Daily Objectives #16 (March

Dr. Sanders
v Estimate how much water will
drain from a saturated porous medium. (We will test the estimates
by seeing how much drains from the Darcy tube!)
v Inject droplets of dye into the ground water flow model.
v
State Darcy's Law and explain
each of the variables in the formula.
v Using the map of ground water levels in southeast Wisconsin that you made last time (see p. 110), assuming the aquifer is 50 ft thick, and assuming a hydraulic conductivity (K) value of about 3 ft/day, estimate the ground water flow into Lake Michigan in T5N, R22E. Then, do the same for T7N, R22E--but be careful, as this one's trickier!
v Using Darcy's Law, evaulate and
interpret results
from the Darcy tube experiment.
v Explain what the following types
of flow system boundaries are:
> no-flow boundary
(also called an impermeable boundary),
> water table boundary, and
>
constant head boundary.
v Sketch the pathways of the dye as
it moves through the flow model, and on your drawing, identify the
following components of a flow net: flow lines, boundaries,
water table. (Show only the approximate position of
the water table; we will work on finding exact position next week).
