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 (

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.

Soil water retention curves determined in the laboratory and in the field
2022<p>Soil water retention curves (SWRCs) provide information on the energy status of soil water and its availability to plants and are therefore important for irrigation management. SWRCs have traditionally been determined in the laboratory.

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.

Modeling Soil Water Retention Curve with a Fractal Method
Pedosphere, 2006ABSTRACT Many empirical models have been developed to describe the soil water retention curve (SWRC). In this study, a fractal model for SWRC was derived with a specially constructed Menger sponge to describe the fractal scaling behavior of soil; relationships were established among the fractal dimension of SWRC, the fractal dimension of soil mass ...

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.

An Improved Fractal Equation for The Soil Water Retention Curve
Water Resources Research, 1996The water retention curve, θ(ψ), is important for predicting soil physical properties and processes. Until recently, equations for the θ(ψ) were empirical. Advances in fractal geometry have led to the derivation of physical models for the θ(ψ). However, both existing fractal equations have only two parameters and thus are relatively inflexible.

Aerodynamic method for obtaining the soil water retention curve
Eurasian Soil Science, 2013A new method for the rapid plotting of the soil water retention curve (SWRC) has been proposed that considers the soil water as an environment limited by the soil solid phase on one side and by the soil air on the other side. Both contact surfaces have surface energies, which play the main role in water retention.
