*where D is bulk density, C - % of clay, S - % of silt, OC - organic content, CEC - cation exchange capacity, pH - soil pH, and T is the topsoil and subsoil distinction. FAO_2008 (link) defines topsoil as 0-30 cm layer and subsoil as 30-100 cm layer. When soil depth is within the definition of topsoil then T = 1, otherwise T = 0.

**K saturated results for Toth equation are in cm/day, the LISFLOOD model requires mm/day.
