Conceptualizing relationships among hyporheic exchange, storage, and water age: data represented in published figures

Hyporheic exchange is a key driver of ecosystem processes in streams, yet
stream ecologists often fail to leverage detailed conceptual models
developed by engineers and hydrologists describing the relationship
between water storage, water balance, and water age (time elapsed
since a conceptual parcel of water entered the hyporheic zone) in
hyporheic zones.  In a companion paper (G.C. Poole et al.
Hyporheic Hydraulic Geometry: Conceptualizing relationships among
hyporheic exchange, storage, and water age, published in PLoS ONE;
doi:10.1371/journal.pone.0262080), we provide visualizations of these
relationships in an effort to allow non-hydrologists to grasp four primary
concepts along with associated research and management implications: 1)
the rate of hyporheic exchange, size of the hyporheic zone, and hyporheic
water age are inexorably linked; 2) such linkages can be leveraged to
build understanding of hyporheic processes; 3) the age distribution of
hyporheic water and hyporheic discharge is heavily skewed toward young
water ages -- at any temporal scale of observation (minutes, hours, days,
or months) older hyporheic water is rare relative to younger water; 4) the
age distribution of water discharged from any hyporheic zone is not the
same as the age distribution of water stored within that hyporheic zone.
The data set presented here represents the numerical values represented by
the figures published in the companion paper.
