Wetting Front Velocity Determination in Soil Infiltration Processes: An Experimental Sensitivity Analysis

Agronomy, 2022
An experimental approach for measuring the wetting front velocity in soils during water infiltration processes is presented. This experimental research is developed to test the sensitivity of the measurement technique in the detection of differences in ...

Occurrence of temperature spikes at a wetting front during spontaneous imbibition [PDF]

Scientific Reports, 2017
It is reported that temperature rises at wetting front during water infiltration into soil. The temperature goes back to the background value after passage of water front. Different explanations have been provided for source of energy causing temperature

Automatic framework for extraction and characterization of wetting front propagation using tomographic image sequences of water infiltrated soils. [PDF]

PLoS ONE, 2015
This paper presents a new automatic framework for extracting and characterizing the dynamic shape of the 3D wetting front and its propagation, based in a sequence of tomographic images acquired as water (moisture) infiltrates in unsaturated soils. To the

Improving seepage characteristics of strongly weathered mudstone slopes with rice husk ash [PDF]

Scientific Reports
Strongly weathered mudstone slopes in northern Hebei Province are susceptible to rainfall-induced instability due to their swelling and shrinkage properties. This study investigates rice husk ash (RHA), an agricultural waste byproduct, as an amendment to

Study on the stability analysis of rainfall slope based on G-A model considering moisture content

Scientific Reports, 2022
In this paper, the moisture content on the wetting front is obtained by using the Van Genuchten (VG) model of unsaturated soil, and then the distribution of moisture content in the upper part of the wetting front is simplified as a trapezoid.

Wetting Front Expansion Model for Non-Ponding Rainfall Infiltration in Soils with Uniform and Non-Uniform Initial Moisture Content

Applied Sciences, 2022
The rainfall infiltration model plays a key role in the fields of seepage theory and geological hazard evaluation. To reflect the change in the moisture content in soil during rainfall infiltration, the infiltration process was segmented into stages, and

Laboratory Acousto‐Mechanical Study Into Moisture‐Induced Reduction of Fracture Stiffness in Granite

Geophysical Research Letters, 2023
Water infiltration into fractures is ubiquitous in crustal rocks. However, little is known about how such a progressive wetting process affects fracture stiffness and seismic wave propagation, which are highly relevant for characterizing fracture systems

Wet front propagation for water jet impingement on flat surface

Alexandria Engineering Journal, 2018
A casted leaded-bronze block was impinged by a circular water jet. A 30-fps digital camera was used to video record the wet front propagation process on the surface of the block.

Influence of hydraulic-mechanical coupling and dry-wet cycle effect on surficial layer stability of residual soil slopes

Zhongguo dizhi zaihai yu fangzhi xuebao, 2022
During rainfall infiltration, soil suction decreased and volume changed significantly. Since the natural shallow soil was under the influence of seasonal climate changes for a long time, numerical analysis of the influence of hydraulic-mechanical ...
