Demonstration of Dss-Wise Web, A Web-Based, Automated Dam-Break and Levee Breach Flood Modeling System

The National Center for Computational Hydroscience and Engineering (NCCHE) at the University of Mississippi has been developing and operating the Decision Support System for Water Infrastructural Security (DSS-WISE) Lite and DSS-WISE Web since November 2016. With funding from FEMA, DHS S&T, and others, this simple and easy-to-use tool has been relied upon by over 1,600 users from the dam safety community to submit over 50,000 simulations. Most simulations can be set up in under 5 minutes, and detailed, GIS-compatible results are available within 30 minutes for 87% of cases. This tool has been designed to allow users to get a first-level analysis of flood inundation, flood arrival time, and Human Consequences (HCOM) for prioritization and screening using only a minimum set of inputs without requiring them to obtain expensive software, servers, or numerical modeling expertise. The system uses an automated data preparation procedure to input into a verified and validated numerical model running behind a secure web-based portal for setup and results access and download. This live computer model demonstration will show simulation setup and results visualization and querying along with an explanation of the easy-to-use web interface that saves users the trouble of downloading data, setting up a numerical model, or running simulations on their own.
