RiverTrak real-time mapping provides valuable decision-making data for emergency managers during a flood event. The ability to visualize extents and depths from current data and incoming forecasts allows for better distribution of resources and a greater focus on the areas at most risk in a flood response.
The RiverTrak disaster 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 inundation maps. During an event, emergency managers have the latest and most accurate maps for their flood response plan, rather than static pre-processed libraries.
By visualizing depths and inundation in real-time with this disaster management system, emergency operations can make informed decisions about their flood response plan, including: the efficient allocation of resources and personnel and the safety of both the public and responders. 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. Dynamic maps in this disaster management system reflect real-time data, thereby improving communication between departments, and between organizations both internal and external to the community during a flood event.
Real-time flood inundation mapping comes with observed and forecast inundation maps as part of an overall flood response plan, including notifications based on threshold values sent directly to phone or email, hydrographs, and point and click inundation depths.
We provide an affordable, accurate, and real-time flood mapping system that puts the power of early warning, planning, and situational awareness in the hands of the user.
