Water Always Wins

Humans have lengthy tried to wrangle water. We’ve straightened once-meandering rivers for transport functions. We’ve constructed levees alongside rivers and lakes to guard individuals from flooding. We’ve erected complete cities on drained and filled-in wetlands. We’ve constructed dams on rivers to hoard water for later use.
“Water seems malleable, cooperative, willing to flow where we direct it,” environmental journalist Erica Gies writes in Water Always Wins. But it’s not, she argues.
Levees, which slender channels inflicting water to circulation increased and sooner, almost at all times break. Cities on former wetlands flood usually — typically catastrophically. Dams starve downstream environs of sediment wanted to guard coastal areas in opposition to rising seas. Straightened streams circulation sooner than meandering ones, scouring away riverbed ecosystems and giving water much less time to seep downward and replenish groundwater provides.
In addition to laying out this harm finished by supposed water management, Gies takes readers on a hopeful world tour of options to those woes. Along the best way, she introduces “water detectives”— scientists, engineers, city planners and plenty of others who, as an alternative of making an attempt to regulate water, ask: What does water need?

These water detectives have discovered methods to provide the slippery substance the time and house it must trickle underground. Around Seattle’s Thornton Creek, for example, reclaimed land now permits for normal flooding, which has rejuvenated depleted riverbed habitat and created an city oasis. In California’s Central Valley, scientists need to discover methods to shunt unpolluted stormwater into historic, sediment-filled subsurface canyons that make ultimate aquifers. Feeding groundwater provides will in flip nourish rivers from under, serving to to keep up water ranges and ecosystems.
While some individuals are exploring new methods to handle water, others are leaning on ancestral information. Without the usage of hydrologic mapping instruments, Indigenous peoples of the Andes have an in depth understanding of the plumbing that hyperlinks floor waters with underground storage. Researchers in Peru are actually finding out Indigenous strategies of water storage, which don’t require dams, in hopes of making certain a gentle circulation of water to Lima — Peru’s populous capital that’s periodically stricken by water shortage. These research could assist persuade these steeped in concrete-centric options to attempt one thing new. “Decision makers come from a culture of concrete,” Gies writes, wherein dams, pipes and desalination vegetation are normal.Understanding work with, not in opposition to, water will assist humankind climate this age of drought and deluge that’s being exacerbated by local weather change. Controlling water, Gies convincingly argues, is an phantasm. Instead, we should study to dwell inside our water means as a result of water will undoubtedly win.
