This paper presents a visual model for analyzing and assessing the potential downstream impacts of flooding that might occur as the result of a catastrophic dam break forced by heavy precipitation. Using high-resolution digital terrain models, transect elevation data, and forecasted water heights at downstream point locations the model provides a geo-spatially accurate, terrain-bounded, time-varying depiction of flood depth and horizontal extent that can be used for decision support across a variety of flooding applications ranging from insurance risk assessment to emergency response. Additionally, a dynamic data inspection capability can provide quantitative temporal and spatial analysis of various flood parameters (e.g., depth) at any point within the flood region. High-resolution imagery, map, and GIS data can also be underlain to the flood data to provide a more complete application context.
