Shared Vision Planning through
Computer Aided Dispute Resolution
Stacy Langsdale, P.E., Ph.D.Institute for Water Resources, USACE
www.SharedVisionPlanning.us
Water resource planning & management is characterized by…
• Persistent conflict
• Complexity & uncertainty in natural systems (hydrology, ecology, climate change)
• Conflicting interests & values
• Interest groups and the public demanding involvement

Integrated Assessment (Rotmans and van Asselt 1996)
• Place problem in broader context
• Assist with trend analysis
• Assess alternatives
• Framework to structure knowledge
• Translate uncertainties into risk
• Identify research gaps
3:50
Participatory Integrated Assessment
• More science does not eliminate uncertainty
• Post-modernist view: science is subjective
• Participants define value-based parameters
• Involvement of the client helps to keep work relevant to their needs

Shared Vision Planning
Researchers The Community
10:15
Shared Vision Planning builds:
• understanding of the system
• confidence in the analysis
• trust among parties
10:45
Leading participatory planning & management requires:
Technical Tools• Understand basic
hydrology, ecology, economics, etc
• Accurately represent the linkages between these areas
Process Skills• Understand
institutional setting• Determine ways to
engage Stakeholders• Build trust

System Dynamics
• Developed by Jay Forrester at MIT in 1950’s.• Contrast to Reductionist approaches• Applied to Business Mgt, Urban Planning, and
Global Modeling (Limits to Growth)• STELLA, ModSim, Vensim

System Dynamics Principles (Richmond, 2004)
• 10,000-Metre View
• Dynamic Thinking– Events -> Patterns -> Causes
• System as Cause

SVP along the Rio Grande: process and products

•Snowmelt driven system•Most water originates in the north •Majority of demand in the south
•Human water use•Surface water use by agriculture (senior)•Groundwater use by municipalities (junior)
•Management challenges•Fully allocated and limited supply•Endangered species habitat•Surface water deliveries to Texas•Unsustainable groundwater use by cities•Growing population•Drought prone
•Established technical analysis tools•URGWOM: Daily timestep RiverWare based operations, accounting, forecasting and planning surface water model•ET Toolbox: USBoR product for ET estimation•MODFLOW: 3 regional gw models

SVP along Rio Grande system in New Mexico
•New Mexico water planning process:•16 planning regions• Each tasked with developing a regional water plan
•2002-2004 SVP used in “Middle Rio Grande” region:• Model used to help develop regional water plan.• Seeking low cost and sustainable sw and gw use.• Annual timestep, spatially lumped.•SVP process with non-technical group.
• 2004-2007 next generation of the model• Desire among water managers for more spatial and temporal resolution in a rapid “screening” and public outreach tool.• Monthly timestep, spatially resolved and extended• SVP process with technical group in order to incorporate physical processes as represented by existing analysis tools.

Municipal water use has historically been supplied 100% from gw.
Indoor municipal water use goes to wwtp and from there to river.
Essentially all outdoor municipal water use is lost to atmosphere.
