In the chronically overpumped San Joaquin Valley, groundwater recharge can’t happen fast enough. And researchers at Stanford University have found underground highways that could put recharge into the fast lane.
In a new paper released today, scientists show that airborne electromagnetic (AEM) surveys flown with helicopters can locate ancient underground passageways, called paleochannels. Scientists and water managers alike say this finding could have significant impacts on how water is recharged in the valley.
