NP2.02 Scaling, multifractals and nonlinear variability in geophysics: Scaling, multifractals and nonlinear variability in hydrology (co-sponsored by HS)

Event Information

Most properties and fields related to hydrological processes, including cloud patterns, precipitation, degree of soil saturation and runoff production, subsurface porosity and soil permeability, are highly variable and intermittent over a wide range of physical scales. In contrast to conventional stochastic models, fractal and multifractal models are intrinsically capable of representing this fundamental irregularity feature through renormalization invariance properties and scaling exponents. This session is devoted to theoretical and operational scaling approaches for the characterization of hydrologic media and for the modeling of precipitation, surface water and groundwater processes. Contributions on floods that emphasize linkage to basic processes such as precipitation and runoff or deal with fundamental issues of scaling should be submitted to this session, whereas risk-oriented flood studies would be more apropriately submitted to NP2.04.
