Summary

The scaling issue remains one of the largest problems in soil science and hydrology. This book is a unique compendium of ideas, conceptual approaches, techniques, and methodologies for scaling soil physical properties. Scaling Methods in Soil Physics covers many methods of scaling that will be useful in helping scientists across a range of soil-related disciplines. The first single-source reference in this developing field, the text will help readers develop a greater understanding of how to interpret remote sensing data, delineate management zones in agricultural fields, and estimate water yield and geochemical fluxes in watersheds, among other applications.The authors present the state-of-the-art in addressing the fundamental scale-bridging problem and provide case studies crossing several levels of scale hierarchy. Scaling Methods in Soil Physics offers novel approaches based on geostatistics, artificial intelligence, wavelet transforms, fractal theory, soil-landscape relationships, computer simulations, and advances in theories of scale developed and tested to facilitate the use of soil physics data in a wide variety of soil/land/earth-related applications.
