Fluvial systems/river structure

Geomorphology

landform evolution processes; an understanding of how landscapes are shaped

fluvial processes

flow processes and sediment and solute transport to form landscapes

fluvial geomorphology

the study of the forms, processes, materials, and evolution of rivers

river structure

catchment, landscape unit, reach, geomorphic unit, hydraulic unit

catchment

a single fluvial system that is linked internally by a network channels

landscape units

areas of similar topography that have a characteristic pattern of landforms

Geomorphic unit

landform-scale features reflecting formative process that determine river structure and function

hydraulic unit

a spatially distinct patch of relatively homogeneous surface flow and substance character

segment

an alternating (repeating) sequence of reaches

knickpoint/head cut

when a river makes ground cave in on itself
