The study investigates soil erosion rates in the Serayu Watershed using the Revised Universal Soil Loss Equation (RUSLE) and analyzes the correlation between average daily rainfall and soil loss from 2003 to 2023. Data on annual average daily rainfall and soil loss rates were obtained from publicly accessible sources, including satellite imagery and government datasets. The analysis revealed a significant increase in average daily rainfall in the years 2010, 2011, and 2016, which corresponded to notable spikes in soil loss rates. The peak soil loss occurred in 2016, with a value of 186 tons/ha/year, closely followed by significant losses in 2010 and 2011. The findings demonstrate a strong correlation between increased rainfall intensity and higher soil erosion rates, emphasizing the vulnerability of the watershed to climate variability. These results highlight the need for adaptive soil conservation strategies and improved watershed management practices to mitigate the adverse effects of increased rainfall on soil erosion. This study provides valuable insights for policymakers and land managers in developing effective erosion control measures in the Serayu Watershed.
