Project Need
• Freshwater resources modelling is a key tool supporting environmental policy, planning and resource management in New Zealand
• Increase in number of available freshwater models over the last decade
• Increase also in confusion and concern about how these various models relate to one another and could work together

Confusion & Concern
• Lack of knowledge about what models are available and what they do
• Concern that we have too many models
• Models tied to certain providers
• Large expense associated with connecting data &models
• Large investment required to modify existing models or to build new ones
• Uncertainty around how to use model results for decision-making
• Lack of re-use
• Lack of co-ordination among modelling efforts

Response: IFM Project
• ScientificDevelop a prototype interoperable modelling framework to proof-of-concept stage– Interoperability– Adaptation and re-use– Freely available– Ease-of-use– Technologically nimble
• Policy, Planning & Resource ManagementEnable coordinated and efficient explorations of linkages, interactions and impacts among land use,land management, climate change, and water resources

Methods
• Inventories– Existing interoperable modelling frameworks– NZ Water Resources Models– Relevant data (e.g., climate, soils, water, etc.)
• Model visualisation tool (ModelVis)
• Framework assessment
• Prototype framework development pathway

Project Plan
![Page 7: Development of a Prototype Framework to Facilitate Interoperable Freshwater Modelling in New Zealand Daniel Rutledge, Sandy Elliott, Val Snow, Gabi Turek,](https://reader036.fdocuments.us/reader036/viewer/2022083006/56649f355503460f94c53abd/html5/thumbnails/7.jpg)
User Workshop Summary• Framework Criteria
– Open (including open source)– Scientifically credible– Easy to add new models and databases– Auditable– Identify uncertainty, assumptions made, and confidence bounds– Collaborative governance structure
• Expected Benefits– Efficiency– More robust model estimates– Transparency– Better and more timely policy and regulatory decisions– Decreased costs of model provisioning– Answer more complex questions

Stage 1 – Preliminary Screening
• Several existing reviews available*
• Consistent, unified method to categorise and characterise available frameworks is lacking
• Developed screening criteria based on peer-reviewed literature, web searches, discussions with framework developers, personal knowledge, results from workshop
*Argent 2004, Hutchings et al. 2002, Jagers 2010

Stage 1 Screening Results• 18 frameworks screened
• 12 frameworks not selected for full review
• Reasons for rejection– Aspatial– Uncertainty over longevity or no activity– Not flexible or adaptable– Targeted at another domain– Proprietary
• 6 selected for full review– CSDMS, OMS3, OpenMI, OpenPalm, TIME, Pegasus

Stage 2 – Full Review
• Developed 32 assessment criteria based on workshop criteria and findings from the screening
• Ranked the criteria (Key, High, Medium)
• Final selection based largely on 13 Key Criteria

Stage 2 – Full Review Results• All frameworks have many benefits and some limitations
• CSDMS and OpenPalm: mainly for highly complex modelling on high-performance computers
• TIME: high risk due to concerns over longevity and lack of investment by main funding organisation (CSIRO)
• Pegasus: Good for large workflowss, but not necessarily interactive modelling
• Conclusions– Proceed with further testing of OMS3– Hold OpenMI in reserve (issues with new version 2.0)

OMS3 Overview & Testing• OMS = Open Modelling System
• Developers: USDA NRCS, Colorado State, USGS
• Attributes– Java-Based (Console for Model Development & Coupling)– Metadata Standards– Model components made discoverable via annotation
(vs. wrapping in OpenMI)– Weak on data integration (does not follow open standards)
• Testing– Models: APSIM, Overseer, WATYIELD, Irrigation– Data: ClimDB (NIWA), SoilsDB (Landcare Research) via Web Services

Next Steps
• Complete OMS3 testing (Feb 2013)
• Project Workshop (June 2013)
• Final Report & Implementation Plan(End September 2013)
