Error migrating from ArcSWAT to QSWAT

[Maukthik Srivathsan J]

Hello,

I recently tried migrating an old swat model from arcswat to qswat through the swat editor runConvertFromArc command, but the command prompt displays "Cannot find QGIS 3.16 at C:\Program Files (x86)\QGIS 3.16.  Hit Enter to exit".

I have QGIS 3.18.3-Zürich (32 Bit), QSWAT3 1.6.0, SWAT editor 2012 10.12.30

Thank you in advance.

You need to do a bit of editing to runConvertFromArc.bat, which you will
find in C:\SWAT\SWATEditor, to match your QGIS installation.

1. Assuming your QGIS is in Program Files (x86), since you say it is 32
bit, just change 3.16 in line 2 of runConvertFromArc.bat to 3.18 (You
could also change line 5 in the same way, but it is not essential.)

2. Look in C:\Program Files (x86)\QGIS 3.18.3\bin to see if you have
qt5_env.bat and py3_env.bat. I suspect you will not have them. (They
were removed for some version of QGIS but I don't remember when.) If
you don't have them insert rem plus a space at the beginning of lines 10
and 11 to comment out the calls of these scripts.

It should then run OK.
If you get problems change the first line from @echo off to @echo on and
send me the output when you try to run it.

I realised afterwards there are a couple of things I omitted from my
last message:

1. Your QGIS directory in line2 probably should be C:\Program Files
(x86)\QGIS 3.18.3: I forgot the final .3

2. QGIS 3.18 is not a long term release, I think. So the setting of
QGISNAME on line 13 should be changed to

QGISNAME=qgis
