Effect of Particle Size on Droplet Infiltration into Hydrophobic Porous Media As a Model of Water Repellent Soil [PDF]

, 2011
The wettability of soil is of great importance for plants and soil biota, and in determining the risk for preferential flow, surface runoff, flooding,and soil erosion. The molarity of ethanol droplet (MED) test is widely used for quantifying the severity

Assessment of Physical Properties of Water-Repellent Soils [PDF]

Journal of Geotechnical and Geoenvironmental Engineering, 2021
This note presents a comprehensive characterization of physical and mechanical properties of water repellent (hydrophobic) soil collected from Cleveland National Forest in California immediately after the Holy Fire, 2018, and delineates comparisons with chemically induced hydrophobic sand in the laboratory.

Water repellency in forest soils affected by fires and agricultural soils with different agricultural management and abandonment

Cuadernos de Investigación Geográfica, 2013
Soil water repellency determines the water available in the soil system, the runoff generation and the geomorphologic processes. This study examines the soil wettability during the summer of 2008 and 2009 in forest soils with different fire history, and ...

Impact of secondary succession in abandoned fields on some properties of acidic sandy soils

Journal of Hydrology and Hydromechanics, 2020
Abandonment of agricultural lands in recent decades is occurring mainly in Europe, North America and Oceania, and changing the fate of landscapes as the ecosystem recovers during fallow stage.

Morphology of rain water channelization in systematically varied model sandy soils [PDF]

, 2014
We visualize the formation of fingered flow in dry model sandy soils under different raining conditions using a quasi-2d experimental set-up, and systematically determine the impact of soil grain diameter and surface wetting property on water ...

Water entrance-and-release capacity and contact angle of improved granite residual soil

Shuiwen dizhi gongcheng dizhi, 2022
Water entrance-and-release capacity of granite residual soil is closely related to the special mechanical properties of softening and disintegration. Existing research on the improved soil focuses on the macro-mechanical properites and variation of micro-

Critical conditions for the wetting of soils [PDF]

, 2006
The wettability of soil is of great importance for plants and soil biota and in determining whether flooding and soil erosion will occur. The analysis used in common measurements of soil hydrophobicity makes the assumption that water always enters soils ...

Microbial Effects on Hydraulic Properties of Sewage Sludge-Induced Water-Repellent Soil. [PDF]

Desert
Soil water repellency (SWR) is a widespread natural phenomenon that results from a complex interplay between the hydrosphere, lithosphere, biosphere, atmosphere, and anthroposphere.

Ground Fire Legacy Effects on Water-Dynamics of Volcanic Tropical Soils

Spanish Journal of Soil Science, 2023
The forest floor is a critical component in maintaining the life cycles of forest ecosystems. It normally includes organic soil horizons, known as duff and litter, which are prone to be rapidly consumed after flaming and smoldering fires.

Soil Infrastructure, Interfaces & Translocation Processes in Inner Space (“Soil-it-is”): Towards a Road Map for the Constraints and Crossroads of Soil Architecture and Biophysical Processes [PDF]

, 2009
Soil functions and their impact on health, economy, and the environment are evident at the macro scale but determined at the micro scale, based on interactions between soil micro-architecture and the transport and transformation processes occurring in ...
