TLDR
In this article, the authors describe laboratory testing of 148 samples collected from Southern Alberta for erosion by wash and splash, and the significance of other soil properties, such as organic carbon and clay content is variable, depending on the interrelationships among aggregate stability, organic content, and clays.Abstract:
This paper describes laboratory testing of 148 samples collected from Southern Alberta for erosion by wash and splash. Rainfall intensity was held constant during these tests. Soil aggregation was the most significant variable explaining soil loss. The significance of other soil properties, such as organic carbon and clay content is variable, depending on the interrelationships among aggregate stability, organic content, and clay content of particular soils. Variations in erodibility of the major soils examined are explained by the resistance of aggregates to compaction and dispersion. Splash detachment and wash transport are the dominant erosion mechanisms in inter-rill areas.read more

Soil erodibility and processes of water erosion on hillslope
TL;DR: In this article, the authors focus on experimental research on rill and interrill erosion using simulated rainfall and recently developed techniques that provide data at appropriate temporal and spatial scales, essential for event-based soil erosion prediction.

TL;DR: In this article, the authors used equal-area quadratic splines and regression rules to predict clay, silt, fine sand, and coarse sand content at six standard soil depths of GlobalSoilMap project (0-5, 5-15, 15-30, 30-60, 60-100, and 100-200 cm).

TL;DR: A review of the scientific literature published in peer-reviewed international journals (ISI) over the last decades on splash erosion research sheds light on the current scientific knowledge on this topic and highlights the research gaps and unanswered questions in our understanding of soil erosion processes due to splash as mentioned in this paper.

The role of land use-land cover on runoff generation and sediment yield at a microplot scale, in a small Mediterranean catchment
TL;DR: In this paper, replied runoff-erosion microplots (less than 1m2) have been set up in eleven environments representative of the land uses in the catchment, in order to measure and evaluate their rates after each rainfall event, during dry and wet soil conditions (summer and winter, respectively).

A Direct Method of Aggregate Analysis of Soils and a Study of the Physical Nature of Erosion Losses1
TL;DR: The physical nature of the erosion process was studied on carefully controlled field plats of Cecil clay located on several slopes, and losses from this strongly aggregated soil occurred primarily in the form of water stable aggregates.

Rainfall energy and its relationship to soil loss
W. H. Wischmeier,Dwight D. Smith +1 more
TL;DR: In this article, a relatively simple procedure is presented for computation of kinetic energy of a rainstorm from information on a recording-raingage chart, and an equation is developed describing rainfall energy as a function of rainfall intensity.

TL;DR: The applicability of such results to conditions of natural rainfall has been thrown in doubt as discussed by the authors, and the results have been found to be affected by the drop-size and velocity of the artificial rains applied.

Microaggregates in soils1
A. P. Edwards,J. M. Bremner +1 more
TL;DR: In this paper, a theory is proposed depicting microaggregate formation as a solid-phase reaction involving linkage of electrically neutral clay mineral and organic matter particles by polyvalent metals on exchange sites, and micro aggregates disruption by sonic vibration as a reversal of this reaction.
