Brief Communication: Investigating the invisible subsurface stormflow process through a thorough and systematic study across sites and scales Open
Subsurface stormflow (SSF) is one of the least studied and therefore least understood runoff generation processes because detecting and quantifying SSF is extremely challenging. However, the impact of SSF on streamflow dynamics and water q…
