Landscape evolution models (LEMs) are widely used to calculate changes in Earth\u2019s topography due to erosion, but the model parameters are notoriously difficult to constrain.
\nIn order to gain a better understanding and find the best-fit parameters, Gregory Ruetenik and his collegues from Surface Processes and Palaeoclimate team compared modelled erosion rates against a global compilation of long-term erosion rate data derived from cosmogenic 10<\/sup>Be.<\/p>\n

This novel method demonstrates that LEMs, used in tandem with data, can inform us about the behaviour of real landscapes. They looked at the global variability in parameters and found a correlation between precipitation and coefficients for optimized models, where areas with higher precipitation corresponded to a higher erodibility. However, despite this general positive relationship, they also found an anomalously high erodibility in semi-arid environments. Landscapes are most easily eroded at both extremes of precipitation (wet and dry).<\/p>\n

“We also saw unexpected correlations between rock-type and landscape erodibility, indicating that rock type alone cannot always be used to determine the erodibility of a landscape; other factors (such as the number of fractures in the rock) may be equally or more important than rock type,” adds G. Ruetenik.<\/p>\n
