Comparing Time-Domain Reflectometry and Electrical Resistivity Tomography on a Dike Model

A013 COMPARING TIME-DOMAIN REFLECTOMETRY AND ELECTRICAL RESISTIVITY TOMOGRAPHY ON A DIKE MODEL Introduction 1 To ensure the stability of earthen structures like flood protection dikes geophysical measurement methods can be applied. Here the geotechnical engineer is interested in knowing the quantitative water content and how it changes over time. This requires a monitoring system that is able to monitor and predict soil water content over large areas. To this end a combination of two measurement systems is tested. The next project phase will also include numerical simulation as a means of including meteorological factors into the monitoring system. In the
