TL;DR: Temperature measurements in temporarily sealed boreholes not only improve the sensitivity and accuracy of identifying hydraulically active fractures under ambient conditions but also offer new insights regarding previously unresolvable flow distributions in fractured rock systems, while leaving the borehole available for other forms of testing and monitoring device installation.

TL;DR: In this paper, the authors developed equipment for straddle packer testing in fractured-rock boreholes to conduct four types of tests (constant head step tests, slug tests, constant rate pumping tests, and recovery tests) without deflating the packers or adjusting equipment in the hole between tests.

TL;DR: Keller et al. as discussed by the authors studied the spatial variability of hydrogeochemical processes within an 18m-thick unit of clay-ey till beneath a flat prairie landscape.

TL;DR: In this paper, the authors describe a study in southern Wisconsin where vertical hydraulic head profiles measured in exceptional detail provided the key data for defining hydrogeologic units (HGUs) in a layered sequence of sandstone, siltstone, shale, and dolostone.

TL;DR: In this paper, an analytical mathematical model was developed for the simulation of the radial movement of a contaminant front away from an injection point under steady flow conditions in a planar fracture with uniform properties.
