Application of minidisk infiltrometer to estimate water repellency in Mediterranean pine forest soils [PDF]

Journal of Hydrology and Hydromechanics, 2017
Assessment of soil water repellency (SWR) was conducted in the decomposed organic floor layer (duff) and in the mineral soil layer of two Mediterranean pine forests, one in Italy and the other in Spain, by the widely-used water drop penetration time ...

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.

The Effect of Heating on Properties of Sandy Soils [PDF]

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.

Soil seal development under simulated rainfall: Structural, physical and hydrological dynamics. [PDF]

J Hydrol (Amst), 2018
This study delivers new insights into rainfall-induced seal formation through a novel approach in the use of X-ray Computed Tomography (CT). Up to now seal and crust thickness have been directly quantified mainly through visual examination of sealed ...

Extent and persistence of soil water repellency induced by pines in different geographic regions [PDF]

Journal of Hydrology and Hydromechanics, 2018
The extent (determined by the repellency indices RI and RIc) and persistence (determined by the water drop penetration time, WDPT) of soil water repellency (SWR) induced by pines were assessed in vastly different geographic regions.

Impacts of thinning of a Mediterranean oak forest on soil properties influencing water infiltration [PDF]

Journal of Hydrology and Hydromechanics, 2017
In Mediterranean ecosystems, special attention needs to be paid to forest–water relationships due to water scarcity. In this context, Adaptive Forest Management (AFM) has the objective to establish how forest resources have to be managed with regards to ...

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.

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.

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.
