Spatio‐Temporal Variability of Hyporheic Exchange Processes Across a Stream Network

Hydrological Processes, Volume 38, Issue 12, December 2024.
Hyporheic exchange processes (HEP) scale across stream networks, but only limited knowledge exists about the temporal variability of HEP over the hydrological year and across the stream network. Combining field‐based measurements with numerical modelling, our findings reveal that HEP exhibit high temporal variability throughout the hydrological year in
