Poor soil and water management are often related to insufficient or poor rainfall distribution around the world. In modern agriculture, over-cultivation, deforestation, overgrazing, and high dependence on an irrigated cropping system with water-intensive crops increase soil and water erosion. This book examines ways of improving soil moisture management to support environmental, food, social, and economic security under a sustainable ecosystem.

This book covers all aspects of Electromagnetic Aquametry. It summarizes the wide area of metrology and its applications in electromagnetic sensing of moist materials. The physical properties of water in various degrees of binding interacting with electromagnetic fields is presented by model systems. The book describes measurement methods and sensors in the frequency domain, TDR-techniques for environmental problems, methods and sensors for quality assessment of biological substances, and nuclear magnetic resonance techniques. Environmental sciences, as well as civil and geoengineering, fossil fuels, food and pharmaceutical science are the main fields of application. A very wide frequency sprectrum is used for dielectric measurement methods, but the microwave range is clearly dominant. Multiparameter methods as well as methods of principal components and artificial neural networks for density independent measurements are described.

The transfer of heat and moisture through textiles is vital to the manufacture and design of clothing, technical and protective textiles. Continued advances in textile processing technology, the growth of manufactured nonwovens and the application of nanotechnology have resulted in a wealth of research in order to characterise the behaviour of these materials. Thermal and moisture transport in fibrous materials provides a comprehensive guide of the technological developments and scientific understanding in this area.The first section summarises the structure, geometry and stereology of

Mechanics of Fluid Saturated Rocks presents a current and comprehensive report on this emerging field that bridges the areas of geology and mechanics. It is of direct interest to a wide spectrum of earth scientists and engineers who are concerned with upper-crust mechanics and fluid movements, the most important fluids being oil and water. This authoritative book is the result of a collaborative effort between scientists in academic institutions and industry. It examines important issues such as subsidence, geological fault formation, earthquake faulting, hydraulic fracturing,

During the West African Monsoon, convective systems generate the largest part of annual precipitation. We investigate their predictability by conducting high-resolution ensemble simulations with the COSMO model, focusing on the impact of the land surface. Are land-surface – atmosphere interactions in West Africa as important for precipitation forecasts as larger-scale conditions? What are the main physical processes?
