Decision Support System for Water
Infrastructure Security Human Consequence Module (DSS-WISETM HCOM) is an analytical module for automated assessment of the human consequences of dam-break floods. The National Center for Computational Hydroscience and Engineering and University of Mississippi developed the module with funding provided by FEMA through a contract with Argonne National Laboratory.

DSS-WISE™ HCOM uses the results of flood simulation using DSS-WISE™ Lite to provide

maps of:

•
Flood
hazard risk for people caught outdoors and indoors.

•
Potentially
lethal flood zones (PLFZ) for children and adults.

DSS-WISE™ HCOM also provides analysis
of People at Risk (PAR) by interfacing the results of flood simulation using
DSS-WISE™ Lite with the population data sets:

•

2010 census block data from
U.S. Census Bureau, and

•
LandScanUSA
gridded nighttime and daytime population data from Oak Ridge National
Laboratory.

DSS-WISE™ HCOM produces a PDF final report,
an MS Excel worksheet with tabular data, and a series of geospatial files
(raster and polygon shapefiles). These are used for preparedness and emergency
response planning, and evacuation planning.

DSS-WISE™ HCOM is accessible 24/7 to
registered users from FEMA, federal agencies and state dam safety offices via
the web portal DSS-WISE™ Web at https://dsswiseweb.ncche.olemiss.edu/.
