The IWR Planning Suite is a water resources investment decision support tool originally built for the formulation and evaluation of ecosystem restoration alternative plans; however, it is now more widely used by all USACE business lines for evaluation of actions involving monetary and non-monetary cost and benefits. 

IWR Planning Suite II (Version 2.0.9) was certified by the Planning Model Review Board and was "Certified for National Use" on May 31, 2018.  Versions 1.0.11 and 2.0.6 were certified previously and acceptable for teams that had Review Plans approved with these versions prior to May 31, 2018. (Planning teams should consult with the Ecosystem Restoration Planning Center of Expertise for further questions.)

The Planning Suite has the following features:

  • Plan Generator
  • Cost-Effectiveness and Incremental Cost Analysis  (CE/ICA)
  • Auto reports, graphs, and tables
  • Calculation of annual average non-monetary benefits (v.2.0.6 and higher)
  • Calculation of average annual equivalent costs and benefits (v.2.0.6 and higher)
  • Multi-Criteria Decision Analysis (MCDA, v.2.0.9)
  • Uncertainty Module (v.2.0.9)
  • Watershed Analysis (v.2.0.9)

IWR offers ad-hoc training on IWR Planning Suite.  Various USACE Prospect Courses and other trainings (e.g., Ecosystem Restoration) have also provided training on this software in the past.

Software Version Updates

Update includes minor bug fixes in the MCDA module for displaying graphical results (specifically, criteria contribution to score), corrected Percent of Max normalization method, and corrected version number displayed in the lower righthand corner of the software.

Two bar charts within the MCDA module were corrected.  The charts had the incorrect values for the plan labels.
