The study analyzed how carbon is transported during rainfall in the Yangjuangou dam watershed in China's Loess Plateau. They found that wet and dry seasons had different carbon deposition levels, with small contributions to overall transportation. During heavy rainfall in August and September, carbon transportation peaked. Different rainfall intensities led to varying carbon loss processes, mainly through dissolved inorganic carbon. The watershed's carbon loss modulus in the rainy season was determined to be 1.89 kg per square kilometer per month, potentially reaching 2.70 kg per square kilometer per year.
