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.
v
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
v
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!
