Title(s):Main Title: Imaging of soil hydraulic conductivity patterns using EIT
Description(s):Abstract: Flow and transport processes in soils are governed by their hydraulic properties. Conventional methods for measuring soil hydraulic properties, especially in the field are invasive and typically have a poor spatial resolution. Recent results of low-frequency electrical impedance spectroscopy (EIS) measurements on a range of saturated and unsaturated soil samples indicate that spectral electrical properties can be related to hydraulic conductivity. Therefore, electrical impedance tomography (EIT) is a promising non-invasive measurement technique to determine hydraulic conductivity patterns in partially saturated soils and aquifers. In this project, we aim to establish EIT as a method to determine spatial patterns in hydraulic conductivity and to validate the hydraulic property patterns derived from EIT measurements in the laboratory and the field. This report first gives a short overview of the underlying theoretical principles and recent studies on this topic. Next, the proposed methodology is discussed and first test measurements on similar setups to test the proposed methodology are shown.
