  1. LIFE02/ENV/P/000416 Geographical Information System&Modelling

  2. Presentation Overview • GIS and database • Modelling • MOHID modelling system • Case study: Trancão basin • Progress • Future work

  3. Geographical Information System • Field data: • Storage • Treatment • Analysis • Georeferenciation • Web sharing

  4. Project GIS allows to… • Systematize experimental data • Share results on the Internet • Search and query information • Model results visualisation and comparison with field data http://www.mohid.com/GIS/ecoriver

  5. MOHID Modelling System LAND (basins, aquifers) River Network Surface Water (ocean, estuaries, reservoirs) GIS (basin, bathymetry creator) GUI (Graphical User Interface)

  6. MOHID Applications

  7. MOHID Applications Trancão

  8. MOHID Applications Trancão

  9. User Interface – MOHID GIS • Generation of • Curvilinear Grids • Digital Terrain Models • Bathymetries • Delineation of Basins • Generation of Drainage Network • Overlay of thematic maps • 4D Visualization • 3D (X, Y, Z) • Time (t) • Build using .NET Languages, OpenGL, Open GIS and HDF Digital Terrain Creator Basin Delineator Convert To HDF 5

  10. User Interface – MOHID GIS Ex: Generating an Input matrix based on Land Use

  11. Transport of a Generic Conservative Property • No infiltration • Constant precipitation = 1 mm/day • Initial concentration = 1 kg/m3 Code Ready for Sediment and Toxicity simulations! • Couple with Module Water Quality • Coding Toxicity Sinks & Sources

  12. Ongoing Developments - Integration Coupling hydrodynamic models and biogeochemical models (0D) approach Light Phytoplankton Zooplankton Organic matter Nutrients Temperature Bacteria

  13. Ongoing Developments – Coupling Water Quality Models • Pelagic water quality/ecological module based on EPA model WASP • 15 compartments: phytoplankton, zooplankton, nitrate, nitrite, ammonia, inorg. phosphorus, PON, DON labile, DON refractory, POP, DOP labile, DOP refractory, oxygen, bacteria, ciliates • Several robust applications in estuaries, coastal zones and reservoirs

  14. Ongoing Developments – Coupling Water Quality Models • Recently adapted pelagic and benthic module from CEQUALW2 (3.1) (http://www.cee.pdx.edu/w2/) • Variable number of compartments: algae groups, epiphyton/periphyton groups, nitrate, ammonia, inorg. phosphorus, DOM labile, DOM refractory, POM labile, POM refractory, particulate silica, dissolved silica, inorg. carbon, pH, oxygen, HCO3, CO3 • Two decades of applications in reservoirs, lakes and estuarine systems

  15. Ongoing Developments – Coupling Water Quality Models • WaterQuality • Pelagic water quality module based on EPA model WASP • CEQUALW2 • Adapted pelagic and benthic module from CEQUALW2 (3.1) • Life • Pelagic multi-parameter ecological model with microbial loop and variable stoichiometry • SedimentQuality • Carbon-Nitrogen unsaturated biogeochemical cycle model withmicrobial loop and variable stoichiometry based on RZWQM/OMNI

  16. Conclusions/Future Work • Database and GIS are up to date but needs improvements • MOHID GIS constructs input data and allows visualization of results • MOHID Land solves hydrodynamics and a “generic” property transport • Future Work • Finish Development of MOHID Land • Couple MOHID Water and MOHID Land using MPI • Model Calibration with project results
