Description: This project aspires to study the transport and fate of organic contaminants in the vadose zone by addressing several important issues such as hysteresis effects, soil moisture content and soil properties. It further proposes to use experimental techniques at three different scales in order to investigate the interaction between contaminants and hydrologically/chemically heterogeneous porous media.

描述：该项目旨在研究交通和命运 通过解决几个重要问题来消除包气区的有机污染物 滞后效应、土壤湿度和土壤等问​​题 特性。它还建议在三个方面使用实验技术 为了研究不同尺度之间的相互作用 污染物和水文/化学非均质多孔介质。
