How soil erosion and runoff are related to land use, topography and annual precipitation: Insights from a meta-analysis of erosion plots in China

Jianlin Zhao et al.

Summary: The study found that land use in China significantly affects soil loss and runoff, with lower rates on land covered by grass and trees compared to cropland. Slope gradient and slope length impact soil loss and runoff rates on cropland, while having no significant effect on plots with permanent vegetation cover. Runoff rates consistently increase with mean annual precipitation.

Sediment connectivity of small watershed affected by gully development and vegetation restoration on the loess plateau

Chengshu Wang et al.

Summary: The effects of gully development and vegetation restoration on sediment connectivity were investigated in a small watershed in the Loess Plateau. The study found that sediment connectivity decreased significantly due to rapid vegetation restoration. Additionally, gully development promoted sediment connectivity while vegetation restoration inhibited it.

Sediment connectivity concepts and approaches

Saeed Najafi et al.

Summary: In recent years, the concept of sediment connectivity has emerged in sediment management, describing the transfer of sediment between different landscape sections. There is structural and functional sediment connectivity, with disagreement and confusion remaining about conceptual and methodological approaches. More process-based studies are needed to achieve a comprehensive understanding of sediment yield and related processes.

Temporal variation in soil erodibility indices for five typical land use types on the Loess Plateau of China

Hao Wang et al.

Summary: Seasonal variations in soil erodibility indices were detected in different land use types on the Loess Plateau, with soil cohesion, saturated conductivity, drop impact, soil aggregate size, penetration resistance, and erodibility index generally increasing, while erodibility K factor decreasing. These changes were attributed to variations in biological soil crust thickness, plant litter density, root mass density, soil organic matter content, and soil bulk density over the course of one growing season.

Effectiveness of typical plant communities in controlling runoff and soil erosion on steep gully slopes on the Loess Plateau of China

Pingzong Zhu et al.

Summary: Vegetation restoration is recognized as an effective measure in controlling runoff and soil erosion. This study quantified the effectiveness of vegetation restoration on steep gully slopes of the Loess Plateau, China, showing that shrub communities are better at reducing erosion, while grass communities (especially with tap root systems) are better at maintaining runoff. Relationships between runoff and erosion under different plant communities can be well simulated by power functions.

Analysis of sediment accessibility and availability concepts based on sediment connectivity throughout a watershed

Saeed Najafi et al.

Summary: The study investigates sediment connectivity based on structural and functional aspects, showing that high structural connectivity does not necessarily lead to high sediment transportation. Structural connectivity reflects the potential for sediment transfer between specific source and sink areas, while functional connectivity occurs where soil erosion processes are actively eroding sediment.

Spatial-temporal assessment of water and sediment connectivity through a modified connectivity index in a subtropical mountainous catchment

Franciele Zanandrea et al.

Summary: By introducing precipitation and surface runoff characteristics as functional components into the connectivity index, a hydrosedimentological connectivity index (IHC) was proposed to evaluate the space-time variation of water and sediment connectivity in a subtropical catchment. The IHC proved to be a useful tool for identifying sediment transfer and deposition locations in catchments with limited data, providing a satisfactory representation of sediment transfer patterns and showing positive correlations with catchment flow values.

Quantifying sediment connectivity: Moving toward a holistic assessment through a mixed methods approach

Mike Turley et al.

Summary: The study evaluated various connectivity indices and discussed their role in providing a more comprehensive estimation of connectivity within the Tahoma Creek Watershed. It found that as the river channel progresses downstream, a significant transition occurs where the valley bottom abruptly widens, marking the decoupling of hillslopes from the active channel. Factors such as vegetation, topographic characteristics, and network structure were identified as important in high-gradient glacio-volcanic landscapes.

Effect of rainfall intensity and duration on soil erosion on slopes with different microrelief patterns

Longshan Zhao et al.

Summary: The study examined how rainfall intensity and duration impact the effectiveness of tillage-induced surface microrelief (TSM) in controlling soil erosion. Results showed that both depressions and mounds (DM) and troughs and ridges (TR) of TSM delayed runoff initiation and reduced runoff and sediment benefits (RRB and SRB) decreased with increasing rainfall intensity, duration, and slope. However, DM and TR were effective at controlling soil loss when rainfall intensity was below 90 mm/h and duration was shorter than 60 min. In high-intensity or long-duration rainfall, sediment from DM and TR was higher than that from smooth surfaces (SS), highlighting the need for further assessment of TSM effectiveness in reducing soil erosion under varying climatic conditions.

Three decades of ephemeral gully erosion studies

Gang Liu et al.

Summary: The review identified key research areas in ephemeral gully (EG) erosion, including processes, factors, methodology, models, and detrimental effects. It highlighted the global consistency in the definition of EG. Urgency was emphasized in defining critical morphological values under different conditions for accurate mapping and modeling of EG development.
