Water Infrastructure Simulation Environment (WISE)

Overview

Flood risk area

The Water Infrastructure Simulation Environment (WISE) is an integrated software framework for modeling, simulating, and analyzing interdependent water infrastructures. WISE allows quick and accurate management and analysis of large infrastructure networks across the dams and water sector. This framework includes the following:

  • Event definition and consequence assessment
  • Simulate urban/regional water infrastructures

Flood Infrastructure Simulation

Objective: Provide capability to quickly and accurately estimate flood risk area from wide range of event scenarios.

Infrastructure Consequence Flood Inundation Tool 2D is a two-dimensional shallow water equations flood inundation model capable of simulating overland flow:

  • Accurate flood estimation applied to wide range of flood events (e.g., dam/levee failure, surge, riverine flooding)
  • Utilizes multicore computing capability for fast-running simulations.
ICFIT-1D

Seamlessly integrated one-dimensional flood model within a GIS:

  • Built-in rainfall-runoff modules
  • EPA SWMM used as the hydraulic model for full dynamic wave simulation (closed or open conduit)
  • Flood risk area determined in GIS

Water Sector Modeling-Building Tools

Many of the infrastructure simulation models developed by NISAC require extensive input datasets that are normally costly to preprocess, making these tools useless in emergency events. To facilitate the preprocessing task, WISE includes tools that take available data and create/convert it into compatible and usable model formats.

Water Distribution Model Builder (WDMB)

WDMB is a GIS-based tool that readily converts water distribution networks into IEISS compatible format:

  • GIS shapefiles to IEISS:
  • Topological inference capability
  • EPANET models to IEISS
Channel Morphology Tool (CMT)

Channel Morphology Tool is a GIS-based tool which builds and converts open channel network models for several hydraulic models, including an IEISS open channel infrastructure solver:

  • Builds\creates both EPA SWMM and USACE HEC-RAS compatible files
