Study on water retention characteristics of coastal soils in Northern Zhejiang Province

浙江大学学报. 农业与生命科学版, 2001
The water retention characteristics of coastal soils in Zhejiang Province were studied. Results showed that water retention curves of coastal soils were a typical double-curve and the best modal to characterize the relationship between soil water content

Describing the soil physical characteristics of soil samples with cubical splines [PDF]

, 2008
The Mualem-Van Genuchten equations have become very popular in recent decades. Problems were encountered fitting the equations¿ parameters through sets of data measured in the laboratory: parameters were found which yielded results that were not ...

Variation of Water Retention in Various Soils of Kuwait

Archives of Agronomy and Soil Science, 2002
Soil properties varied in water retention; due to soil texture and organic matter content. Variations of texture in many soils are effected mostly to soil forming factors of parent materials of the soil; biological activities; climactic variation; and duration of soil reaction. While the organic matter contents are affected totally by the environmental

Modeling the soil–water retention curves while the soil is deforming [PDF]

Comptes Rendus. Mécanique, 2021
A porous-solid model based on the grain and pore size distributions of the soil is coupled with a mechanical model to simulate the soil–water retention curves while the material is deforming. During the determination of the main drying curve, the soil is subjected to high suctions which induce important volumetric deformations.

Feldspathic sandstone addition and its impact on hydraulic properties of sandy soil [PDF]

, 2018
Feldspathic sandstone could be used as an effective conditioner to improve the physical quality of sandy soil, and increase the crop yield there. To determine the effects of feldspathic sandstone content on soil hydraulic properties in a sandy soil, the ...

A modeling framework to quantify the effects of compaction on soil water retention and infiltration [PDF]

, 2021
The water retention curve (WRC) of arable soils from the southeastern United States at different levels of compaction (no compaction, and 10 and 20% increases in soil bulk density) was estimated using the van Genuchten-Mualem (VG) model.

Forest restoration in tropical forests recovers topsoil water retention but does not improve deep soil layers

International Soil and Water Conservation Research
Tropical primary forests have been rapidly reduced in recent decade owing to slash-and-burn, leading to the formation of tropical secondary forests in different recovery stages.

Impact of Biochar on Water Retention in Soil

IOP Conference Series: Earth and Environmental Science, 2019
Abstract The article presents analysis of retention properties of mineral soil formations enriched with biochar and an attempt was made to characterise the states of hydration. Due to a complex and time-consuming process of direct measurement of hydration and retention soil characteristics (the so-called pF curve). The paper investigates

Analysis of the suitability of Polish soil texture classification for estimating soil water retention and hydraulic properties

Soil Science Annual, 2017
The objective of this study was to examine whether the Polish soil textural classification is useful for evaluation of soil water retention and hydraulic properties and, furthermore, for determining which textural classes are characterized by the highest
