Processes involved:
Landsliding occurs when the shear forces exceed soil/regolith strength; this generally occurs when soil/regolith strength is reduced by an increase in water.
Processes involved are:
Land characteristics affecting processes | Factors affected by land characteristics | Management factors that modify land characteristics | |
Vegetation | - leaf area, rooting depth perenniality - total leaf area and canopy type - root depth and mass |
| All aspects of the vegetation are affected by selection of species and control of biomass by practices such as cultivating clearing trafficking fertilising grazing trampling burning |
Climate | - seasonal rainfall/evapotranspiration regime |
| |
Geology | - perviousness of rock or unconsolidated sediments - wet strength of rock/regolith - angle of dip |
| |
Topography | - slope degree - microrelief and position in landscape |
| |
Soil | - topsoil permeability - presence of slowly permeable layer - cohesion of particles/aggregates including tendency to slake and disperse - depth - clay mineralogy |
| Compaction and soil disruption by stock and vehicles, and by cultivating, will affect profile permeability |
