Editorial Reviews Review "The book presents many pedotransfer results that will be useful in helping engineers, soil and environmental scientists, and researchers across a range of soil-related disciplines.

This book will help readers develop a greater understanding of how to parameterize hydrological processes by using the availble information The authors present state-of-the-art in addressing the fundamental issues of simplicity, reliability, accuracy, and utility of pedotransfer functions to predict soil hydrologic properties and processes and related phenomena The book relates pedotransfer functions to water and solute models and gives excellent references to these models Obtaining parameters of hydrological processes 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 estimating soil hydraulic and related parameters from readily available soil data. Pedotransfer functions provide such estimates and translate data we have into data we need.

Development of Pedotransfer Functions in Soil Hydrology covers many pedotransfer results that will be useful in helping scientists and engineers across a range of soil-related disciplines. The first single-source reference in this fast developing field, the book will help readers develop a greater understanding of how to parameterize hydrological processes using information on soil texture, soil structure, organic matter content, chemical, mineralogical, and mechanical properties, topographical information and remote sensing data.

The book contains contributions by acknowledged experts from across the globe and provides case studies for several regions of the World. The authors present the state-of-the-art in addressing the fundamental issues of accuracy, reliability, and utility of pedotransfer functions. Development of Pedotransfer Functions in Soil Hydrology offers novel approaches based on data mining, artificial intelligence, fuzzy logic, and modern statistics to discover pedotransfer relationships to estimate soil water retention, soil hydraulic conductivity, parameters of solute retention and transport, and parameters of soil erosion processes.

Both developers and users of pedotransfer functions will benefit from the comprehensive reviews, specific examples, and user-oriented approaches that the book presents.
