Story summary

Rivers are more than just flowing water; they are dynamic ecosystems. Researchers at the University of California, Santa Barbara, discovered that when bank erosion outstrips sediment deposition, rivers split into multiple channels. Their analysis of 36 years of satellite data reveals how single-threaded rivers maintain stability, while multi-threaded ones expand and diverge, offering crucial insights for restoration efforts.
