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. Timely assessment of soil water repellency (SWR) is critical for prediction and prevention of detrimental impacts of hydrophobic soils such as soil erosion, reduced availability of water to plants ...

Effect of Biomass-Burning Emissions on Soil Water Repellency: A Pilot Laboratory Study

Fire, 2021
While western U.S. wildfires have increased in intensity and scale, their impacts on soil chemical composition and hydraulic processes have received little attention, despite increasing erosion, surface runoff and flooding.

Comparison of Water-Repellent Detection Agents and Evaluation System Optimization of Soil Water-Repelling Rate

Advances in Civil Engineering
The determination and evaluation of severity rating of soil is an important part of the research on the engineering properties of water-repellent soil. It is still difficult to accurately obtain the soil water-repelling rate in essence, and there are a ...

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

Time-dependent hydrophobic characterisation of granular materials synthesised with commercial chemical agents [PDF]

E3S Web of Conferences, 2023
The impact of hydrophobicity on unsaturated granular materials is important because suction is a function of the degree of saturation as well as the surface tension and contact angle of the water menisci.

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 ...

Modification of Soil Hydroscopic and Chemical Properties Caused by Four Recent California, USA Megafires

Fire, 2023
While it is well known that wildfires can greatly contribute to soil water repellency by changing soil chemical composition, the mechanisms of these changes are still poorly understood.

Impact of duration of land abandonment on soil properties

Journal of Hydrology and Hydromechanics, 2023
Abandonment of agricultural fields triggers the ecosystem recovery in the process referred to as secondary succession. The objective of this study was to find the impact of secondary succession during 12 years lasting abandonment of agricultural fields ...

The effects of different biochar‐dairy manure co‐composts on soil moisture and nutrients retention, greenhouse gas emissions, and tomato productivity: Observations from a soil column experiment

Agrosystems, Geosciences &Environment, Volume 6, Issue 3, September 2023., 2023
Abstract Finding feasible solutions for sustainable food production is challenging. Here we try to understand the balance between crop productivity and ecological stewardship using agroecological‐based soil management strategies. We evaluated the potential of different organic materials such as dairy manure compost and different biochar manure co ...
