Decision Support System for Water Infrastructural Security (DSS-WISE)


What is DSS-WISE?

DSS-WISE is an integrated software package, which combines a state-of-the-art 2D numerical flood model and a series of GIS-based decision support tools. It is designed for water infrastructure safety studies. DSS-WISE can be used to simulate dam/levee breach floods, fluvial floods, storm/tidal surges, landslide waves, and their consequences. It was designed to eliminate scientific and technological gaps of the current flood simulation and flood damage evaluation practice, and to improve current engineering and decision-making practice by providing simulation and analysis capabilities with unprecedented realism and robustness.

Developed by researchers at the National Center for Computational Hydroscience and Engineering (UM-NCCHE) of the University of Mississippi, DSS-WISE has three principal modules:

1) a GIS-based preprocessor and Graphical User Interface (GUI) for problem setup and input data preparation; 2) a 2D numerical model, called CCHE2D-FLOOD, that can handle mixed flow regimes and wetting and drying; and 3) a GIS-based post processor with modules for flood mapping and consequence analysis. The GUI is programmed as an extension of ArcGIS by ESRI. The user carries out the operations using specially designed toolbars providing required functionalities. DSS-WISE allows setting up and performing simulations with various levels of data availability using the GIS-based GUI.
