In the laboratory each group will:

a) Design an experiment to simulate a real world situation,
b) Perform the flow portion of the experiment,
c) Model the flow and transport portions of the experiment to make a prediction,
d) Perform the transport experiment,
e) Compare the prediction to the experimental results, and
f) Calibrate the model to make predictions and measurements match.

Lab session 3: final presentations (held in classroom)

Students present final modeling results that compare prior and post model predicitons versus measured data. This should include:

a) heterogeneous steady state model in Excel
b) pre-experiment model prediction
c) experimental results (dye traces, measured heads, measured inputs, measured discharge, boundary conditions)
d) comparison of experimental results to apriori prediction
e) modify model to better match measured results (called calibrating the model)
f) compare measured results to calibrated model (measured versus modeled heads, measured versus modeled fluxes, measured versus modeled dye traces)

Class Projects:

Student groups performed a series of experiments using equipment in the Hydraulics Laboratory. The measured
and modeled results are shown in the PowerPoint presentations. The groundwater models are in Excel format.

Flow around barrier to a well experiment and simulation
Plume capture experiment and simulation
Infiltration with flow to surface water
Flow to well showing plume migration experiment and simulation

Grades

Grading will consist of 3  exams (50%), laboratory experiments (25%), and individual projects (25%).

Tests will be part open book and part closed book. Open book tests allow for use of the textbood, and one page (1 side) of student notes. Closed book portions allow for one page of notes. The tests will cover class lectures, assigned homework, and assigned reading.  Some old tests are included as links on this web page.

Projects: Groundwater Spring 2015

 

Groups of 3 or 4 Students:   In the laboratory each group will:  a) Design an experiment to simulate a real world situation, b) Perform the flow portion of the experiment, c) Model the flow and transport portions of the experiment to make a prediction, d) Perform the transport experiment, e) Compare the prediction to the experimental results, and f) Calibrate the model to make predictions and measurements match.  Document this in a PowerPoint presentation with more detailed backup slides (i.e., some pages with smaller fonts intended to be read but skipped over in the presentation). Deadlines will be spread throughout the semester. The hydraulic conductivity of the sands in the Hydraulics Lab is around 0.75 to 0.25 cm/s.

 

Each Individual Student: Pick a watershed/ groundwater basin of his or her choice. Students should spend some time online to make sure information is available for the chosen watershed. Each student must have a different system. Local systems (Mesilla Bolson, Hueco Bolson, Gila River are OK).

Intermediate deadlines will occur throughout the semester and then everything assembled in a final report. 75% of any lost credit can be recovered in the final report if noted problems are fixed.

1. (10%) Fit the flow data from the main stream to a log-normal distribution. Make a probability curve to examine goodness of fit. (Optionally you can use another distribution) (show how to do this in Excel)
2. (10%) Describe the geology and aquifer system(s) in your watershed. Show any available piezometric surface maps. (2-3 pages)
3. (10%) Make a recharge and discharge budget for the groundwater in your watershed. What fraction of discharge does pumping represent? Is the groundwater being mined or are recharge and discharge in balance.
4. (10%) What are the water quality issues? Describe the water chemistry of the major aquifers in your system. What controls that chemistry? What are source of contaminants and salinity?
5. (10%) Estimate the average rate of precipitation and evapotranspiration for your watershed. Show graphs of how it varies annually over a period of > 10 years. (show students how to access online Utah State data)
6. (10%) Outline a plan for managing your watershed. This includes: aquifer water quality, aquifer recharge enhancement if needed, limitations on pumping, etc.
7. (40%) Explain your results in a PowerPoint presentation and 10-15-page paper. (most of paper is graphs and figures).

 

 

 

 

Policy on Cheating

Students are expected to be above reproach in all scholastic activities. Students who engage in scholastic dishonesty are subject to disciplinary penalties, including the possibility of failure in the course and dismissal from the university. "Scholastic dishonesty included but is not limited to cheating, plagiarism, collusion, the submission for credit of any work or materials that are attributable in whole or in part to another person, taking an examination for another person, any act designed to give unfair advantage to a student or the attempt to commit such acts." Regents' Rules and regulations, Part One, Chapter VI, Section 3, Subsection 3.2, Subdivision 3.22. Since, scholastic dishonesty harms the individual, all students, and the integrity of the university, policies on scholastic dishonesty will be strictly enforced. In short, cheating will not be tolerated.

Class Format

The class will generally consist of short lectures followed by problem solving sessions. Some of the problem solving sessions are intended to promote thought and discussion; others are to work through homework. It is expected that the student will have read the relevant chapter and worked all assigned homework prior to coming to class. A portion of the class will be online.
