Decoding impacts of slope length on sheet erosion based on calculus method

This data was conducted using indoor artificial rainfall. A single soil type (loessial soil) was used throughout the experiment, with experimental treatments comprising five slope lengths (0.4, 0.8, 1.2, 1.6, and 2.0 m), five rainfall intensities (0.800, 1.040, 1.700, 2.475, and 2.835 mm min-1), and five slope gradients (0.1763, 0.2679, 0.3640, 0.4663, and 0.5774). Each combination of slope length, rainfall intensity, and slope gradient was replicated twice, resulting in a total of 250 simulated rainfall events, with mean values from two replicates employed for statistical analysis. The last six stable values of each rainfall event were selected as replicates for data analysis.
