Open arc-swat (ARC-GIS). Go to Edit swat input.choose databases.

you will be asked select data bases to edit. you can select land cover/plant growth .you can add your study area  land-use data in to the databases and save them.then upload your lulc map and reclassify them.similar procedure  for soil map.

Or else ,when you upload lulc map,you will be known what are the different land use classes your study region has got. choose corresponding US codes and prepare lookup table. for example if your region has evergreen forests , the corresponding code for US region is FRSE. prepare lookup table with these codes. You  can get these from SWAT2012 file located in your project folder or you can get it in the arcswat folder(software).

The first method is always better.

You can go to Disk C --> Program files where you install SWAT model . All name of land-uses and codes were stored in the table ( format in Access file).
