Fingerprint Basics
Run DSM2-hydro
This module will provide Delta-wide flows, stage, and
velocities.
Run DSM2-qual
This module will estimate:
Volumetric fingerprints – fixed and equivalent boundary
source concentrations
Constituent fingerprints – actual boundary source
concentrations
All constituent sources are modeled independently.

Future work
• Validation methodology for fingerprints has
been explored by analyzing EC concentrations
versus grab sample mineral data such as
chloride, sulfate, bicarbonate, and bromide.
(Paul Hutton, Ph.D., MWD) These anion
concentrations have shown a strong
relationship to Delta source waters.
• Modeling more constituents in DSM2 will
provide data to further analyze source mixing
and indicate actions needed to improve DSM2.

Fingerprint Conclusions
• Extending the timeline :
– The historical fingerprint is continually being updated
(1991 to current).
– We also will be modeling further back in time (perhaps
to 1976).
• Useful information from fingerprints :
– The current historical fingerprints can provide
information such as relative source water to seasonal
trends and water year type.
– The data, however, is in need of further analysis.

…Fingerprint Conclusions
• Fingerprinting sources upstream :
– Fingerprinting sources upstream of major boundary
inflows may prove to be a valuable management tool.
– still in development
• Further development :
– fingerprint validation methodology
– modeling of more constituents
– The above combined with a future DSM2 recalibration
process will lead to a more accurate depiction of
source waters in the Sacramento-San Joaquin Delta.
