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)

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
