2 Presentation Overview 1.GIS and database 2.Modelling i.MOHID modelling system ii.Case study: Trancão basin a)Progress b)Future work

3 Geographical Information System  Field data: Storage Storage Treatment Treatment Analysis 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

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

6 MOHID Applications

8 MOHID Applications Trancão

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

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

11 Case Study: Trancão Basin No infiltration No infiltration Constant precipitation = 1 mm/day Constant precipitation = 1 mm/day RunOff

12 Channel Flow No infiltration No infiltration Constant precipitation = 1 mm/day Constant precipitation = 1 mm/day Caudal [m3/s]

13 Channel Flow With infiltration With infiltration Constant precipitation = 1 mm/day Constant precipitation = 1 mm/day Caudal [m3/s]

14 Channel Flow and Soil Water Content With infiltration With infiltration Constant precipitation = 1 mm/day Constant precipitation = 1 mm/day

15 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

16 Transport of a Generic Conservative Property   Discharge of 0.1 m3/s during 2h   Initial Concentration – 1kg/m3 Code Ready for Sediment and Toxicity simulations! Couple with Module Water Quality Coding Toxicity Sinks & Sources

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

18 Transport Deposition /Erosion Processes Light Extinction Suspended Matter PhytoplanktonNutrients ZooplanktonBacteria Precipitation Lateral Discharges Hydrodynamics Toxicity Ecotoxicity Sediment Load Settling velocity Salinity

19  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 Ongoing Developments – Coupling Water Quality Models

20  Recently adapted pelagic and benthic module from CEQUALW2 (3.1) (http://www.cee.pdx.edu/w2/)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, HCO 3, CO 3  Two decades of applications in reservoirs, lakes and estuarine systems Ongoing Developments – Coupling Water Quality Models

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

22 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 Finish Development of MOHID Land Couple MOHID Water and MOHID Land using MPI Couple MOHID Water and MOHID Land using MPI Model Calibration with project results Model Calibration with project results
