Water level fluctuation induced variation of sulfamethazine biogeochemical behavior and expression of resistance genes in the hyporheic zone: A case study of Chaobai river, China
It is well known that the intensive biogeochemical activity in hyporheic zone of groundwater and antibiotic contaminated river water induced the pollution diffusion and variation of biogeochemical transformation. However, the complex interaction process caused by water level fluctuation is difficult to accurately depict on a larger, catchment scale. Therefore, a loosely coupled HYDRUS-3D/GMS was e
