Ground-penetrating radar (GPR, also referred to as ground-probing radar, surface-
penetrating radar, subsurface radar, georadar or impulse radar) is a noninvasive …

We present a comprehensive review of methods to measure soil water content with ground
penetrating radar (GPR). We distinguish four methodologies: soil water content determined …

Preferential flow, a major influence in unsaturated soil and rock almost everywhere, occurs
by multiple phenomenologically distinct hydraulic processes. For the mode known as …

A complete treatment of the theory and practice of groundwater engineering, The Handbook
of Groundwater Engineering, Second Edition provides a current and detailed review of how …

Introduction Ground-penetrating radar (GPR) is a relatively young geophysical technique.
First uses appeared in the 1960s with radio echo sounding of glaciers and ice sheets (Bailey …

The generation of sulfate radicals is a key factor to limit the catalytic activities of sulfate
radical-based advanced oxidation processes (SR-AOPs). Microwave irradiation is a specific …

Soil moisture sensing is one of the most important components in smart agriculture. It plays a
critical role in increasing crop yields and reducing water waste. However, existing …

Cross-borehole geoelectrical imaging, in particular electrical resistivity tomography (ERT)
and transmission radar tomography, can provide high-resolution images of hydrogeological …

Ground-penetrating radar (GPR) reflection travel time data were used to estimate changes in
soil water content under a range of soil saturation conditions throughout the growing season …

Near-surface geophysics uses the investigational methods of geophysics to study the nature
of the very outermost part of the earth's crust. Man interacts with this part of the earth's crust …
