This article summarizes a study directed towards the prediction of oil spill migration in sandy soils. Such a prediction is needed for the design of remedial measures against soil and groundwater contamination. The geneai approach in this study is to convert available data concerning water infiltration into equivalent unknown data concerning oil spillage. This information is then fed into a numerical model by which the oil spill migration is simulated. Laboratory measurements including retention curve, hydraulic conductivity and infiltration rate, were made separately for water and kerosene in order to evaluate and confirm the suggested approach.
