Abstract

The difference in the influencing pattern of extreme rainfall and artificial recharge events on hydrological processes remains elusive. To address this question, this study implemented a high-resolution synchronous monitoring program by utilizing stable hydrogen-oxygen and nitrogen-oxygen isotopes across multiple components, including river water, groundwater, soil water, and rainfall in a typical region of China. The results indicated a significant positive correlation between soil moisture and artificial recharge, soil moisture increased exclusively at depths of 100 cm and 120 cm during artificial recharge. The artificial recharge showed a “Down-Top” influencing pattern on soil hydrological process, i.e., the artificial recharge first increased the groundwater table and afterwards enhanced the soil moisture. A “Top-Down” pattern occurred in the influence of extreme rainfall on soil hydrological process, i.e., the extreme rainfall moved the water from top soil to down soil, and consequently raised the groundwater table. Rainfall and ecological water recharge also both lead to migration of nitrate nitrogen mainly in the upper and middle soil layers. Extreme heavy rainfall events cause a reduction of nitrate nitrogen content in the 0–120 cm soil layer of farmland by 32.29–160.90 mg·kg−1, and the nitrate nitrogen accumulation peak shifts from 40 to 60 cm to 80–100 cm. Ecological water recharge mainly affected the migration of nitrate nitrogen in the middle and lower soil layers of farmland. In addition, the influence of ecological water recharge on nitrate nitrogen migration also showed obvious seasonal differences, with summer > spring > winter. The results of this study would provide basis for understanding the water cycling under Climate change and human activities.
