Wise Up: DSS-WISE™ LITE as an Alternative Method for Breach Analysis and Consequence Estimation

DSS-WISE™ Lite (DSS-WISE) is a web-based, automated two-dimensional dam break flood modeling and mapping tool with the capability of completing dam break analyses via a web-based platform and computing the potential breach inundation consequences downstream of the subject dam. DSS-WISE is a robust numerical model that uses fully dynamic shallow water equations. The numerical model uses a state-of-the-art upwind numerical scheme that can handle all flow regimes, wet/dry interfaces, and discontinuities. The upwind numerical scheme is parallelized dividing and executing the DSS-WISE model computations on multiple computer cores at once. This parallelization supports excellent computational speed, allow for the potential of operational real-time simulations of potential emergencies, and rapid results for multiple simulation runs at a minimum of effort and cost. DSS-WISE also has a Human Consequences Module (HCOM) that calculates an estimation of day and night population at risk (PAR) within the dam break inundation zone. This information is valuable as input into risk informed decision making (RIDM) processes such as semi-quantitative risk analysis (SQRA).
