By the
end of today's class, you should be able to do the following:
Hydraulic Properties of Rocks and
Sediment
v
Define and describe how one can measure
the following properties:
intrinsic
permeability (Ki )
hydraulic conductivity (K)
v
Explain the relationship between
permeability and hydraulic conductivity.
v
Tell in what units of measurement
each of these properties is expressed.
v Give typical ranges of each of
these hydraulic properties for various types of sediments, and explain any
trends in the ranges.
v Define the
terms
aquifer and
aquitard.
What makes water flow?
w Explain the term
hydraulic head, and tell how total hydraulic head relates to elevation
head and pressure head.
w For the ground water
model set-up that we created last week, sketch a topographic map of the area. Set your pencil at any point on the map and draw an arrow
showing the direction a marble or bowling ball would roll if it were set on the ground at
that point.
w For the same ground
water model set-up, sketch a water table map of the area. Your map
should have contours showing equal elevation of the water table. Set your pencil at any point on the map and draw an arrow showing the
direction of water flow in that area. What is the relationship between
water table and total hydraulic head?
w For the same ground
water model set-up, sketch a cross section with contours
illustrating the total hydraulic head. Set your pencil anywhere on the
cross section and draw arrows showing the direction of flow through the sand.
w For "Analysis B" at
the end of Chapter 3, draw water table contours using a 50-ft contour interval.
