Hello SWAT Users, I'm working on my master's thesis about the impact of climate change on water resources in the Azraq basin in Jordan. so now i reach the HRU Analysis and i need to make a lookup table for the soil data but i have a problem because my soil data didn't found in the SWAT2012 Database and i don't have all data about this basin so what can I do? When I made a lookup table, the error message box appeared: "The soil does not exist in the usersoils database. correct problem and try again," and "Some of the soil names in the soil lookup table do not occur in the soils database. This must be corrected before continuing." The soil types that I have are "Clay (Cl), Clay Loam (ClLo), Sandy Clay Loam (SaClLo), Loam (Lo), Silty Loam (SiLo), Sandy Loam (SaLo), Loamy Sand (LoSa), and Sand (Sa)." Please, I need help. Best regards
