Seminar Flyer:

Many experiments, field studies, and simulations are limited by the number of physical measurement points that can be contained within the study or used for comparison to a model. Even in highly instrumented experiments or field sites, a relatively small number of data points are available. Transparent soil, where the indices of refraction of the soil grains and the pore fluid are matched, overcomes this limitation in hydraulic, thermal, and mechanical experiments of geo-materials. Using digital cameras to capture transparent soil experiments allows for spatial resolution down to the millimeter scale of moisture content, temperature, and/or displacement across experimental domains. This highly visual presentation will describe development of transparent soil and display the high temporal and spatial resolution capabilities in multi-phase flow, carbon dioxide storage, and heat transport experiments.
