  Information - NP3.07 Scale, Scaling, and Nonlinearity in the Earth's Surface, Soil and Solid Earth (co-listed in GMPV, SSS & TS)

Event Information
In the broad area of soil science, geology and solid earth geophysics, observed features and underlying phenomena repeat from one scale to another. Such non-linear dynamics yield hierarchical distributions, space-time fractals sets or fields, self-organized critical events. The mathematics and physics involved appear to provide a robust yet simple way to describe these phenomena over wide ranges of scale and represent a natural approach to characterize such systems. Modelling and statistical approaches (including wavelets) are then able to extrapolate the observed properties to larger or smaller scales, resolutions. Contributions involving wavelets, fractals or multifractals, self-organized criticality, scaling models and forecasting are welcome. Specific application areas include volcanoes, remote sensing, topography, pedology, landscape morphology, distribution of minerals, geogravity, geomagnetism, the Earth's interior.Selected papers from EGU 2005 and 2006 meetings have been published in NPG Journal vol. 14 in 2007. Actually an special issue is in process based on EGU 2007 contributions.
