Recently, the rapid increase in tunnel construction in karst areas across China has attracted
considerable attention. However, frequently occurring groundwater inrush hazards induced …

High‐pressure packer test (HPPT) is an enhanced constant head packer test for
characterizing the permeability of fractured rocks under high‐pressure groundwater flow …

We show how a distributed borehole flowmeter can be created from armored Fiber Optic
cables with the Active‐Distributed Temperature Sensing (A‐DTS) method. The principle is …

This work reviews various studies of hydraulic and pneumatic tomography for estimation of
flow properties of fractured geologic media with hydraulic and pneumatic tomography. The …

High-pressure packer test (HPPT) is an enhanced constant head packer test for
characterizing the permeability or coupled hydromechanical properties of fractured rocks …

In sparse fracture systems flow and transport patterns are often dominated by main
flowpaths and characterized by a strong complexity induced by the fractures' surface …

Abstract Between 2005 and 2010, Japan Atomic Energy Agency conducted four long-term,
independent pumping tests in a fractured granite formation at the Mizunami Underground …

The detection of preferential flow paths and the characterization of their hydraulic properties
are major challenges in fractured rock hydrology. In this study, we propose to use …

In this study, in situ water injection tests and numerical modeling in conjunction with core
logs and television image measurements were applied for an investigation of the hydraulic …

We present the first demonstration of hydraulic tomography (HT) to estimate the three‐
dimensional (3D) hydraulic conductivity (K) distribution of a fractured aquifer at high …
