Hi Jochen ,

thanks for your reply. i have seen the link you have sent as per the soil map their is one classification given for my area of interest. my question is can we successfully do HRU Analysis with only one soil classification?

Soils data can be difficult in some areas. There is a global dataset that is derived from FAO harmonised version. You can try using it wit SWAT.

http://www.waterbase.org/

you can take it from soil survey department or can use gis soil input data.

the data is not available with soil survey department. in FAO HWSD only one soil group is classified for the entire catchment. would it be enough for SWAT Model?

You can download also the information from SWAT web page in SWAT format.
