Joint multiscale dynamics in soil–vegetation–atmosphere systems: Multifractal cross-correlation analysis of arid and semiarid rangelands

Ecosystems are highly interacting systems, where some changes can produce surprising outcomes (complex systems). A recent study explores the relationships among various ecological components of rangelands in Madrid and Almeria (Spain) (pictured) to aid rangeland managers. Using multifractal analysis, which studies the behavior of time series, the authors compare the behavior and the influence of different environmental factors like precipitation or biomass. Their insights suggest that rangeland management strategies should be tailored to the specific conditions of each region to improve sustainability and productivity. Read more.

Modeling compaction effects on soil water retention across the full moisture range: Calibration and validation

  •  13 February 2025

Core Ideas

  • The effect of compaction on soil water retention curve is modeled across the full moisture spectrum.
  • Successful model calibration was achieved with only one estimated parameter.
  • Other model parameters can either be held constant or predicted from physical reasoning.
  • Only reference curve and bulk density are required for predicting water retention curve of compacted soil.
  • We hypothesize that the approach is independent of the model used to parametrize the pore-size distribution.

Review of conceptual and empirical approaches to characterize infiltration

  •  11 February 2025

Core Ideas

  • A total of 138 unique infiltration models were identified, spanning a wide range of theoretical and empirical boundaries.
  • The proliferation of infiltration models created challenges for researchers in identifying which models to use.
  • Extracting Ksat and sorptivity from infiltration data becomes a challenge with the increased number of models.
  • Most of the developed infiltration models clustered theoretically around few early major milestones

A simple experiment to trace stemflow infiltration: Advantages and challenges of using stable isotopes of hydrogen and oxygen and electrical resistivity tomography

  •  7 February 2025

Core Ideas

  • Stable isotopes of hydrogen and oxygen and time-lapse ERT were successfully applied to study stemflow infiltration.
  • Estimates of stemflow infiltration area were larger than those found in the literature.
  • Experiments based on time-lapse ERT are more effective and less invasive than those based on isotopic tracers.

Insights into freeze–thaw and infiltration in seasonally frozen soils from field observations

  •  5 February 2025

Core Ideas

  • Partitioning of snowmelt between infiltration and runoff is critically important in seasonally frozen soils, with important implications for flooding, soil moisture, and groundwater recharge.
  • Soil temperature, freezing depth, and infiltration capacity at the time of snowmelt depend on multiple confounding factors, namely, snow water equivalent, air temperature, soil water content, and water table depth.
  • Infiltration, drainage, and groundwater recharge occur rapidly in response to snowmelt, while the soils remain frozen, via preferential flow through air-filled macropores.
