Groundwater is critical to life in
California (and much of the world)
and current use is unsustainable
By SGMA and by necessity
groundwater management must
change
Why Groundwater?
Over 96% of liquid fresh water is
groundwater
Overdraft ~1-2 million AF/yr
Science can help improve
management practices
Groundwater Management Grand Challenge
Precipitation Comes in Pulses
How to connect short term
extreme events to long
term groundwater storage?

“Seeing” Underground
Where is there suitable subsurface for recharge?
Land Use:
Which orchards? Which parts of the orchard?
Management:
How much water can be applied?
Will it keep the roots wet?
Will it transport/dissolve contaminants?
Etc.
