Daily Objectives #19 (March 31, 2009)                                        Dr. Sanders

By the end of today's class, you should be able to do the following: 

Ground Water Modeling: Basic Concepts and Analytical Model

    Some practical tasks:

Describe the steps in constructing a model, as given on pages 526-527 of the Fetter textbook.
  Calculate flow through a segment of aquifer using a flow net and Darcy's Law.
Calculate flow through a cube of aquifer as represented by a cardboard cube.

    Summing up:

        Explain the difference between a conceptual model, an analytical model, and a numerical model.
        Explain the purpose of a numerical model grid.
Explain how Darcy's law is used in a numerical model.

Ground Water Modeling: Conceptual Models

    Review: Describe the hydrostratigraphy of the modeled area.
Review: Describe the boundaries of the modeled area.
    New this time: Describe the stresses on the aquifer in the modeled area (recharge, evapotranspiration, pumping)
     New this time: Describe the initial conditions within the modeled area (where should the model begin its calculations?).
    Pete found these excellent resources for our study area:

            "Co-op 10" of the ISWS             USGS document     Regional planning document
Ground Water Modeling: Practice

     Work through all the steps described in the First Steps and  Building Your Model  documents (from a few weeks ago).  Today might be the day you get your model to run!
