NOTE: This exam is divided into** 6 **pages. At the bottom of each page is a button that submits your answers for the current page. You must use this button to enter your scores to the database. Clicking on the forward and back buttons of your browser or using one of the links shown above does NOT submit your answers.

At the end of this exam you will encounter a confirmation page that lets you either finish the exam or go back to page 1 so that you can cycle through all of the pages again and review your answers.You can loop through the pages as many times as you want as long as you finish the exam on time.

If you accidentally kill your browser, simply bring up a new one and log on to the test again. Your previously submitted answers will be retained.

1. (1 pt each) True or False:

a. T F (concmod) Most aquifer systems are

transientby nature.b. T F (gw-concepts)

Parsimonyis defined as always using the most sophisticated and comprehensive model that your time and budget allow.c. T F (modflow) A

time stepin a transient MODFLOW simulation can consist of either one stress period or many stress periods, depending on how much the corresponding model stress varies with time.d. T F (bc) A ground water divide is a type of

no-flowboundary condition.e. T F (goveq)

Specific storageis a function of both the soil stiffness and the compressibility of water.f. T F (gms) The midpoints of arcs are called

nodesand the endpoints are calledvertices.g. T F (transient) In general, the smaller the

cell size, the smaller thetime step sizein order to achieve sufficient accuracy for a transient simulation.h. T F (calibration) In general, the number of parameters should be

greater thanthe number of observations when performing model calibration.i. T F (calibration) The Mean Absolute Error is generally

smallerthan the Mean Error.j. T F (head-darcy) Water will always flow from a point of high

highpressure to a zone oflowpressure.
