By
the end of today's class, you
should be able to do the following:
v Hydrostratigraphy
- Distinguish
between confined
aquifers and unconfined aquifers.
- Recognize
and delineate hydrostratigraphic
units.
- Explain
the difference between lithostratigraphic units
and hydrostratigraphic units.
v Flow Nets
- Identify boundaries
to a flow system, and for the first three listed below, tell the
relationship between the boundary and flow lines, and the boundary and
equipotential lines:
- no-flow
(impermeable) boundaries:
- hydrostratigraphic
- hydrodynamic
- water
table boundary
- constant
head
boundaries
- constant flow
boundaries (rarely used in modeling
natural systems).
v Hydrogeologic
Maps and Cross Sections
- Use
water levels in wells and/or piezometers, and flow system boundaries,
as the basis for drawing water level maps and flow nets.
- Use
Darcy's Law to calculate flow through an area illustrated on a flow net.
- Find
borehole data for Illinois, and use it to delineate hydrostratigraphic
units and construct hydrogeologic cross sections.
