Development of innovative cost-effective autonomous telemetric early warning system for detecting floods, mudflows and rockfall initiation

 
 
 

Project background

Flashfloods, rapid mudflows and rockfalls occur in most countries in the world, including Europe. They can cause gross damage and heavy human losses: as was the case in recent catastrophic events in Germany, Poland, Hungary, France, Italy etc. According to the new data, catastrophic events have occurred more and more frequently over the last decades due to global climate change.  Georgia, France and Moldova are prone to such catastrophes. Flashfloods, mudflows and rockfalls Early Warning Systems (EWS) can save many lives and reduce damage. Existing EWS systems for such events are as a rule expensive. Development of effective and cost-effective telemetric autonomous EWS is very important, especially for developing countries, which are most vulnerable to hydrogeological catastrophes. Creation of such systems became possible last years thanks to development of compact, precise and very cheap high-tech devices (MEMS, Arduino) or through the use of low-cost optical cameras and open sources processing libraries (e.g. structure-from-motion).
