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] Rivers must flow to lower altitudes due to gravity. [3] The bed of a river is typically within a river valley between hills or mountains.
These characteristics are a result of the dynamic river system, where larger grains are transported during high energy flood events and then gradually die down, depositing smaller material with time (Batty 2006). Deposits for meandering rivers are generally homogeneous and laterally extensive unlike the more heterogeneous braided river deposits ...
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 ...
Johnson Creek is a 25-mile (40 km) tributary of the Willamette River in the Portland metropolitan area of the U.S. state of Oregon.Part of the drainage basin of the Columbia River, its catchment consists of 54 square miles (140 km 2) of mostly urban land occupied by about 180,000 people as of 2012.
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.
Rivers such as the Congo, Africa’s second largest river, the Yangtze, which weaves through China, and South America’s Plata saw significant declines, said Dongmei Feng, the study’s lead ...
Atmospheric rivers could become stronger and have more impacts along the West Coast due to climate change. A new study shows how water rise and increased rainfall could impact residents who face ...
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.
