Situational Awareness

The RiverTrak flood mapping tool provides valuable decision making data and risk analysis for emergency managers and other decision makers who work with floodplains. The system increases situational awareness during a flood event, providing a way to assess conditions both real-time and near-future at gages in their area. This technology provides a way to visualize flood risk analysis by measuring progression and timing of a flood event through a time series of real time and forecast inundation maps for multiple gages throughout the stream reach. From the early flood stages of the upstream gage with downstream gages not yet affected, to all gages at flood stage and the gradual recession and return to normal flows.  The ability for this flood mapping tool to visualize extents and depths from current data and incoming forecasts allows for better distribution of resources and a greater focus on flood risk analysis for key areas.

The RiverTrak flood management system incorporates current stage information from gages to show the flood water extents. This is done by using data from gages and determining the relationship of the water to the underlying digital elevation. By using observed gage data, a local digital elevation model and a special hydrologic model, RiverTrak can rapidly produce dynamic flood mapping of inundation. During a flood management event, emergency managers have the latest and most accurate maps for complete monitoring and risk analysis, rather than static pre-processed libraries.

By visualizing depths and inundation in real-time with this flood mapping tool, emergency operations can make informed decisions about their response efforts, including: the efficient allocation of resources and personnel and the safety both the public and responders. The RiverTrak flood mapping tool 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 effective flood risk analysis. Dynamic maps that reflect real-time data improves communications between flood management departments, and between organizations both internal and external to the community during a flood event.

We provide an affordable, accurate, and real-time flood mapping tool that connects early warning, planning, and situational awareness to emergency management systems.
