Assessing Relation of Soil Hydrophobicity and Soil Water Content and Determining Threshold Moisture of Organic Soil Samples
Soil water content is the most effective factor associated with the hydrophobic and hydrophilic changes in a soil. Water repellency in soils, is not a permanent feature; it can be reached in the dry season and reduced or eliminated in the wet season It can be said that in terms of moisture, there is a critical region that is defined as the threshold moisture content, where in lower moisture, th...
متن کاملAn algorithm for soil moisture estimation using GPS-interferometric reflectometry for bare and vegetated soil
Ground-reflected global positioning system signals measured by a geodetic-quality GPS system can be used to infer temporal changes in near-surface soil moisture for the area surrounding the antenna. This technique, known as GPS-interferometric reflectometry, analyzes changes in the interference pattern of the direct and reflected signals, which are recorded in signal-to-noise ratio (SNR) data, ...
متن کاملDetermining Soil Moisture Rapidly and Accurately by Methyl Alcohol.
In a former communication* the use of alcohol was proposed as a basis for a very rapid means of determining the moisture content of soils and possibly of other materials. Th~ form of alcohol that was then suggested was ethyl alcohol. In order to ascertain whether there are other liquids that would be more satisfactory than ethyl alcohol, an investigation has been conducted in which a large numb...
متن کاملUptake in Vegetated Soil Columns
Investigations are currently being conducted at Imperial College into the upward migration of radionuclides from a contaminated water table and their subsequent uptake by plant root systems. This programme includes both experimental studies and related mathematical modelling. Previous work has been primarily with lysimeters. However, these experiments are expensive and somewhat lengthy and the ...
متن کاملA Combined Optical-Microwave Method to Retrieve Soil Moisture Over Vegetated Areas
1 Abstract— A simple approach for correcting the effect of vegetation in the estimation of the surface soil moisture (w S) from L-band passive microwave observations is presented in this study. The approach is based on semi-empirical relationships between soil moisture and the polarized reflectance including the effect of the vegetation optical depth which is parameterized here as a function ...
