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 (calibration) When computing a weighted error norm such as the sum of the squared weighted residuals, the

weightfor a particular observation is typically inversely proportional to the size of the calibration target (conf. interval).b. T F (modflow) You can improve the convergence of an oscillating MODFLOW model by reducing the

convergence tolerance.c. T F (gms) You can have multiple 2D scatter point sets in GMS, and each scatter point set can have multiple

data sets.d. T F (calibration) The

RMSerror norm is generally greater than theMAEerror norm.e. T F (gms) When interpolating MODFLOW grid layer elevations using the GMS interpolation tools, the

morepoints you have, thelessdifference it makes which interpolation scheme you use.f. T F (modflow) If a cell is going

dryin a MODFLOW model, it can often be rectified by either decreasing the recharge or increasing the K.g. T F (modflow) With a typical MODFLOW solver, increasing the

acceleration parameterwill make the model converge more rapidly but it may become unstable.h. T F (gms) You can have

multiplesets of overlapping polygons in a single coverage in a GMS conceptual model as long as each polygon only has one property.i. T F (calibration) You can choose

river conductanceas one of your parameters for automated calibration with PEST.j. T F (calibration)

PESTis an acronym derived from Parameter Evaluation Software Tool.
