Determination of the Soil Water Retention Curve with Tensiometers
2007An alternative technique for the determination of the soil water retention curve has recently been proposed whereby a tensiometer is used to measure soil suction and a balance to record the water content variations. The soil water retention curve is obtained by drying the soil either continuously or by stages (i.e.

An Improved Volume Measurement for Determining Soil Water Retention Curves
Geotechnical Testing Journal, 2007Abstract The complete determination of soil water retention curves requires the sample volume to be measured in order to calculate its void ratio and degree of saturation. During drying in the pressure plate apparatus, cracks often appear in the sample altering its deformation and evaporation patterns.

A Technique for Producing Soil Water Retention Curves
South African Forestry Journal, 1990SYNOPSIS Water retention curves compiled for specific soil types are an essential management and research tool in evaluating plant stress. The method of producing water retention curves by means of the 1500 kPa pressure extractor is described.

Estimation of the soil water retention curve using penetration resistance curve models
Computers and Electronics in Agriculture, 2018Abstract In this study, pedotransfer functions (PTFs) were developed for estimating the gravimetric water content based on the model of Dexter et al. (2008) using feed-forward artificial neural networks. Soil samples were collected from 148 locations in the West Azarbaijan, Hamedan, Fars, and Kurdistan provinces of Iran. The cation exchange capacity (

The influence of salinity on hysteresis of soil water‐retention curves
Hydrological Processes, 2012AbstractTaiwan is surrounded by the sea, and the southwestern seashores are suffering from a growing land subsidence problem caused by the excessive extraction of groundwater. There is also very serious intrusion by seawater along the coastline. These circumstances obstruct any land use, soil remediation or agriculture development in the area.

Diagnostics of Desertification with the Use of Water Retention Curve of Soils
Arid Ecosystems, 2016Based on a study of processes developed upon desertification (salinization, solonetzization, and sand accumulation) in the soils of the Caspian Sea Lowland, it is shown that soil’s water retention capacity may be used as an integral parameter of all desertification trends. It is characterized by the water retention curve (WRC).

Soil water retention curves based on idealized models
Russian Agricultural Sciences, 2013Energy consideration of soil moisture as a medium bounded by the soil air and the soil solid phase allows us to obtain the water retention curve (WRC). A pedotransfer function (PTF) reflects approximations and simplifications made in the soil modeling.
