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.

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.

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 ...

Short-term impact of different doses of spent coffee grounds, salt, and sand on soil chemical and hydrological properties in an urban soil. [PDF]

Environ Sci Pollut Res Int, 2023
Natural and human activities have deteriorated urban soil’s health and ecological functions as compared to forest soils. Therefore, we hypothesized that any intervention in poor quality soil in urban area will change their chemical and water retention ...

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 ...

The kinetics and energetics of transitions between water repellent and wettable soil conditions: a linear free energy analysis of the relationship between WDPT and MED/CST

Hydrological Processes, 2007
AbstractSoil water repellency is commonly assessed using the Water Droplet Penetration Time (WDPT) and Molarity of Ethanol (MED) or Critical Surface Tension (CST) tests. The former is a kinetic measurement indicating the persistence of water repellency; the latter, a thermodynamic measurement, gives the initial severity of water repellency.

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 ...

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 ...
