Flood Early Warning
RiverTrak real-time mapping includes mapping for near term National Weather Service forecast stage information from gages to show future extents. This is done by using data from gages and determining the relationship of the water to underlying digital elevation. By using forecast gage data, a local digital elevation model, and a special hydrologic model, RiverTrak amplifies flood early warning systems to rapidly produce dynamic inundation maps. Prior to an event, you will have the latest and most updated forecast models and not just static libraries.
By visualizing depth and inundation using flood forecasting models, emergency operations can proactively make informed decisions about the use of resources and the safety of both their own personnel and the community. The RiverTrak maps can be imported as layers into existing GIS technology. Inundation maps can be integrated with a community's existing demographic and structural layers to assess areas of critical concern for a flood early warning system. Having dynamic maps that reflect forecast data improves communication between departments, as well as between organizations both internal and external to the community during a flood event.
Real-time flood inundation mapping shows observed and forecast inundation maps. Notifications in a flood early warning system based on forecast threshold values can be configured to send directly to phone or email and are a valuable element of early warning. Hydrographs that show forecasting models in context of a time series are present on all maps as a method of navigation. The forecast inundation maps also include point and click depth and include both local gage data and observations.
We provide an affordable, accurate, and swift mapping system that connects a flood early warning system with extra planning and situational awareness for emergency management teams.
