NOTE: This exam is divided into** 7 **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 (seep-goveq) A direct solution to the governing differential equation in the form of an equation or formula is called an

analyticalsolution.b. T F (seep-analytical) A

flow netconsists of flow lines and pressure head contours.c. T F (seep-flownets) When considering flow nets for unconfined problems, the

line of seepage(phreatic surface) corresponds to a flow lined. T F (seep-flownets) For

anisotropicsoils, the flow lines and equipotential lines will not necessarily intersect at right angles.e. T F (seep-head, darcy) Water cannot flow from a region of

lowpressure to a region ofhighpressure.f. T F (seep-welleq) The standard well equation for

confinedaquifers assumes that the flow is completely horizontal.g. T F (seep-finelem) The

exit faceboundary condition forces the pore pressure to be zero at all points along the exit face, assuming the points are below the exit point of the phreatic surface.h. T F (seep-finelem) Both the finite element and finite different methods result in a matrix of equations that is

banded and symmetric.i. T F (seep-head, darcy)

Pressure headat a point is the height that the water would rise in a standpipe inserted at the point, measured relative to the selected datum.j. T F (seep-head, darcy) When flowing

perpendicularto the layers, the layer with the lowest k value has the largest impact on the flowrate through the system of layers.k. T F (seep-finelem) If you don't explicitly assign a boundary condition in SEEP2D, it is assumed to be a

constant headboundary by default.l. T F (seep-flownets) For a flow net involving a

sheetpile, the boundary corresponding to the sheetpile (down one side and up the other) represents an equipotential line.m. T F (seep-welleq) When deriving the equations for flow to a well in a

confinedaquifer, the Dupuit assumptions are not needed.n. T F (seep-goveq) For a confined aquifer,

transmissivityis defined as the hydraulic conductivity divided by the thickness.o. T F (seep-head, darcy) The

radius of influence (R)for a well is defined as the radius at which drawdown due to pumping at the well is negligible.
