Request to verify the BD parameter unit in the soil file

[8064...@qq.com]

Hi all ，

The unit of BD parameter is t/m3 in APEX Theory Manual, but the range is 0.5-2.5. The manual also specifies the range, that is, "Bulk density values should fall between 1.1 and 1.9 Mg/m3". However, the unit of BD in SWAT's theoretical manual is mg/m3, and the range is 1.1 to 1,9mg/m3. Is this a little unreasonable, or is APEX's calculation of BD parameters different?

You misunderstood the SWAT manual. Mg/m3 is megagram per cubic meter, or ton per cubic meter, the same as APEX.
