Using a suite of complementary ground...
Briggs, Martin; Wang, Cheng-Hui; Day-Lewis, Frederick; Williams, Kenneth H.; Dong, Wenming; Lane, John Residence time controls on the fate of nitrogen in flow‐through lakebed sediments
For many glacial lakes with highly permeable sediments, water exchange rates control hydrologic residence times within the sediment‐water interface (SWI) and the removal of reactive compounds such as nitrate, a common pollutant in lakes and groundwater. Here we conducted a series of focused tracer injection experiments in the upper 20 cm of...

Spatially preferential flow processes occur at nested scales at the sediment-water interface (SWI), due in part to sediment heterogeneities, which may be enhanced in flashy urban streams with heavy road sand influence.
