HW#6 - Elevation Data Interpolation

Note: You may work in pairs on this assignment.

The objective of this assignment is to interpolate a set of MODFLOW layer elevations using the scatter point tools in GMS. We will start with an existing MODFLOW model:

Do the following:

1) Download and unzip the following project:

interpcase.zip

2) Open the project within GMS. This is a partially completed one layer MODFLOW model of a site. However, we need to interpolate the top and bottom elevations and a set of starting heads.

3) Note that there are two text files in the folder with scatter point data:

elevs_bottom.txt
elevs_top.txt

Open the files in text editor to review the contents. One contains a series of elevations for the top of the aquifer and the other contains a series of elevations for the bottom of the aquifer.

4) Use the File|Open command to import each of the two text files as 2D Scatter Point sets.

3) Use the elevs_top scatter point set to interpolate to the MODFLOW top elevation array.

4) Use the elevs_bottom scatter point set to interpolate to the MODFLOW bottom elevation array.

6) Redo the interpolation while experimenting with 2-3 of the other interpolation options. Save the interpolated arrays that you are the most comfortable with.
