![]() ![]() They made a multi-billion-euro investment to draw levees back.” “The Europeans in the 1990s started doing this. “We are behind the curve on this,” Pinter told CNN. Nicholas Pinter, a researcher and professor of applied geosciences at the University of California at Davis, acknowledged managed retreat is a tall task but noted other countries are doing it. It means entire communities would need to relocate the process is known as managed retreat. Those aquifers are a vital source of water for drinking, bathing and agriculture across California’s Central Valley, and they are running dry.īut giving rivers more space to flood has a catch. Many climate experts agree – using levees to prevent floods during the wet season means less water is available to seep into underground aquifers. “That will allow us to capture more of these flood flows, store it underground in these aquifers, and then use those ground water resources when we need them in dry years.” “We need new thinking, we need to operate that infrastructure differently, we need to change some of the characteristics of that infrastructure,” Gleick said. Levees have effectively protected communities in the past, Gleick said, but they’re not designed for the climate-change challenges of today. “Instead of thinking we can control all floods, we have to learn to live with them.” ![]() “We have to let our rivers flow differently, and let the rivers flood a little more and recharge our groundwater in wet seasons,” Peter Gleick, a climate scientist and co-founder of the Pacific Institute in Oakland, told CNN. ![]()
