A machine learning framework to measure Water Drop Penetration Time (WDPT) for soil water repellency analysis

Machine Learning with Applications
The heat from wildfires volatilizes soil’s organic compounds which form a waxy layer when condensed on cooler soil particles causing soil to repel water.

Synchrotron-radiation computed tomography of the water drop penetration time test on hydrophobic soils

Journal of Rock Mechanics and Geotechnical Engineering
The water drop penetration time (WDPT) test consists of placing water drops on a material's surface in order to evaluate how long it takes to penetrate the pores. It is used to evaluate the hydrophobicity of materials. This study aims at investigating in

Evaluation of a Method to Induce Hydrophobicity on Sand

HortScience, 2023
Methods to evaluate soil water repellency (SWR) require extensive studies on field soils and are subject to the heterogeneity of SWR throughout the soil profile as well as plant/soil interactions.

Water–soil interactions: Unravelling the processes and stages involved in the wetting of water repellent soils

Journal of Hydrology X, 2023
The water repellent behaviour of soils is a widely studied phenomenon given its implications for infiltration, runoff, erosion and preferential flow. However, the principles underlying the eventual penetration of water into affected soils remain poorly ...

The Effect of Heating on Properties of Sandy Soils

Land, 2023
Although burning grass and crop residues is prohibited in many countries, farmers perceive it as a quick and inexpensive way to eliminate unwanted biomass.

Intensity and persistence of water repellency at different soil moisture contents and depths after a forest wildfire

Journal of Hydrology and Hydromechanics, 2022
The Mediterranean mixed coniferous and broad-leaved forest of Moarda (Palermo) was affected by a large wildfire in summer 2020. In spring 2021, burned and unburned loam soil sites were sampled and the water drop penetration time (WDPT) and ethanol ...

Impact of Duration of Land Abandonment on Infiltration and Surface Runoff in Acidic Sandy Soil

Agriculture, 2022
Sandy soils are less fertile and, therefore, often abandoned in the Central European region. Land abandonment can cause the recovery of ecosystems by the replacement of crop species by vegetation that disperses from surrounding habitats and will be ...

Fire-induced changes in soil properties depend on age and type of forests

Journal of Hydrology and Hydromechanics, 2022
Wildfires affect different physical, chemical, and hydraulic soil properties, and the magnitude of their effects varies depending on intrinsic soil properties and wildfire characteristics.

On the resistance of hydrophobic soil polymer coatings created by cold plasma polymerization [PDF]

E3S Web of Conferences, 2023
Hydrophobic soils have natural or artificial origin. In this context, some techniques exist to turn into hydrophobic sand that was originally hydrophilic, as most soils in fact are.

Wet granulation in laboratory-scale high shear mixers: Effect of chopper presence, design and impeller speed [PDF]

, 2011
The effect of the main means of agitation in a high shear mixer has been investigated in this study. Granulation runs have been performed on a fine cohesive microcrystalline cellulose powder (Avicel 105, d50 = 20 μm) often used as a pharmaceutical ...
