Bad input on GWT test problem #74

Email from Richard Winston:

Hi. I've been working on more fully supporting MT3D-USGS in ModelMuse. As part of that, I'm trying to reproduce the "gwt" example in MT3D-USGS. However, it looks like the input for the SFT file doesn't match the input instructions. The problem is on lines 18 and 19 of gwt.sft where the boundary conditions are specified. I have copied them at the end of this message. It looks like what was intended was to have headwater boundaries in the first reaches of segments 1 and 3 but segment numbers are not part of the input for SFT so what actually is specified is a pair of precipitation boundaries with concentrations of zero.

I verified that this was in fact bad input. I'm guessing that this was left over from early development and when format changes were made prior to release, we never caught this issue in the test problem and that it escaped our attention until Richard noticed it.
