Soils ranging in texture from sand to clay were used to compare permittivity measurements made using a Surface Capacitance Insertion Probe (SCIP) and time domain reflectometer (TDR). Measurements were made using the same electrodes embedded in each s

calculated permittivity values for the sand compare reasonably well with Topp’s equation. The permittivity in the sandy loam to silt loam Of these, transmission line oscillators are particularly soils is overestimated by as much as 104 dimensionles

The capacitance (CAP) method and time domain reflectometry (TDR) are two popular electromagnetic techniques used to estimate soil water content. However, the frequency dependence of the real and imaginary part of the permittivity complicates sensor c

Capacitance probe sensors are a popular electromagnetic method of measuring soil water content. However, there is concern about the influence of soil salinity on the sensor readings. In this study capacitance sensors are calibrated for a saline silty

SUMMARY The farmers of the South-West Punjab, India, lift fresh groundwater for irrigation from the upper layers of the aquifers through interconnected, shallow, and low discharge tube wells. The groundwater of higher salinity usually present at deep

Coalbed natural gas (CBNG)-produced water contains small amounts of trace metals that can accumulate over time in produced water retention ponds. Within the Powder River Basin (PRB) of Wyoming, high concentrations of trace metals in pond water and th
