  1. Lake EcosystemModellingWorking Group Summary of Progress since GLEON 12 – Israel, 4-8 April 2011

  2. Lake Ecosystem Modeling Working Group Total Participants > 40

  3. Lake Ecosystem Modelling Working GroupTimeline • Develop Mission Statement • Provide Model Overview • Determine Data Requirements of Models • Develop Core-Group (and Network) Model • Distribute GLEONites Model Profile Questionnaire • Generate Common Model Dataset(s) • Introduce New Model Framework • Take-Off • Conduct Interactive Workshops for Developers and Users • GLEON 10Torres, BrazilMay 2010 • GLEON 11Nanjing, China • October 2010 • GLEON 12 • Ramot, Israel • April 2011 • GLEON 13 • Lake Sunapee, NH • October 2011 • Start Multi-Model Comparisons (Lake Kinneret and Possibly Lake Rotoehu) - Temporal Scale: Hourly vs. Daily input • Spatial Scale: 1D vs. 3D • Conceptual Models (Check Possibility of Using PROTECH, PCLake, DYRESM-CAEDYM, CE-QUAL-W2 for Same lake – e.g., Lake Rotoehu) Action Items • Outline Generic Parameter Database in Google Spreadsheet to define model content and vocabulary

  8. Status of Open Source Model Library:FABM Coupled Physical Models Model Dimension / Grid Stratification & Vertical Mixing Comments MATLAB / CSV 0D N/A Generic FABM driver -Under development GLM General Lake Model 1D Lagrangian layered grid Ice cover Currently daily time-step only Simple to use GOTM General OceanTurbulence Model 1D Fixed grid Multiple turbulence models in library Assumes hypothetical column, so not good for small-medium lakes GETM General Estuarine Transport Model 2D/3D Regular or curvilinear in horizontal and sigma in vertical Uses GOTM turbulence library Open source, but complex to use TUFLOW-FV Flood and Coastal Simulation 2D/3D Flexible mesh in horizontal, and z-coordinate in vertical Uses GOTM turbulence library Not open-source

  9. GLM-FABM (alpha-version) Output (Using Matlab GUI by UWA) Link to AEMON site For parameter database entries go to
