A modification of a rainfall simulation procedure at runoff plots for the study of erosion is suggested. It is based on the (1) physically substantiated erosion parameter of simulated rainfall A , (2) the new erosion index for natural rains AI derived from the erosion parameter A , and (3...
At the same time as runoff sampling, the amount of rainfall was measured at 10-min intervals using a recording rain gage which was installed at the meteorological station near the plots. Table 1. Number of plots for each hillslope, total sample volumes, and mean runoff, soil loss and ...

Introduction Agriculture is the primary source of food for livelihoods in Sub-Saharan Africa (SSA) due to its vital role in dimensions that embody food security [1,2]. Despite this, the sector ...
This study aimed to evaluate the suitability of literature parameter values for the Green–Ampt infiltration model to be used in hydrodynamic rainfall–runoff simulations. The outcome of this study supports to decide which literature values should be taken if observed data for model calibration is not...
evaporation lowers the water temperature because of the latent heat flux15. SSS can serve as a proxy for freshwater fluxes integrating the variability of flux processes, and their spatially and temporal inhomogeneity, e.g., of turbulent latent fluxes16. However, the small-scale processes on the ...

gradients ranged from 0 to 40° by adjusting the filling material height at the front and rear of soil flume. There was a groove and outlet at the front end of flume to collect the runoff and sediment from the slope. The device of the rainfall simulator and soil flumes are shown in ...

Plot-based rainfall simulation tended to yield higher (but in some instances, lower) estimates of Ksat than were derived from natural rainfall on the same plots (see Table 9 in Lusby & Lichty, 1983). In other words, the results were variable and inconsistent. For the catchment runoff, ...
The rainfall simulator consists of a controller, gauges, pumps, water pipes and sprinklers, as well as other components. The type of sprinklers is rotary downjet Overland flow against vegetation type and coverage The shrub-grass communities were more effective to delay the overland flow generation...
