Dear all,
I am running SWAT model for a selected study area located in Sri Lanka.
Earlier I used the soil map available in FAO website (http://www.fao.org/geonetwork/srv/en/metadata.show?id=14116).  According to FAO map my  study area contain only one soil type. 
So using the Elevation (Digital Elevation Model), Land use and local classifications I produced the following soil map. Map is herewith attached. So i would like to know how can I use this map  for ArcSWAT?  Or do I need to improve this further? 
I am very much grateful for your kind responses.
Thank You.

I hope you had downloaded the HWSD Soils. In this map too, we see only a few solid for the entire country. I came to know that the Soilgrids.org site provides better maps compatible with ArcSWAT. I went to the site and downloaded a piece ( The site has download restrictions) but that raster does not show any table to proceed with. Also, I do not know how to find the related ArcSWAT Soil database and the Lookup Table. I have posted a question on this. 

Dealing with soils is not that easy in ArcSWAT. Many soil maps and data are there but one cannot find the corresponding ArcSWAT Parameters. This is the issue. I have seen some work where they have built that database from the beginning for some areas of foreign countries.
