High intenxity X-ray and tensiometer measurements in rapidly changing preferential flow fields

A new high-resolution quantitative method of examining quick alterations of the fluid amount present in porous media, was provided by synchrotron X-rays at the Cornell High Energy Synchrotron Source. This method is founded on controlling X-ray absorbance alterations in sand volumes crossed by an acute, highly collimated synchrotron X-ray beam. This method helps assess the physical and chemical characteristics of a rapid flow field in porous media.
