fw.1.3 River processes - erosion, transportation and deposition
Content
Geographic inquiry and concept(s)
How physical processes influence drainage basin systems and landforms
Geographic knowledge and understanding
River processes of erosion, transportation and deposition and spatial and temporal factors influencing their operation, including channel characteristics and seasonality
Case study or detailed examples
Neither required by the syllabus
Aims of this lesson
To have knowledge and understanding of the river processes of erosion, transportation and deposition, specifically:
Erosion - attrition, hydraulic action, solution, abrasion and vertical erosion
Transportation - suspension, dissolved load, saltation and traction
The Hjulström Curve and how it links erosion, transportation and deposition
To have knowledge and understanding of the spatial and temporal factors associated with river processes:
Channel characteristics - The inside of a meander vs. the outside
Seasonality - summer meltwater from glacial environments / seasonal differences in deltas
