Reversing Falls of Saint John River. A number of rivers are known to have reversed the direction of their flow, either permanently or temporarily, in response to geological activity, weather events, climate change, tides, or direct human intervention.
Coordinates: 45°15′37″N 66°05′24″W. The Reversing Falls in New Brunswick. The Reversing Falls are a series of rapids on the Saint John River located in Saint John, New Brunswick, Canada, where the river runs through a narrow gorge before emptying into the Bay of Fundy. The semidiurnal tides of the bay force the flow of water to ...
The Chicago River is a system of rivers and canals with a combined length of 156 miles (251 km) [ 1 ] that runs through the city of Chicago, including its center (the Chicago Loop). [ 2 ] Though not especially long, the river is notable because it is one of the reasons for Chicago's geographic importance: the related Chicago Portage is a link ...
The Mississippi River[ b ] is the primary river and second-longest river of the largest drainage basin in the United States. [ c ][ 15 ][ 16 ] From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for 2,340 miles (3,766 km) [ 16 ] to the Mississippi River Delta in the Gulf of Mexico.
A tributary, [1] or an affluent, [2] is a stream or river that flows into a larger stream (main stem or "parent"), river, or a lake. [3] A tributary does not flow directly into a sea or ocean. [4] Tributaries, and the main stem river into which they flow, drain the surrounding drainage basin of its surface water and groundwater, leading the ...
Rivers flow downhill, with their direction determined by gravity. [6] A common misconception holds that all or most rivers flow from North to South, but this is not true. [6] As rivers flow downstream, they eventually merge to form larger rivers. A river that feeds into another is a tributary, and the place they meet is a confluence. [4]
In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin. They are governed by the topography of land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land. Geomorphologists and hydrologists often view streams ...
The terms river morphology and its synonym stream morphology are used to describe the shapes of river channels and how they change in shape and direction over time. The morphology of a river channel is a function of a number of processes and environmental conditions, including the composition and erodibility of the bed and banks (e.g., sand, clay, bedrock); erosion comes from the power and ...
