Title: Data from in situ X-ray CT imaging of transient water retention experiments with cyclic drainage and imbibition
Language: English
Authors: Milatz, Marius

Keywords: Unsaturated granular soils; Water retention behaviour; Transient flow experiments; X-ray computed tomography (X-ray CT)
Issue Date: 26-Apr-2022
Technical Info: 
The data contain 3D tiff images from CT scans, which can be opened using an image reader, e. g., the open-source image processing software Fiji (ImageJ). Further experimental data are stored in simple data or text files which can be read using a dedicated text editor. Data can be visualised and plotted using the accompanying Python scripts in conjunction with matplotlib and numpy.
Abstract (english): 
This data set contains research data related to the article "In situ X-ray CT imaging of transient water retention experiments with cyclic drainage and imbibition" to be published in the Journal Open Geomechanics. The research data include 3D CT images acquired during cyclic drainage and imbibition of a sand specimen in a transient in situ water retention experiment that was run in the X-ray tomograph at Laboratoire 3SR at Univ. Grenoble Alpes. Besides the CT images, also data from the multiphase image analysis as well as macroscopic water retention data, measured in parallel to the CT scans, are published.
