Previous researchers have not been able to predict the influence of crude oil soil contamination on either the mechanistic dimensional detachment parameter b0 or the threshold parameter b1 of mechanistic detachment model (Wilson model). The aims of this research were: 1) to investigate the influence of crude oil on deriving Wilson model parameters, b0 and b1, with two setups at different scales and different soil moisture contents; and 2) to predict b0 and b1 in crude oil contaminated dry soils with varying levels of contamination.
