Table 2 shows calibrated rotavirus partition coefficients for bare and vegetated surface conditions for Alvin, Catlin and Darwin soils. It was observed that the parameters k12 and k21 were more sensitive compared to the parameter k23. The parameter k12 affected the peak of the rotavirus recovery curve while the parameter k21 dictated the shape of the curve. Parameter k23 governed the formation of pathogen and soil particle aggregate which was not quantified in this study. In the case of vegetated surface, parameters k12 and k14 were two sensitive parameters, which governed how many pathogens got attached to soil surface and vegetation, respectively. Parameters k21 and k41 were another set of sensitive parameters which governed how many pathogens got released from soil surface and vegetation, respectively.
