatic habitats. NexSens dissolved oxygen systems offer a flexible sensor, data logging, and communications platform to monitor these levels in near real-time.

Hydropower Plant Monitoring

Hydropower plants are important for energy generation, but their presence dramatically changes the surrounding landscape. There are also many factors which affect plant operation and maintenance. NexSens comprehensive monitoring systems can be implemented at hydropower assets both to reduce environmental impact and optimize operations.

Dissolved Gas Monitoring

Dissolved gases like oxygen, carbon dioxide, and methane are common in surface waters. They play important roles in aquatic ecosystems and impact atmospheric gas concentrations through air-surface flux dynamics. NexSens real-time monitoring systems with dissolved gas sensors can detect acute changes and study long-term cycles and processes.

Sediment Monitoring

Turbidity measurement is commonly accepted as a surrogate for sediment monitoring because it is convenient and relatively simple. However, some cases may call for more precise measurement of sediment concentrations. For these situations, real-time monitoring systems for total suspended solids (TSS) or suspended sediment concentration (SSC) are available.

River Sediment Transport

Sediments are a natural part of river ecosystems, and many organisms depend on them for spawning, habitat, or capturing prey. However, large sediment loads can adversely affect ecosystem health. Sediment transport studies can be used to establish baseline sediment concentrations and monitor for acute and long-term changes.
