¹ The Ksat values termed “average” for the modeling analysis represent the mean K_sat values for each soil texture based on a national database of over 1,000 observed saturated hydraulic conductivities (Rawls, 1998).
²The Ksat values termed “compacted” and “loosened” for the modeling analysis represent the geometric mean Ksat values for soils within the national database developed by Rawls that have bulk densities higher and lower than the NRCS recommended value for the given soil texture class, respectively (Rawls, 1998).
