News | Monitoring rivers digitally

Bosch System issues flood warnings

In many regions around the world, climate change is also changing the weather: researchers expect more frequent floods due to heavy rainfall. Until now, water levels in rivers have been measured with mechanical tools, which means that it can take several hours for data to be passed on to third parties. The new flood monitoring system that Bosch recently presented at the CES could be a game changer. The innovation can digitally monitor the water levels of rivers close to cities in real time, and thus provide timely warnings of oncoming floods. In a pilot project along the Neckar close to Ludwigsburg, Germany, Bosch is currently carrying out a pilot project to test the new system, which is based on two approaches. Both monitor changes in water levels, water velocity, and flow capacity.

Measurements with a camera or soundwave

The first solution operates with a Bosch Security Systems camera that is installed on the river bank. It takes pictures of the body of water every few seconds and transmits them to a mini-computer, which then sends them to the cloud via a mobile phone network. The second solution hangs upside down under a bridge and uses ultrasonic waves. A sensor by Clever Sensor Integration, a start-up company, transmits ultrasonic waves three times per minute. The sensor uses the signal’s duration to assess the distance to the water surface, and can thus measure the water level. Via the long-range network, an integrated mini-computer transmits data to the cloud. The right approach – whether with cameras or ultrasound sensors – depends on the application.

Analysis in the cloud

With an image recognition algorithm, the Bosch IoT Cloud analyzes data within seconds. “Based on the image, the algorithm can tell how much water levels have increased or decreased. Once the analysis has been completed, the data is stored in a database,” says Danny Heber, Senior Solution Architect at Bosch Software Innovations. If a critical level is reached, the municipal authorities or the residents concerned receive a signal via SMS. As a result, they can initiate measures in time to protect themselves from flooding or flood damages. Communities that often face flooding, for instance in India and South America, have already expressed interest in the solution.
