Soil moisture content has paramount importance in dictating engineering, agronomic,
geological, ecological, biological and hydrological characteristics of the soil mass. Though …

Substantial advances in the measurement of water content and bulk soil electrical
conductivity (EC) using time domain reflectometry (TDR) have been made in the last two …

Droughts, typically caused by the deficiencies of precipitation and soil moisture, affect water
resources and agriculture. As soil moisture is of key importance in understanding the …

The capacitance (CAP) method and time domain reflectometry (TDR) are two popular
electromagnetic techniques used to estimate soil water content. However, the frequency …

This paper presents a review of techniques for field measurement of suction, water content,
and water hydraulic conductivity (permeability). Main problems in the use of field …

This is the first of two articles that present experimental spectra of six soil samples with
varying clay contents ranging from 0% to 55% and organic carbon levels ranging from 0% to …

Field monitoring of volumetric soil water content (VWC) is critical for a variety of applications.
Recently developed electronic soil water sensors provide a relatively inexpensive …

Soil and environmental studies in the vadose zone are often restricted by the lack of
equipment that can measure the variation of soil physical parameters in space and time. In …

Time domain reflectometry (TDR) has become one of the standard methods for the
measurement of the temporal and spatial distribution of water saturation in soils. Current …

Soil water content measurement is critical in practical engineering. The actively heated fiber
Bragg grating optic sensor (FBGS) has great potential of multi-point measurement for soil …
