River Water Level Monitoring

River Water Level Monitoring uses existing riverside cameras to watch water levels continuously. Its Water Level Rise Detection reads the water line against fixed reference points and raises an alert when levels climb toward a threshold you set. Alerts reach duty staff while there is still time to act. It is built for flood control centers, municipal public works teams, and infrastructure operators responsible for rivers, culverts, and low-lying roads.

VLM output

An elevated fixed camera looks down on a swollen river carrying fast, turbulent brown floodwater past a rocky midstream bar, with the adjacent poplar plantation on the far bank already submerged. Across the four frames the water level rises slightly and the flow spreads further over the eroded near-bank terrace, progressively covering rocks and debris that were exposed earlier.

Customer challenges

1

Staff must watch camera feeds or drive to gauge sites to judge how fast a river is rising.

2

Overnight and storm-period rises can go unnoticed until water is already near critical points.

3

Physical gauge sensors are costly to install and maintain across many scattered river locations.

4

Without a clear record of how levels changed, teams struggle to justify or review closure and evacuation decisions.

Customer benefits

Duty teams learn about a rising river early enough to close roads and warn residents.

One operator can keep watch over many river locations at once instead of a handful.

Sites already covered by cameras gain level monitoring without new in-water hardware.

Every alert comes with the camera view behind it, so decisions can be checked and explained later.

Key features

Before & after

Before Operators scan live camera walls to spot a rising river. After — with Linker AI Nexa The system watches the water line and alerts only when it rises.
Before Overnight rises are found at the next shift change or site visit. After — with Linker AI Nexa Monitoring continues through the night and notifies duty staff on the spot.
Before Crews drive to riverside sites to read gauges during heavy rain. After — with Linker AI Nexa Level status arrives from the camera, keeping crews out of harm's way.
Before Road closure calls rest on scattered reports and personal judgment. After — with Linker AI Nexa Calls rest on a threshold alert and the camera view that triggered it.
Before Adding a monitored site means installing and maintaining in-water sensors. After — with Linker AI Nexa Adding a site means pointing the software at a camera already there.
