From Flood Detection to Real-Time Warning
How We Can Help You
Flooding is one of the most dangerous and costly hazards impacting transportation networks and communities. Increasing event frequency, aging infrastructure, and limited resources are making it harder for agencies to respond effectively and keep people safe.
Campbell Scientific delivers a complete portfolio of early warning solutions, enabling agencies to detect hazards early, automate warnings, and support coordinated responses. From large-scale flood monitoring networks to targeted roadside warning systems, we provide the flexibility to match your operational needs.
Contact UsDetect, Warn, and Respond with Confidence
Monitor rising water levels at low water crossings, flood-prone roads, urban underpasses, and river systems. Reduce risk and prevent dangerous roadway incidents.
Automated alerts for immediate action
Trigger flashing beacons, message signs, or control systems the moment thresholds are exceeded.
Ensure consistent, real-time warning without delay.
One platform, multiple hazards
Extend safety across your entire network. In addition to flooding, systems can detect and warn for:
- Low visibility (fog, smoke, dust)
- High winds and crosswinds
- Icy or hazardous road surfaces
Our Early Warning System Solutions
ALERT/2 - Network-Scale Flood Warning Systems
Designed for regional and national flood monitoring, ALERT/2 systems provide real-time data and decision support for emergency management and hydrology networks.

- –Scalable networks from tens to hundreds of monitoring sites
- –Integration with emergency operation centers and modeling systems
Typical Applications
- –River and watershed monitoring
- –Community flood warning networks
- –Emergency management and evacuation planning
- –Water resource and hydrological monitoring
Mission-critical infrastructure for flood detection and response
SurfaceSentry Warn - Targeted Hazard Warning Systems
Designed for site-specific hazard detection and driver warning, the SurfaceSentry Warn provides simple, cost-effective systems for immediate, localized response.
Key Capabilities
- –Flooding, water level, or other hazard detection at a single location
- –Automatic activation of warning signs, beacons, or gates
- –Solar-powered, low-power, autonomous operation
- –Configurable from simple stand-alone systems to connected solutions
- –Optional cloud connectivity, cameras, and remote control
Typical Applications
- –Flooded roadways and low water crossings
- –Urban flooding and underpasses
