Thermohydraulic experiments on water infiltration into frozen slopes: the role of macropores and initial water content [PDF]
The CryosphereInfiltration of rainwater or snowmelt into frozen soil is strongly constrained by ice-blocked pore spaces, depending on the thermal and hydrological state.

Effect of initial water content on the pyrolysis mechanism of lignocellulosic biomass
BiocharThe initial water content in lignocellulosic biomass significantly influences the pyrolysis process, but the effect of the form of water, especially free water (FW) and bound water (BW), remains unclear.

Effect of Initial Water Content on the Properties of Compacted Expansive Unsaturated Soil
Journal of Engineering, 2015 Unsaturated soil can raise many geotechnical problems upon wetting and drying resulting in swelling upon wetting and collapsing (shrinkage) in drying and changing in the soil shear strength.

Compression behaviour of reconstituted soils at high initial water contents [PDF]
Géotechnique, 2010 Oedometer tests starting from a very small effective vertical stress of 0·5 kPa were performed on three reconstituted clays with different liquid limits. The soils were prepared at various initial water contents, ranging from 0·7 to 2·0 times their corresponding liquid limits. It is observed that the e–log [Formula: see text] compression curves show an

Effect of initial water content and pore water chemistry on intrinsic compression behavior [PDF]
Marine Georesources & Geotechnology, 2018 The effect of initial water content (w0) and pore water chemistry on the intrinsic compression curve of clays was investigated experimentally. The test results indicate that w0 had a considerable effect on the intrinsic compression curve of a clay, and the degree of the effect is a function of pore water chemistry.

Advances in Civil Engineering, 2021 Expansive soil has the property of water swelling, which is related not only to the hydrophilic mineral composition of soil particles and the microstructure of soil, but also to the initial moisture content, dry density, and overburden condition of soil.

Compression behavior and structure of undisturbed Q2 loess under wet-dry cycles
Soils and Foundations, 2022 In the Loess Plateau of China, the undisturbed Q2 loess is in a state of wet-dry cycles due to seasonal rainfall and groundwater level fluctuations. The root cause of large deformation and poor stability of engineering foundation caused by wet-dry cycles

Influence factors for “pot-cover effect”
Yantu gongcheng xuebao, 2018 When the surface of the unsaturated soils is covered by a water and air proof layer, the water content of the shallow soils will increase with time. This phenomenon is considered as the “pot-cover effect”.
