By the
end of today's class, you should be able to do the following:
Hydraulic Properties of Rocks and
Sediment
v Review: Define the
terms
aquifer and
aquitard.
v List rocks and
sediments that commonly are used as aquifers, and those that commonly form aquitards.
v Describe the
effect of fracturing on the hydraulic conductivity of a rock or sediment.
v Explain what is
meant by hydrostratigraphy, and tell how it differs from lithostratigraphy.
What makes water flow?
w Draw a water table map
for an area of low relief with a stream running (west to east) through the
center.
w Draw a water table map
for an area of low relief with an oval-shaped lake in the center.
w Using your water table
contour map from the end of Chapter 3 (which we worked on last time), draw flow
lines to indicate the direction of ground water flow throughout the area.
w State the rules of
contours with regard to their touching, crossing, or ending; explain how to
choose and use appropriate contour intervals; and tell how to determine where to stop
drawing contours near the edges of a map.
w List the three kinds
of lines that one draws when creating a flow net, and explain the
purpose/meaning of each kind of line.
w For each kind of line
in a flow net, tell how it relates to the other kinds of lines (e.g.
perpendicular, parallel, oblique).
