“…Furthermore, the soil at the gentle slope has a smoother surface because of an erosion crust [74]. Higher rainfall intensities not only supply more direct rainfall water but also generate more runoff water and increase the flow depth, which can dissipate the energy of the raindrop, protect the seal from breakage and decrease infiltrability [75]. The hydraulic conductivity of the surface seal is typically much lower than that of the underlying soil layer, which limits water infiltrating capacity [73].…”

“…A more rapid decline in the hydraulic gradient under the intense rainfall events is a factor reducing the infiltrability observed between the storms of lower and higher intensities [67]. Furthermore, higher rainfall at steeper slopes caused higher flow velocities leading to less opportunity for water transmission into soil layers and the magnitude of surface runoff, and the recharge of soil are directly affected by the amount of water infiltrating the soil surface [75]. Therefore, greater rainfall intensities might reduce soil water recharge and increase surface flow [83].…”

Purple soil is widely distributed in the hilly areas of the Sichuan basin, southwest China, and is highly susceptible to water erosion. The triggering of this process is related to slope, rainfall intensity and surface cover. Therefore, this study assesses the effects of different simulated rainfall intensities with different slopes on hydrological and erosional processes in un-mulched and mulched purple soils. Results show that the sediment and water losses increased with an increase of rainfall intensity and slope steepness. Generally, the slope contribution (Sc) on water and sediment losses decreased with increasing rainfall intensity and slope steepness under both un-mulched and mulched soil. In un-mulched conditions, water losses were independent of slope steepness (Sc < 50%) during the highest rainfall intensity. However, in mulched soil, the higher contributions of slope (Sc) and rainfall (Rc) were found for water and sediment losses, respectively, i.e., >50%, except during the increase in slope steepness from 15 • to 25 • under the highest rainfall intensity (120 mm·h −1 ). The effectiveness of mulch was more pronounced in reducing sediment losses (81%-100%) compared with water losses (14%-100%). The conservation effectiveness of mulch both decreased and increased with slope steepness for water and sediment losses, respectively, under higher rainfall intensities. Water infiltration and recharge coefficient (RC) decreased with an increase of slope steepness, while with an increase in rainfall intensity, the water infiltration and RC were increased and decreased, respectively, in both un-mulched and mulched soil. On the other hand, mulched soil maintained a significantly (α = 0.05) higher infiltration capacity and RC compared to that of the un-mulched soil.

“…The results showed that these three empirical formulas were all simulated well in our experimental plot, but the Horton model had the best modelling result, with the determination coefficient ranging from 0.94 to 0.99, followed by the Kostiakov model, and the accuracy for the Philip model was the lowest. Liu et al came to the same conclusion using the runoff-on-out method [34]. Table 5.…”

Abstract:The characteristics of rainfall-runoff are important aspects of hydrological processes. In this study, rainfall-runoff processes and soil moisture dynamics at different soil depths and slope positions of grassland with two different row spacings (5 cm and 10 cm, respectively, referred to as R5 and R10) were analyzed, by means of a solution of rainfall simulation experiments. Bare land was also considered as a comparison. The results showed that the mechanism of runoff generation was mainly excess infiltration overland flow. The surface runoff amount of R5 plot was greater than that of R10, while the interflow amount of R10 was larger than that of R5 plot, although the differences of the subsurface runoff processes between plots R5 and R10 were little. The effects of rainfall intensity on the surface runoff were significant, but not obvious on the interflow and recession curve, which can be described as a simple exponential equation, with a fitting degree of up to 0.854-0.996. The response of soil moisture to rainfall and evapotranspiration was mainly in the 0-20 cm layer, and the response at the 40 cm layer to rainfall was slower and generally occurred after the rainfall stopped. The upper slope generally responded fastest to rainfall, OPEN ACCESSWater 2014, 6 2672 and the foot of the slope was the slowest. The results presented here could provide insights into understanding the surface and subsurface runoff processes and soil moisture dynamics for grasslands in semi-arid regions.

The purpose of this study is to evaluate the potential for infiltration in a study area -Rožnov pod Radhoštěm, the Czech Republic. The results are important for the future design of an artificial recharge structure as a method to store water underground in times of water surplus. A total of six measurements of infiltration were made using a double ring infiltrometer on selected prospective sites for the future application of artificial recharge. The results of infiltration tests were analysed based on the Philip`s model. The steady soil infiltration rates ranged from 28 cm•h -1 to 70.38 cm•h -1 and the cumulative soil infiltration ranged from 58 cm to 68 cm.
