英文摘要	Recharge between a river and shallow aquifer in a floodplain involves critical hydrological processes for the whole ecological environment, which often exhibits heterogeneity because of seasonality and geological complexity. In this study, electrical resistivity tomography (ERT) was used to analyze the temporal and spatial variations in the recharge characteristics of a floodplain under a variety of climatic and geological conditions. Two sets of ERT tests (in the dry season and wet season) were conducted. Each test included four ERT lines to capture the dynamic electrical resistivity distribution associated with season-driven, river and shallow groundwater interactions along a stretch of the Yellow River (adjacent to the floodplain) in China. The findings indicate that this floodplain is composed of three distinct hydrogeological units. Additionally, ERT images taken during the wet season demonstrate that river water recharges the shallow aquifer and then flows toward the middle aquifer via several seepage channels. Based on time-lapse ERT images, different recharge characteristics are identified in the low and high floodplain. In the low floodplain, both the Yellow River and the vadose zone are preferential shallow groundwater recharge zones. In the high floodplain plain, only the vadose zone is a preferential shallow groundwater recharge zone. Resistivity mapping can provide valuable information about the recharge between surface-water bodies and shallow aquifers. This is particularly useful when combined with water level data, and resistivity distribution with depth can also be used to characterize the stratigraphic structure of the floodplain.
