Assessment of Bark Properties from Various Tree Species in Terms of Its Hydrophobicity and Energy Suitability

Energies, 2023
Wood bark is a by-product of the forestry industry with significant quantitative potential. Due to the higher heating value and hydrophobic character (dictated by the content of hydrophobic extracts in the chemical composition of the bark) facilitating ...

بررسی شدت آبگریزی خاک و تغییرات زمانی آن پس از آتش سوزی تجویزی در مناطق جنگلی آبخیز توشن استان گلستان [PDF]

پژوهش‌های حفاظت آب و خاک, 2018
سابقه و هدف: آب‌گریزی خاک (SWR) یکی از خصوصیات پویای خاک است که نفوذ آب در خاک را کاهش داده و یا از آن جلوگیری می‌کند. در مناطق جنگلی شمال کشور، آتش‌سوزی یکی از نگرانی‌های محیطی بسیار مهم و از عوامل اصلی تغییر در پدیده آب‌گریزی خاک است.

Soil water repellency decreases summer maize growth

, 2019
A two-year summer maize irrigation experiment was conducted in soil lysimeters under a rain-shelter to analyze the effects of water repellency on soil moisture, evapotranspiration, crop growth, and yields.

Basic soil properties as a factor controlling the occurrence and intensity of water repellency in rankers of the White Carpathians [PDF]

, 2015
Water repellency in soils is controlled by many different factors, basic physical and chemical properties might be considered the crucial ones. For the purpose of this study, 12 sites were selected and sampled (0–20 cm depth) in the White Carpathians ...

Slope and sediment size in the development of pebble and cobble beaches with low permeability

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
We studied beaches composed of coarse‐grained beaches. In spite that the occurrence of an impermeable layer at a low depth that reduces its permeability, the correlation between the beach slope and the sediment size corresponds to what was expected, and the underlying and cohesive sediment reached the same slope of the beach.

Evaluating Post‐Fire Salvage Logging Erosion Mitigation Treatments in the California Sierra Nevada, USA

Hydrological Processes, Volume 40, Issue 7, July 2026.
Multiple pairs of mitigation treatments including logging slash, subsoiling, traffic passes and slope were evaluated over time using a rill simulation experiment to determine which treatments were effective at reducing runoff and sediment delivery from logged hillslopes.

A modified water drop method for addressing the spatial variability of hydrophobicity within individual pedons

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract The development of hydrophobic layers during wildfire is well‐documented. Tests are often performed on a few points at the mineral soil surface. However, this may not accurately capture the spatial extent of these layers laterally or vertically.

The Effects of Lantana camara L. on Soil Physicochemical Properties in the Eastern Cape Province of South Africa

African Journal of Ecology, Volume 64, Issue 5, July 2026.
ABSTRACT Lantana camara L. is an invasive alien plant species that is recognised globally due to its extensive distribution and negative impacts on species diversity and ecosystem dynamics. Despite its extensive distribution in South Africa, its physicochemical impacts on soils are understudied. This study investigated the impacts of L.

Use of Clay Dispersed in Water for Decreasing Soil Water Repellency : Water Repellency Mitigation [PDF]

, 2017
In this study, we examined the efficiency of a kaolinite clayey soil to mitigate water repellency of a sandy soil with olive trees. The treatment was applied to the soil zone below the tree canopy, which displayed the highest degree of water repellency ...

Modeling of water infiltration in hydrophobic‐over‐wettable two‐layer columns

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract This paper presents a new piecewise model for simulating one‐dimensional infiltration curves in two‐layer finite columns consisting of a hydrophobic layer overlaying wettable soil. The model combines a physics‐based equation for infiltration in water‐repellent substrates with an analytical framework for ponded conditions.
