The NexSens G2-RAIN Alert System is a self-contained rain monitor with an integrated precision rain gauge and real-time data alerts. It transmits accurate rainfall measurements directly to WQData LIVE’s cloud based data management platform using internal power and an embedded cellular modem. Paired with WQData LIVE’s configurable alerts, users are notified of rain events directly on a mobile device or computer. Historical rain data can be viewed, graphed, and downloaded from WQData LIVE for additional analysis.

Integrated tipping bucket and MAST mount features create an easy to setup and simple to maintain monitoring system which can be installed and relocated in minutes. Devices can be configured directly from any web browser without the need for costly site visits and complicated connections.

The G2-RAIN’s included Tipping Bucket Rain Gauge with Siphon, uses a standard 8” (200mm) diameter receiver that adheres to WMO & NOAA criteria. The siphon allows a steady flow of water to the tipping mechanism in order to provide reliable readings in 0 to 27” (700mm) per hour rain conditions. The collector funnel comes with a stainless steel filter screen to reduce manual maintenance by preventing leaves and other debris from clogging the opening.

*To ensure reliable data transmission, confirm the availability of Verizon 4G service at deployment location.

River Management On a Changing Planet

River management is inherently complex, demanding mastery of constantly dynamic conditions even when the climate is stable. As the climate changes, however, river management will become even more difficult and unpredictable—and old models and techniques are likely to fail more often. Now, researchers from around the world are calling for attention and change to how we manage and model the rivers of the world. Dr. Jonathan Tonkin , a Rutherford Discovery Fellow at New Zealand's University of Canterbury , spoke to EM about why he is arguing that current tools for river management are no longer enough as even historical baseline river ecosystem conditions themselves are changing. Dr.

A Floating Environmental Stewardship Classroom Visits Ohio

This summer a new way to learn about water recreation—and environmental stewardship—paddled into Ohio. With the help of the Toledo Metropolitan Area Council of Governments (TMACOG) , the US Environmental Protection Agency's (US EPA's) Urban Waters Program brought the Wilderness Inquiry Canoemobile “floating classroom” to Toledo for a few days. TMACOG Water Quality Planner Sara Guiher spoke to EM about the programming and the experience. “In August of 2018 we spoke with a representative from US EPA Urban Waters,” explains Guiher. “We received funding through them to bring programming to the area focused on urban water resources. The person that we talked to from US EPA suggested Canoemobile, which we had never heard of.

Restoring Native Brook Trout in North Carolina

The North Carolina Wildlife Resources Commission ’s Inland Fisheries Division has been working to restore brook trout in the state. Coldwater research coordinator Jacob Rash, who works with the brook trout team technicians on this project, spoke to EM about the work. “In North Carolina, brook trout are our only native trout species,” explains Mr. Rash. “With that come biological and ecological considerations as well as cultural importance. A lot of folks here grew up fishing for brook trout with their relatives, so it's an important species that we work to try to conserve. We've done quite a bit of work to figure out where those brook trout populations are and what they are, in terms of genetics.
