Wettability decay in an oil-contaminated waste-mineral mixture with dry-wet cycles [PDF]
, 2015 The dependency of soil particle wettability on soil water content implies that soils subjected to drying-wetting cycles become wettable with wetting and water repellent with drying.

Water stable aggregates of Japanese Andisol as affected by hydrophobicity and drying temperature
Journal of Hydrology and Hydromechanics, 2014 Hydrophobicity is a property of soils that reduces their affinity for water, which may help impeding the pressure build-up within aggregates, and reducing aggregate disruption.

Soil hydrophobicity: comparative study of usual determination methods
Ciência Rural, 2015 Hydrophobic or water repellent soils slowly absorb water because of the low wett ability of the soil particles which are coated with hydrophobic organic substances. These pose significant effects on plant growth, water infiltration and retention, surface

Implications of ideas on super-hydrophobicity for water repellent soil [PDF]
, 2007 Water repellence is an important factor in soil erosion due to its role in inhibiting the re-establishment of vegetation after fire and due to its enhancement of run-off.

Effect of kaolinite and Ca-montmorillonite on the alleviation of soil water repellency
Plant, Soil and Environment, 2004 The effects of adding 1-3% (weight) kaolinite or Ca-montmorillonite on the wettability of silica sand, made highly water repellent with stearic acid, was studied during wetting and prolonged drying phases at 50°C.

Processes in model slopes made of mixtures of wettable and water repellent sand: Implications for the initiation of debris flows in dry slopes [PDF]
, 2015 Debris flows in slopes initially dry, such as post-wildfire debris flows, are initiated by surface runoff and sediment bulking due to reduced infiltration.

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.

Does Spontaneous Secondary Succession Contribute to the Drying of the Topsoil?
Forests, 2023 The aim of the study was to analyse the moisture content (θ) and the persistence and strength of water repellency (SWR) on sandy soil excluded from cultivation and then undergoing spontaneous afforestation or weed infestation during an abnormally warm ...

The tractability frontier of well-designed SPARQL queries
, 2018 We study the complexity of query evaluation of SPARQL queries. We focus on the fundamental fragment of well-designed SPARQL restricted to the AND, OPTIONAL and UNION operators.
