Water Resources Research, Volume 60, Issue 3, March 2024.Abstract Per‐ and poly‐fluoroalkyl substances (PFAS) are interfacially‐active contaminants that adsorb at air‐water interfaces (AWIs). Water‐unsaturated soils have abundant AWIs, which generally consist of two types: one is associated with the pendular rings of water between soil grains (i.e., bulk AWI) and the other arises from the thin water films ...

Differentiation of the Material Composition of Lviv Region Luvic Greyzemic Chernozems (Ukraine) [PDF]
, 2017 The soil formation within the Wet Atlantic Chernozem facies of the West-Ukrainian region leads to the vertical redistribution of Chernozem soil substance and formation of the differentiated mineral soil profile to varying degrees by carbonates, clay, and

Hydrological Processes, Volume 38, Issue 2, February 2024.This work uses water isotopic compositions to investigate source water dynamics in semi‐arid agricultural systems where water supply is limited, yet cultivation is pervasive. Comparing water isotopic compositions across landscape areas allows for the interpretation of precipitation infiltration, mixing, and evapotranspiration processes.

Earth and Space Science, Volume 11, Issue 2, February 2024.Abstract The frequency, severity, and spatial extent of destructive wildfires have increased in several regions globally over the past decades. While direct impacts from wildfires are devastating, the hazardous legacy of wildfires affects nearby communities long after the flames have been extinguished.

Importance of background threshold value development within risk‐based corrective action programs
Vadose Zone Journal, Volume 23, Issue 1, January/February 2024.Abstract Risk‐based corrective action (RBCA) programs employ conservative models to develop default values for soil screening, which simplify the risk assessment process. However, for several naturally occurring metals (e.g., arsenic and lead), these published screening values are often unrealistic and well below the documented background levels in ...

Optimization of Irrigation Requirements for the Markonahalli Command Area Using the SWAT Model
Journal of Engineering, Volume 2024, Issue 1, 2024.Irrigation requirements are instrumental in planning water distribution and reservoir management. The Markonahalli Dam is constructed across the Shimsha River and has a command area of 7000 ha in Kunigal Taluk of Tumkur District, Karnataka. It is a semiarid region that depends on canal irrigation from the reservoir.

Tracing the source of soil organic matter eroded from temperate forest catchments using carbon and nitrogen isotopes [PDF]
, 2016 Soil erosion continuously redistributes soil and associated soil organic matter (SOM) on the Earth's surface, with important implications for biogeochemical cycling of essential elements and terrestrial carbon sequestration.

Trends of the natural evolution of chernozems on the East European Plain [PDF]
, 2010 A generalized chronosequence of changes in the morphometric parameters of chernozems in the past 5100 years is analyzed. It is shown that the development of chernozems in the center of the East European Plain is characterized by both longterm ...
