Long-Term Soil-Water Tension Measurements in Semiarid Environments: A Method for Automated Tensiometer Refilling

Vadose Zone Journal, 2018
Tensiometer-equipped data acquisition systems measure and record positive and negative soil-water pressures. These data contribute to studies in hillslope hydrology, including analyses of rainfall runoff, near-surface hydrologic response, and slope ...

Molecular‐Level Pore Engineering for Precise Separation via Active Solvent‐Mediated Interfacial Polymerization [PDF]

Advanced Science, EarlyView.
We demonstrate that microemulsion solvents can actively template molecular‐level pores within selective layer during interfacial polymerization. By creating localized quasi‐homogeneous polymerization zones, the membrane achieved a 7.1‐fold enhancement in water permeance with increased selectivity.

Measuring very negative water potentials with polymer tensiometers: principles, performance and applications [PDF]

, 2009
In recent years, a polymer tensiometer (POT) was developed and tested to directly measure matric potentials in dry soils. By extending the measurement range to wilting point (a 20-fold increase compared to conventional, water-filled tensiometers), a ...

Experimental Study on Determining Unsaturated Property of Soil [PDF]

, 1980
This paper deals with the experimental study of hydraulic properties of unsaturated soil. In treating unsaturated zone, a great deal more data are required than are required for the saturated zone, but these properties of soils must be known to apply the

Evaluation of soil water storage in native forest and eucalyptus areas

Revista Ambiente & Água, 2017
In the region of the Paraíba do Sul river valley in the State of São Paulo, Brazil, pasture areas have been replaced by eucalyptus plantations, which can modify the dynamics of water in the soils of the region.

An Investigation into the Water Retention Behaviour of an Unsaturated Natural Fissured Clay

Applied Sciences, 2022
The presence of intensely fissured soils is often found to relate to high geotechnical risks, such as landslide risk. This is especially the case of the Southern Apennines, Italy, where slopes formed of intensely fissured clays are frequently affected by

Polymer tensiometers with ceramic cones: direct observations of matric pressures in drying soils [PDF]

, 2010
Measuring soil water potentials is crucial to characterize vadose zone processes. Conventional tensiometers only measure until approximately −0.09 MPa, and indirect methods may suffer from the non-uniqueness in the relationship between matric potential ...

An Alternative Tensiometer Design for Deep Vadose Zone Monitoring [PDF]

, 2015
The conventional tensiometer is among the most accurate devices for soil water matric potential measurements, as well as for estimations of soil water flux from soil water potential gradients.

Sensor placement for soil water monitoring in lemon irrigated by micro sprinkler Posicionamento de sensores para monitoramento de água no solo em limoeiro irrigado por microaspersão

Revista Brasileira de Engenharia Agrícola e Ambiental, 2007
This research had as its objective the investigation of an alternative strategy for soil sensor placement to be used in citrus orchards irrigated by micro sprinkler. An experiment was carried out in a Tahiti lemon orchard under three irrigation intervals
