HydroMaster
high-resolution rainfall data service to minimize impacts to your operations and assets

Get an edge on severe weather
HydroMaster empowers you with access to the very latest high resolution precipitation radar in real time, updated on a continuous basis. With radar-based nowcasts paired with multi-model deterministic and probabilistic forecasts up to 15 days in advance, you can be assured of timely and accurate information to support your operational decisions.
To give users an indication of rainfall event severity, forecasts put in context using a dedicated severity index which takes into account both location and season.
With HydroMaster you not only know what’s coming but also when, where, and the expected impact.

Customized to your needs
Customized to your needs
Within HydroMaster, add your catchment areas, zones of interest, hotspots and rain gauge data to obtain localized precipitation observations and forecasts within seconds.
Evaluate how significant the impact will be for your area by comparing with return periods, and take appropriate measures.
Additionally, integrate with sensors by KISTERS or other makers.
Tailored warnings and alerts
Tailored warnings and alerts
There’s nothing arbitrary about these forecasts.
Combine past, near real-time and future precipitation data to generate automated warnings when criteria are met.
With a few clicks, identify hotspots or catchment areas of interest. Conveniently upload polygons from your GIS platform.
For timely and effective dissemination of warnings you decide who, how and when messages will be issued.
Once HydroMaster knows interests, it automatically calculates precipitation totals and forecasts — and you simply access your results as maps, charts and tables.
Archived data for deep understanding
Archived data for deep understanding
View and analyze past rainfall events using the same tools available in real-time mode.
Save your work in comprehensive post-event analytical reports with various pre-formatting options.
For post event analysis, review past alarming events. A rich set of statistics including storm analysis with return periods are presented during recorded alarm conditions and storm events.
The NowCast feature would have bought 3 hours of warning time, time that would have been very useful to assess risk, options, and make proactive decisions.
