Watertech Booth Slide 2013

  1. 1. 1
  2. 2. 2 SiteFX Environmental Data Management System
  3. 3. 3 Sitefx GW Database ► Database Management system with:  Data entry, sample tracking, and scheduling  Sample program design and reconciliation  Data standardization (analytical chemical names and units)  Data validation (including range checking) and data criteria screening  Reporting and advanced time-series graphing  Parametric and non-parametric statistics and trend analysis
  4. 4. 4 VIEWLOG Hydrogeologic Modelling System
  5. 5. 5 VIEWLOG Borehole GIS ► VIEWLOG provides integrated data management, visualization, analysis and modelling tools  GIS, with intelligent, geo-science data objects  Not just display, but meaningful data interaction  Scalable interpretation tools, from a single fracture to an entire watershed  Open, flexible, database design, with dynamic interaction with any table or query ► Over 700 users worldwide Well Name: 34C Elevation: 192.939 Metres Stratigraph 190 180 Overburden Eramosa
  6. 6. 6 VIEWLOG WebServer ► VIEWLOG Webserver provides data access for a wide range of users  Emphasis on ease of use ► On-line functions include:  Interactive mapping  Color contouring  Borehole logs  2-point cross sections  Basic query select functions  Time-series graphing US Geologic Survey Web Site built using VIEWLOG/Webserver
  7. 7. 7 VL-GSFLOW Integrated GW/SW Modelling System
  8. 8. 8 VL-GSFLOW ► GSFLOW: an open-source, fully-integrated Surface Water and Groundwater Modelling system  Surface Water model based on PRMS  Groundwater model based on MODFLOW-NWT ► Key VIEWLOG functions include:  Pre- and Port Processor for creating GSFLOW input files and reading GSFLOW outputs  Time series analysis tools  Gridded data animation tools
  9. 9. 9 GSFLOW is a combination of two USGS codes: MODFLOW-NWT and PRMS PRMS handles climate and soil water processes MODFLOW simulates GW flow, unsaturated flow (UZF), streamflow and lakes (SFR2/LAK3) GSFLOW Processes
  10. 10. 10 VL-GSFLOW Total Flow Routing ► GSFLOW simulates total flow in the streams, including runoff and baseflow discharge
  11. 11. 11 VL-GSFLOW Water Level Animations ► VL-GSFLOW provides full animation and hydrograph analysis tools
  12. 12. 12 VL-GSFLOW Overland Flow ► GSFLOW simulates both overland flow and interflow
  13. 13. 13 Soil Zone Storage and Cascade ► GSFLOW can simulate the storage and 3D movement of soil zone water using a cascading inter-cell network Till uplands Flow accumulates in swales
  14. 14. 14 Storage and 3D movement of water in the Soil Zone ► Soil zone moisture content Beach Deposits Till Upland - Till uplands drain both vertically and downslope - Lateral drainage to the beach deposits from the till uplands enhances recharge - Soil zone storage helps supply rate limited GW recharge to the lower layers
  15. 15. 15 Soil Zone Drainage (GW Recharge) ► When moisture is available (winter months) there is a near constant, but rate limited, drainage from the soil zone Beach DepositsTill Upland
  16. 16. 16 VL-GSFLOW GW Recharge ► GSFLOW provides ground water recharge estimates on a daily basis
  17. 17. 17 GW Discharge to the Soil Zone (Daily) Daily GW discharge to soil zone
  18. 18. 18 Time-varying GW Feedback ► The “contributing area” that generates true runoff depends on the time-varying position of the water table ► Example: Dunnian process response area varies seasonally between 5 and 25% of the study area ► Runoff occurs, but it is a groundwater dependent process!
  19. 19. 19 Water Table Fluctuation across Layers ► Water Table rises and falls through multiple thin, variably saturated, layers  Highly variable response to precipitation events ► GSFLOW NWT Solver – no dry cell problems! Water Table GW Discharge
  20. 20. 20 MODFLOW-NWT stable even when modelling steep gradients Shows daily, seasonal, and year-to-year response in heads Limestone Creek Milton Outlier
  21. 21. 21 Simulated Stage in Reservoirs OBSERVED PREDICTED Kelso Lake Hilton Falls
  22. 22. 22 Simulated Heads in Wells OBSERVED PREDICTED PGMN Well W00008 Quarry Well BH-112 Mohawk Raceway Well – Opsteen Farm
  23. 23. 23 Simulated Heads in Wellfield Monitors OBSERVED PREDICTED Campbellville – MW2/05B Kelso TW3/67 Kelso TW4/67 Kelso wells out of phase with normal seasonal response. Shows influence of high leakage from lake at summer stage
  24. 24. 24 Wellfield response to Reservoir levels Limestone Creek Milton Outlier
