IWR Planning Suite

**Please go to or to find the latest versions of all software and training materials.**

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. 

There are currently two USACE Planning Certified versions of the model: Versions 1.0.11 and 2.0.6

Version 2.0.9 is has been reviewed by the Planning Model Review Board and was approved for certification in April 2017.  An official memo for model certification is pending.

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.  The software is also introduced in several sessions of existing USACE Prospect Courses (e.g., Ecosystem Restoration, Economic Analysis in Planning).
