    Notes on slide 1

    This video looks at an area in the context of the recharge and the stratigraphic model. The roadways come on to give you locational context. We’ve randomly selected a roadway in the center of the region. The recharge map and the stratigraphic model are clipped to the roadway. Now we’re rotating the model so you can see below ground. The recharge map floats above the model on a flat plane. The green space below it is really air – the very bottom of the green layer is the ground surface. The aquifers and other materials are evident in the layers below.If you wanted to analyze the potential for contamination of the shallow aquifers from any land use or event (accident), you could do that from the model.

    4. BACOG Water Resources Initiative
      Barrington Area Council of Governments
      Factors:
      • Total reliance on groundwater
      • Growth & increasing water consumption
      • Lack of infrastructure & alternate supply
      • Contamination risks
      • Sensitive natural areas
    5. BACOG Water Resources Initiative
      Barrington Area Council of Governments
      Basic Questions:
      • Where Is the Water?
      • How Much Water Is There?
      • Is the Supply Sustainable?
      • What is the Water Quality?
    6. The BACOG Approach
      DATA
      The BACOG model incorporates over 25,000 wells with more than 110,000 lines of soil descriptions.
    7. The BACOG Approach
      -7.5
      METHOD
      -8.5
      The BACOG approach processes all available data into hydraulic conductivity values based on soil descriptions.
      -2.5
      -5.42
      -6.33
      -4.78
      -5.83
      -7.5
    8. The BACOG Approach
      TW1-05
      • MAPPING & VISUALIZATION
      The hydraulic conductivities are interpolated for areas between data points and bedrock and surface topographies are incorporated.
    9. APPLICATIONS
      The BACOG Approach
      BACOG governments use the model for practical applications and environmental analysis.
