Landscape Evolution Model
Landscape evolution models come in two basic flavors qualitative and quantitative that can be applied across a wide range of spatial and temporal scales.
Landscape evolution model. This chapter will. The process response and dynamic equilibrium models are more like darwin s picture of a self adjusting unscripted system. Landscape history following a defined cycle is more akin to early misinterpretations of evolution which assumed a script guiding life to higher development. flume is a good example of a physical model used extensively to understand channel form and process and there have been.
Probably the earliest conceptual model for landscape evolution was proposed by davis 1889 1899. A pre landslide stage a landslide stage and a post landslide stage. Only parameter values which differ for these stages are listed in the table. A the synthetic landscape evolution model consists of three stages.
Whereas the original model included four parameters we obtained a dimensionless form with a single parameter which quantifies the relative importance of the incision threshold. We non dimensionalized a commonly used model of landscape evolution that includes an incision threshold. The tops of hills are dominated by sediment transport mechanisms and other diffusion and weathering mechanisms that smooth the land surface while hillslopes give way to valleys where water runoff becomes concentrated enough to outpace the smoothing processes and incises into the land surface.
