Landforms produced by erosion and deposition Understand the relationship between landforms and the processes that have created them, especially the interplay between erosion and deposition.
Understand the evolution of fluvial or water-formed landscapes as the outcome of dynamic processes such as slope erosion, stream erosion and deposition.
Understand that the principle underlying the relationship between velocity and particle size (as shown by the Hjulström diagram) is the basis for understanding erosion, transportation and deposition.
Understand the formation of waterfalls and rapids, meanders and associated landforms, flood plains, braided channels, levees and deltas.
Be aware that changes in base level can affect erosion and deposition in the basin, and understand the concepts of rejuvenation, knickpoints and terraces.
Natural and human-induced hazards Be aware of the processes of flooding (flash and lag responses) and the effect of humans on fluvial processes, including the effect of urbanization on stream flow and percolation; urbanization and forestry on both flooding and stream siltation and the impacts of agriculture, mining and industry. Flooding is a natural phenomenon that can be exacerbated by the effects of human activity. Understand that changes in land use can affect flood recurrence intervals. Study hazards in terms of risk vulnerability and response.
