This collection of problems I encountered when running Arcswat is all my blood and tears on the way to running the model! ! !
It is recommended that you use ArcGIS 10.2 version. I run 10.7 and 10.2 at the same time. 10.2 successfully writes to the database, and 10.7 is stuck.
1. Problems related to writing soil data and weather generator, as shown in the figure:
Solution: It is recommended that you use Edit SWAT Inout - Databases to edit, and add soil properties and weather generator related data one by one, so that the above problems will not occur when writing.
If you find this troublesome, you can try another method. First create an access database to import the soil database and weather generator data, then copy the data from the newly created database and paste it into the SWAT2012 database under the SWAT model installation path. This is what I do. It can be run successfully. Just be careful to keep the data to 2 decimal places to avoid other problems later.
2. forrt1:error(65): floating invalid
The problem is that the soil database and weather generator data do not retain two decimal places (preferably two decimal places). When I modified it, I modified it directly in the SWAT2012 database under the swat installation path, and the operation was successful.
There are really too many strange problems with SWAT, many of which are database problems. I wish everyone a successful SWAT run! Good research!
