KEY to EXERCISE:

EXPLORING APPLICATION OF THE SOLUTION TO A SYSTEM FOR WHICH IT WAS NOT ORIGINALLY INTENDED

To represent the half space, simply set h2 equal to h1 and use the results from the left hand side. The symmetry will represent a divide in the middle of the land mass which is the same as a no-flow boundary.


All of the conditions can be solved
1. K = 1x10-4 m/day
2. K = 1x10-1 m/day
3. ET = 0.85 m/yr
4. W = 0 m/yr

Diagrams are shown below for each case. Visit the applet to explore the response of the system and get specific values of flow and head for each case.

Evaluate and check your results as you proceed.

1. for K = 1x10-4 m/day and all other parameters as in the base case except that h2 equals h1:









2. for K = 1x10-1 m/day and all other parameters as in the base case except that h2 equals h1:









3. for ET 1.85 m/yr, that is W = -0.05 = -1.37 x 10-4 m/day and all other parameters as in the base case except that h2 equals h1:







4. for W = 0 and all other parameters as in the base case except that h2 equals h1:








Do all of the results make physical sense to you?
