Water level information system

We believe in the need of a global water level information service and enjoy building a meaning- and powerful system. Therefore we’ve been working on FloodAlert in our leisure time next to our jobs since 2014.

Up-to-date & worldwide

We provide most curent water levels from rivers and lakes worldwide.


Next to up-to-date and historical water levels, we use data science and intelligent algorithms to provide forecasts of water levels.

Warning system & API

Our data and services are used to inform and warn people and organisations through apps, Web and high-performance IT interfaces (APIs).


Our goal is the integration, forecast and publication of waterlevels from all water bodies worldwide.
