Multiple timescales of streambed flux variability in two perennial mountain‐front streams

Multiple timescales of streambed flux variability in two perennial mountain‐front streams

Streambed fluxes are highly variable through time and space, having a range implications for stream‐aquifer processes. This study investigated streambed fluxes over a 3‐year study period to characterize short‐ and long‐term variations and related implications for seepage recharge and hyporheic excha...

Zusammenfassung:Streambed fluxes are highly variable through time and space, having a range implications for stream‐aquifer processes. This study investigated streambed fluxes over a 3‐year study period to characterize short‐ and long‐term variations and related implications for seepage recharge and hyporheic exchange. Time series of streambed fluxes were estimated through Darcy‐based methods using water level and temperature inputs from shallow (
