I am working on ArcSWAT and finding difficulties in inputting data for SWAT.
Like I have three types of soil: red sandy, red gravelly and older alluvial Soil in my area of alwer rajasthan but I am not able to give this data as input.
you might contact Raghavan Srinivasan (Texas A & M University), Balaji Narasimhan (Indian Institute of Technology-Madras) or A.K. Gosain (Indian Institute of Technology, Delhi).
You can find all the soil properties that required by SWAT for all the soils in world in the attached file which download from http://www.swatcupiran.com/, and then you can directly put the soil data in the usersoil table in swat database.
