2021年4月12日 · Understanding delta formation in an environment like the Mississippi River Delta, that is experiencing both erosion and accretion, is important because the U.S. Gulf Coast is experiencing some of the highest levels of global sea level rise: between 9 to 12 mm per year, which is three-to-four times the global average. The Investigation

2020年7月28日 · Scientists say the 560 kilometers (350 miles) of levees prevent the river from replenishing the delta with new sediment, causing parts of the land to sink further below sea level. This, and the increase in flooding, have left communities extremely vulnerable to damage from hurricanes, such as Hurricane Katrina in 2005.

2021年1月3日 · The Niger River begins in the Guinea Highlands in southeastern Guinea, flowing north and in a northeasterly direction into Mali to the Inland Niger Delta. The river then turns east and then curves southeast to Niger, the border of Benin and through Nigeria to the Niger Delta and ending into the Gulf of Guinea in the Atlantic Ocean.

2020年12月27日 · Rising in northern Minnesota, the Big Brown picks up nutrient-rich sediment along its 2,300 mile-long journey south and deposits the slough into Louisiana’s wetlands. But before it enters the boot of Louisiana, it feels the tug of the Atchafalaya River, a distributary on its right bank. By the 1940s, one-third of the great river had been ...
