Floodplains recharge groundwater when rivers spill gently
When a river rises onto its floodplain without raging through a canyon, water soaks into alluvial soils and percolates toward aquifers that wells and wetlands later tap.
Slowed floodwater also drops fertile silt that rebuilds soil for meadows and riparian woods. Natural levees and backswamps mosaic the plain into many micro-habitats.
A spill can be a gift if the landscape is allowed to receive it. Floodplain ecology links rivers-lakes pulse to underground storage — and to wildlife that needs wet seasons written on the land.
