Sea level rise could lead to shifting rivers
- "Sea-level rise due to climate change is poised to shift the way that rivers naturally chart their path to the shoreline... Periodically, a river will change its course to the sea, forming a new path through a process called river avulsion. River avulsions are a natural part of a river's life and are responsible for building new land and nourishing wetland ecosystems with water, nutrients, and sediment. However, river avulsions are also catastrophic natural hazards. They were responsible for some of the deadliest floods in human history, including the 1887 Yellow River floods and the 1931 China floods, which together claimed an estimated six million lives. On some rivers, like the Mississippi, engineers have built bypass channels and levees to counter the dangers of river avulsion." - Excerpt from California Institute of Technology
