Book Description
The soil water retention curve, the saturated hydraulic conductivity and the unsaturated hydraulic conductivity function are basic soil hydraulic functions and parameters. Ample apprehension of the soil hydraulic functions and parameters is required for a successful formulation of the principles leading to sustainable soil management, agricultural production and environmental protection. From these, all the other parameters, required in the solution of the practical tasks, are derived. The basic soil hydraulic functions are strongly dependent upon the soil porous system. The development of models is characteristic by the gradual transition from the simplest concepts up to the sophisticated approaches, which should correspond to the visual reality studied by soil micromorphology. 2 Soil Porous System and Soil Micromorphometry 2.1 An Overview on the Quantification of the Soil Porous System Quanti? cation of the soil porous system consists of classi? cation of soil pores, ch- acterization of the soil pores shapes and the estimation of the pore size distribution function. When the hydraulic functions of the soil pores are considered, the following laws of hydrostatics and hydrodynamics are applied as best ? tting to the classi? cation criteria of the size of the pores (Kutilek and Nielsen 1994, p. 20, Kutilek 2004): A. Submicroscopic pores that are so small that they preclude clusters of water molecules from forming ? uid particles or continuous water ? ow paths.

Book Description
The Amazon Basin is arguably both one of the least-known and the most complex linguistic regions in the world. It is the home of some 300 languages belonging to around twenty language families, plus more than a dozen genetic isolates, and many of these languages (often incompletely documented and mostly endangered) show properties that constitute exceptions to received ideas about linguistic universals. This book provides an overview in a single volume of this rich and exciting linguistic area. The editors and contributors have sought to make their descriptions as clear and accessible as possible, in order to provide a basis for further research on the structural characteristics of Amazonian languages and their genetic and areal relationships, as well as a point of entry to important cross-linguistic data for the wider constituency of theoretical linguists.

Book Description
Cryosols – permafrost – occupy a unique part of the earth and have properties greatly different from other soils. They also occur where the greatest impact of global warming is predicted. This is the first book bring together the leading researchers in the area of permafrost soils to produce a review of the geography, cryogenic soil forming processes, ecological processes, classification and use of soils that are affected by permafrost.
