Abstract

A pilot plant of artificial groundwater recharge on a test site of a former sewage farm was installed to control the process of migration of nutrients, heavy metals and organic compounds from the soil into the near surface groundwater and the surface waters. The study of the irrigation is intended to show, whether and at which quantity contaminants are remobilized by artificial recharge. To obtain a giudeline for decision-making both irrigation and non-irrigation alternatives are treated by a numerical model. Steady-state flow model is combined with a partical trecking post-processor and a trancient transport model (using FAST codes). Traveltimes of
