Özet
This study was performed by the reevaluation of historical Universal Soil Loss Equation using field experiment data that was obtained between 1978 and 1995 in Tokat, Turkey. In the study area, the annual average rainfall was 452 mm and about 50% of erosive rainfall events were less than 10 mm. The duration of average erosive rainfall event was 6 h and the average event intensity was 3.83 mm h-1. The average erosive rainfall time in daylight (06:00-18:00), night (18:00-06:00) and mix rainfall conditions were 223.1 and 191.6, 450.2 min, respectively. The maximum rainfall amount, event intensity, storm erosivity, the maximum intensity of 10 min (IM10), the maximum intensity of 15 min (IM15), the maximum intensity of 30 min (IM30) were mostly occurred in daylight erosive rainfalls. But the maximum soil loss and runoff produced by night erosive rainfall. This situation was attributed to the short-term effect on soil erodibility of day and night temperature differences in spring which is rainfall erosivity is high for the region. Higher correlation is observed between soil loss and IM10 compared to IM30. USLE R-factor showed a good correlation with Modified Fournier Index (MFI) for the region. The Mann-Kendal and Theil-Sen Slope estimator statistics to detect the direction and magnitude of an available monotonic trend in some erosivity parameters as well as soil loss and runoff. Trend analysis showed monotonic decreasing of all rainfall physical properties, soil loss and runoff.
