Alluvial river-channel motion and patterns
Alluvial river planforms tell us about the processes of channel change that they undergo.
The Fluvial System
Base level
Base level is the lowest elevation to which a river flows, and dictates the lowest elevation to which it can erode.
Bedrock and alluvial rivers; detachment- and transport-limited evolution
Rivers may be broadly classified into two endmember types: bedrock rivers, whose beds and banks are made of solid rock, and alluvial rivers, whose beds and b...
Hack’s Law, channel concavity, the steepness index, and river-profile analysis
We can decribe river and drainage basin geometry in a way that links to the stream-power law for bedrock incision.
Bedrock rivers and detachment-limited erosion
Bedrock rivers, and rivers with cohesive beds, evolve via detachment-limited erosion.
Introduction to the Fluvial System
The fluvial system comrpises all parts of the landscape impacted by water flow across the surface. In includes headwaters streams, river channels, valleys, t...
Streamflow and frequency, self-formed channels, and geomorphically effective discharge
Streamflow statistics and river-channel form are closely linked.
Lane’s Balance and the graded river (transport-limited): impacts of water supply and sediment supply on river channels
The Graded River sets its slope such that it transports the same amount of sediment that it is supplied with the amount of water that is supplied; it is a st...
Sediment in rivers and modes of sediment transport
Sediment can move along the bed, in low suspension, or high in the flow.
The stream-power law and detachment-limited river long-profile evolution
Bedrock river evolution can be modeled to occur via transfer of potential energy form flowing water into mechanical energy breaking down the bedrock and kine...
