Flood Warning System

Flood warning systems near any major waterway or body of water provide critical information that can protect property and save lives. Developing a flood warning system requires attention to three basic factors: data collection via gaging, data processing, and the dissemination of flood warning information.

NexSens automated flood warning systems can utilize radio, cellular, or satellite telemetry to transmit data to the WQData LIVE cloud in real-time and disseminate alerts via email or SMS text message. By combining non-contact water level measurement technology with reliable wireless communications and solar charging, flood warning systems are straightforward to install, operate, and maintain.

Case Studies


Flood Alert System

In an effort to catch and hold floodwaters in the Plum Creek watershed in Lockhart, Texas, a system of lakes, ponds, and spillways was built beginning in the 1950s. The system allows water to be released at a controlled rate, minimizing damage from heavy rains. The Plum Creek Conservation District monitors, maintains, and improves this system to ensure it works properly, maintaining 28 flood control structures and managing underground water resources in parts of both Hays and Caldwell counties.

Stream Gauging Network

Coal mining can have a number of impacts on the surrounding environment and is therefore one of the most extensively regulated industries in the United States. In 1977, the federal government enacted the Surface Mining Control Reclamation Act in response to the negative land effects of coal mining. Coal producers must go through a complicated process for obtaining local, state, and federal mining permits. SMCRA requires reclamation plans for future coal mining sites; these plans must be approved and permitted by federal or state authorities before mining begins. As of 2003, more than 2 million acres of previously mined lands have been reclaimed in the U.S.

Real-Time Rainfall and River Water Quality Data

Located in southwest Ohio, the Edge of Appalachia is the largest privately owned nature preserve in Ohio and provides critical habitat for rare species of plants and animals. Ohio Brush Creek, a tributary of the Ohio River, runs through the preserve and is home to several species of endangered freshwater mussels. To document long-term trends in water quality and rainfall on the preserve, a monitoring system was installed that allows real-time collection of data. This real-time connection, supported by NexSens data loggers and software, allows the preserve to “take the pulse” of the creek for the benefit of students, visitors, and researchers.
