# 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) Use the **tops.sp2** scatter point set to interpolate to the MODFLOW top elevation array.

4) Use the **bottoms2.sp2** scatter point set to interpolate to the MODFLOW bottom elevation array.

5) Use the *Data Calculator* to create a data set on the tops.sp2 scatter point set representing the top elevations **minus 10 feet**. Call your new data set shead. Interpolate this data set to the MODFLOW* Starting Heads* array.

6) Redo the interpolation while experimenting with each of the interpolation options. Save the interpolated arrays that you are the most comfortable with.

### Submittal Instructions

Save the GMS project with the completed solution. Zip up all files associated with the project.
