Related to this is that we insist on farming flood plains, and then "protecting" them with levees.
Nature already has a perfectly good system to deal with excess rain. Rivers expand to fill flood plains to buffer the excess water. Unfortunately we've blocked nature from doing this by building levees and otherwise channelizing rivers.
We've "gotten away with it" in large part, but ultimately somewhere is going to flood as climate events get more extreme. We'd be better off choosing to let farm fields flood a little on semi-regular occasions than building levees to the point that flood stage raises even higher and it's a complete catastrophe when a levee breaches near a city or town.
- engineer_22 4y ago-> We'd be better off... I think it's not so simple. Flood plains are agriculturally very productive, close to a river it's near transportation and a source of fresh water. Famously, the 4 Cradles of Civilization developed along rivers. I dont think we can assume we can simply abandon the riparian zones and continue along for the better.
- lostapathy 4y agoHistorically, those cradles of civilization were exceedingly productive because some years the flood plains flooded, not in spite of it.
