Surfactants occur already in undisturbed biological processes in soils but within the development of remediation techniques these substances are of large interest because of their interaction with hydrophobic substances. The standard models for (un-)saturated water flow and solute transport are extended to include the influence of the surfactant transport on the flow of the water phase. Two effects of surfactants on (un-)saturated water flow are included: the modification of the interfacial tension between water and air and the swelling of clay minerals due to sorption of surfactants. Simulations are presented, which exhibit the feedback of surfactant transport on water flow and content. An identification algorithm for hydraulic soil properties has been developed that supplements the simulation tool.
