SMODERP2D-Sheet and Rill Runoff Routine Validation at Three Scale Levels

Petr Kavka et al.

Summary: Water erosion is the main cause of soil degradation in agricultural areas, with rill erosion contributing significantly to the erosion rate. Identifying areas prone to rill erosion is crucial for soil protection. Research on rainfall-runoff processes and sediment transport often involves observing these processes at multiple scales and mathematical descriptions.

Evolution and spatio-temporal characteristics of slope erosion due to rainfall in Southwest China

Ganglie Yuan et al.

Summary: This study investigates the impact of heavy rainfall on slope erosion by conducting an in situ model test of a decomposed granite slope. The results show that an increase in rainfall duration leads to an increase in rill density on the slope surface and a higher erosion rate. Additionally, a decreasing trend of erosion rate is observed from the bottom to the top of the slope and from the shallow to the deep part of the slope.

Runoff scouring experimental study of rill erosion of spoil tips

Yongcai Lou et al.

Summary: The study investigated rill erosion on spoil tip slopes and the mechanisms of rill erosion. Inflow rate was found to be the most important factor affecting soil erosion. Rill development went through formation, development, and adjustment stages. The average rill depth was identified as the best indicator for evaluating rill erosion. Reynolds number and flow shear stress were identified as the best parameters for predicting and describing rill erosion mechanism.

Comparison of Critical Shear Stress of Rill Erosion Estimated from Two Methods

Ren Geng et al.

Summary: This study evaluates the reliability of different methods for determining the critical shear stress of rill erosion and explores its relationship with erodibility and influencing factors. The results show differences in the critical shear stress obtained from different methods and no significant relationship with erodibility. This has important implications for understanding the mechanism of rill erosion.

Quantifying the contributions of soil surface microtopography and sediment concentration to rill erosion

Jian Luo et al.

Summary: The study found that with the increase in upslope filling area, the minimum values of soil surface elevation also increased. As rill erosion developed, the soil surface microtopography tended to sharpen and the relative elevation changed greatly. Furthermore, runoff and soil loss gradually decreased with the increase in upslope filling area.

An Enhanced Flume Testing Procedure for the Study of Rill Erosion

Vinicius Naves de Oliveira et al.

Summary: This study presents the development and verification of an improved and cost-effective flume apparatus and corresponding testing methodology. The equipment and testing methodology produced erosion curves with repeatability that were superior with respect to their initial linear and transition portions. Recommendations are made regarding the adequate interpretation of the testing data and the selection of the ideal elapsed time for soil loss analysis.

Inferring Sediment Transport Capacity from Soil Microtopography Changes on a Laboratory Hillslope

Sayjro Nouwakpo et al.

Summary: This paper tests a methodology to infer the exceedance of transport capacity by concentrated flow from changes to soil surface microtopography and applies it to experimental data on soil erosion and sediment transport processes. Results suggest a significant impact of subsurface hydrology on erosion patterns and a dependence of transport capacity on subsurface hydrology conditions.
