Daily Objectives #11 (February 24, 2009)                                        Dr. Sanders

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.
