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.
River channel migration is the geomorphological process that involves the lateral migration of an alluvial river channel across its floodplain. This process is mainly driven by the combination of bank erosion of and point bar deposition over time. When referring to river channel migration, it is typically in reference to meandering streams.
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 ...
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 ...
Meander cutoff. A meander cutoff is a natural form of a cutting or cut in a river occurs when a pronounced meander (hook) in a river is breached by a flow that connects the two closest parts of the hook to form a new channel, a full loop. The steeper drop in gradient (slope) causes the river flow gradually to abandon the meander which will silt ...
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 ...
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.
The Genesee River (/ ˌdʒɛnɪˈsiː / JEN-iss-EE) is a tributary of Lake Ontario flowing northward through the Twin Tiers of Pennsylvania and New York in the United States. The river contains several waterfalls in New York at Letchworth State Park and Rochester. The river was historically used as a border between the lands of the Seneca to ...
