Dr. Sanders
By
the end of today's class, you should be able to do the
following:
v
Using someone else's sketch of
water levels in piezometers (I will assign this part), draw a
quantitatively accurate flow net, including flow lines, equipotential
lines (labeled with their hydraulic head value), and water table.
v
Dam Flow Net: Post your dam
flow net and compare it to those drawn by others in the class.
v Cross
Section of the Project Study Area: Reminder: Homework
Assignment #6, due on Thursday, is to draw a cross section for the
study area based on boring logs of the from the Illinois State
Geological Survey's digital database.
v Conceptual
Models:
r List and describe the three
components of a conceptual model: hydrostratigraphic units, boundaries,
and stresses.
r Based on the geologic cross
sections constructed by all of your group members, make a conceptual
model for your study area.
v Ground
Water Modeling Software: Download and install a copy of Graphic
Groundwater (GGW). You can find it linked to this course's home page.
First, download Version 3.47 and install it. Then download
Version 3.52; it is simply an update and not the full version, so
you'll need to install 3.47 before 3.52 will work. Open up the
sample model
Please note: Some of the GGW links work only in Internet Explorer, and
not in Netscape. The opposite may be true for some of the ESCI
337 course pages, which I compose in Netscape. As a general rule, if you are having
trouble with a link, try opening the page in a different browser.
You miay wish to examine the files below as a sample of a GGW
model. To get each file, double click on the link and select
"Save File", then save each file in a place where you can find it
again. If that doesn't work, then just right click on the link on
this page and select "Save Link Target As". Then save it to a
place where you can find it again.
