CO2 delivered to streams through groundwater discharge

Spatial gradient from hillslope to riparian zone representing changes in hydrology, geochemistry, and proximity to stream

Peaks and troughs in groundwater level time series representing maximum and minimum water levels

Water movement and chemistry dynamics that maintain fen ecosystems and support specialized plant communities

Water-related environmental factors including humidity, rainfall, snow cover, and soil moisture that affect disease transmission and host physiology

The maximum rate at which water can enter soil under specified conditions

Water storage transfer between seasons, particularly winter snow storage contributing to summer flows

Lateral movement of snowmelt downgradient through soil zone toward topographic convergent zones to form streams

More young water released from storage during wet periods than during dry periods
