Surface water–groundwater interactions

Mission: advance the fundamental understanding of hyporheic flow and contribute to the advanced understanding of surface water–groundwater interactions

Hyporheic flow

Hyporheic zone refers to the region of sediment bed between surface stream and groundwater, where water, nutrients, and contaminants are continuously being exchanged. The exchange between surface and subsurface water supplies nutrients and oxygen to subsurface microbes and thus controls the biogeochemical cycles and biodiversity of stream bed, as well as its resilience against disturbances. We investigate fundamental mechanisms governing the fate and transport of solutes in hyporheic zones. Also, we extend the findings to better understand surface water-groundwater interactions.
