Presentation Transcript

  1. WG 3 - Model application • c. 15 members • What are good examples of model application to applied problems? • Planning • Interaction with customers and end-users • Modelling • Interpretation of results • Implementation

  2. State-of-the-art report • Started with 36 case studies, reduced to 28 • End-user survey • Informal contacts • Participation in meetings • Results from case studies • Special topics • Decision support systems • “Shared vision modelling” • Scaling (generic to all WGs) • Uncertainty (generic to all WGs) • Validation (with WG2)

  3. End-user survey • E.g. • Public bodies resource and river management • Companies – water, hydro • Consortia – committees, public, private, NGO • Don’t forget the local people • The issue of scale • Species or community • Models too specialist • Modellers don’t give “the answer”

  4. UK (2) USA (2) Finland (2) Norway (4) Spain (1) Austria (1) Switzerland (2) France (2) Belgium (1) Slovenia (1) Canada (3) Netherlands (1) Denmark (1) Germany (3) Case-studies

  5. Case studies • A valuable resource • How models were applied • Three categories • ”natural morphology rivers”, keep it simple, collect and use data • Simple models used in minimum flow studies • More complex situations: resource allocation, trade-offs, flow regulation on engineered channels

  6. Case Studies – good examples • Agreement • Consultation, participation • Use of instrumentation to collect data rapidly • Moving towards: • multi-variate • multi-reach, broader scales • Reality check • Recommendations applied (+ elsewhere) • Alternatives suggested, refined and discussed interactively

  7. Case studies – not so good • Managers asking questions that modellers cannot answer • Models at too small scale – upscaling non-existant or uncertain • Modellers unclear as to WHO END-USERS ARE • Role of experts unclear

  8. Future work • Many WG3 members interested in the issue of scale • what is an appropriate scale? • should we be up-scaling (and how?) • how can data from different scaled be integrated

  9. Future work • Progress • Meeting on scaling in December 2002 • Collaborative project(s) • Validation of habitat classifications using detailed hydraulic data • use of large-scale river models • review paper – scaling concepts from hydrology and ecology • more please!
