Eonfusion’s multi-dimensional data structure and dedicated flood module have been tailored to produce an effective tool for modelling the spatial and temporal dynamics of flood waters. Eonfusion’s Flood Model can be used to effectively simulate river flooding events, controlled water releases, dam breaks and the impact of mitigation structures to the flow of flood waters. The Eonfusion flood model leverages graphics processing technology (GPU) and smoothed-particle hydrodynamics algorithms to model the passage of flood waters flowing over digital elevation models (DEM) in an interactive environment.
