Catalog Description: Groundwater Modeling - Advanced study of the mathematics of

groundwater flow and the formulation of analytical and numerical models that describe steady-state and transient groundwater flow systems. This will involve the use of physical models, flownets, spreadsheets, analytical solutions, and finite-difference and finite-element models.



* Obtain a basic understanding of groundwater modeling principles.

* Learn how to evaluate boundary conditions.

* Learn how to interpret modeling results.


Topics to be covered:

1. Overview of groundwater modeling; conceptual and analytical models

2. Research and trends in groundwater modeling; prediction validity

3. Numerical models; limitations and sources of errors

4. Interpret field data and develop a practical site hydrogeologic conceptualization model

5. Finite Difference Methods

6. Finite Element Methods

7. Matrix solution techniques

8. Design of grids, boundary conditions, and sensitivity analysis

9. Import topographic data and borehole lithology to create the model grid*

10. Applications in Groundwater Flow

11.-- 15. MODFLOW

a. Assign grid-independent stream segments for surface water/groundwater interactions

b. Import distributed model properties for discrete data points and field measurements using the interpolation methods (i.e. Kriging, Natural Neighbor, or Inverse Distance)

c. Discretize and optimize the model grid

d. Calibrate the model using manual and automated techniques

e. Evaluate remediation alternatives using the calibrated model

f. Delineate capture zones using forward and reverse particle tracking

g. Interpret and display the modeling results in 2-D and 3-D.

12. WinPest and MT3D/RT3D and Zone Budget calculations
