MinuteEarth: de ce râurile au delte

Where rivers meet the ocean, coastlines tend to bend either inward or outward, creating estuaries and deltas. But how do they get those shapes?

A huge thank-you to the following organizations, all working toward sustainable deltas, for sponsoring this video: the Belmont Forum, the Sustainable Deltas Initiative, the National Center for Earth-Surface Dynamics, the St Anthony Falls Laboratory of the University of Minnesota, and the DELTAS project. These organizations study deltas around the world, in particular how they’re threatened by human activities such as building dams, channelizing rivers, and climate change-induced sea-level rise. If we don’t pay attention, we might lose the landform that allowed us to become civilized in the first place.
