Nel Belgio, per citarne alcuni, col decreto 10 aprileil Ministro dell'Interno Eolin-Jaequemyns, in esecuzione del de- creto Eeale 7 agosto col quale fondavasi F Ufficio di tra- duzione, disponeva da quell' Ufficio si pubblicasse nu Bollettino Bibliografico delle opere Periodiclie, che un anno appresso nel vedeva la luce 1.

Napoli Series on Physics and Astrophysics ; 8.Layered soils exhibit vertical textural or structural contrast and are ubiquitous. Textural contrast is a result of translocation via eluviation—illuviation, bioturbation, erosion, deposition or inheritance of textural stratification Phillips Surface soils are usually rich in organic matter and have more frequent wetting and drying, and freezing and thawing, creating different soil structure from the subsoil.

One typical measure of the pedogenic structure difference is the bulk density. Structural and textural contrasts can also result from anthropogenic effects, such as tillage operations and other soil management practices.

Reclamation using soil covers creates distinct layers in soil purposely or unintentionally, because the soil cover materials may come from a different location than the local soil. The formation of natural soil layers can be a long-term process, which is an integrated result of a complex suite of physical, chemical and biological processes.

However, in some cases, such as the artificial layers in reclamation soils and compacted layers in disturbed soils, layers can form in soils in a short time. Layers, such as hard pan, may restrict growth of vegetation, while, in some cases, layers are beneficial for preventing salinity or improving soil water storage in semi-arid regions. This could lead to less nutrient loss and minimizes potential pollution of groundwater beneath such fields. Further, soil layering also leads to increased soil water storage capacity and improved ecosystem productivity in semi-arid zones.

The reduced water flow and increased soil water storage through layering has been investigated mainly in soils with strong textural contrast. The phenomenon is explained by two mechanisms Alfnes et al. A capillary barrier develops when an unsaturated fine-textured soil layer is underlain by another unsaturated coarser porous material Stormont et al. Due to the capillary break, a substantial amount of water remains in the fine-textured soil layer and will only flow into the underlying layer until a critical soil water potential is reached.

Water storage capacity of the finer layer is controlled by unsaturated hydraulic properties of coarser layers. Therefore, there is increased water storage capacity of soils beyond the level that would normally drain under gravity. Capillary barriers work better in unsaturated conditions, because in this case, capillary forces and, thereby, water retention in finer layers is higher and the unsaturated hydraulic conductivity of the finer layer can be larger than that of the underlying coarse layer.

With wetting, the difference between the unsaturated hydraulic conductivities of finer and coarser layer decrease and capillary barrier effect vanishes Aubertin et al. When the hydraulic conductivity flow rate of a fine-textured layer is less than that of an overlying coarser layer, water will accumulate in the upper layer, due to a hydraulic barrier effect Scott Soils often exhibit a variety of small-scale heterogeneities such as cracks, inter-aggregate or structural pores, decayed root channels and other types of macro- and coarse micropores.

The reason is that the buffer capacity, as well as biological activity, that are found in the organic-rich upper soil horizons and that are vital to the degradation of pollutants, are generally weaker or absent altogether in the deeper layers. Thus the danger of groundwater contamination is increased due to preferential flow.

The theoretical foundation for the phenomenon of preferential flow was laid half a century ago by Barenblatt et al. The theory was initially formulated in terms of the seepage of liquids in fissured rocks.

The first step was the introduction of the concept of mobile and immobile water in a porous medium by Gaudet et al. This was followed by Beven and Germann, who formulated the theory of flow in soils containing macropores. The fundamental problem of disequilibrium due to macroporosity was discussed by Baveye and Sposito The theorywas later extended, using numerical approaches, to the concept of dual porosity Moench, ; Arbogast,and specialized for soils by Gerke and van Genuchten Nkedi-Kizza et al.

Othmer et al. Recent advances in preferential flow research were reviewed by Jarvis and Gerke Preferential flowin realmacropores or non-capillary pores. At least in principle, Richards' equation is not applicable.

Instead, the kinematic wave equation or the simple Hagen— Poiseuille equation can be applied. Fluxes are significantly accelerated compared to those in the pores. Preferential flow in inter-aggregate pores, denoted also as interpedal or structural pores. Sometimes inter-aggregate pores are described as macropores, but this terminology neglects the principal difference between non-capillary and capillary pores. Richards' equation is applicable since the pores are in the category of capillary pores.

The fluxes are accelerated compared to those in the intrapedal pores of the matrix when infiltration and redistribution are considered, but less accelerated compared to the fluxes in Type 1. Some authors question the applicability of Richards' equation in those coarser micropores. Fingering due to the instability on the wetting front.

This occurs most frequently at the interface of a less permeable layer above a more permeable one. In numerical models, apparent fingering can be induced by numerical instabilities. Fluxes are comparable to those of Type 2. Preferential flow due to spatial irregularities or temporal dynamics in soil wettability or water repellency.

This type of preferential flow is often assumed to occur when the initial soilwater content is belowa critical value. Local-scale heterogeneities and non-equilibrium preferential flow are obviously expected to be strongly related, but the quantification of this relationship remains a challenge. Given the important effects of preferential flow on water and solute transport, a large body of literature can be found dealing with the description of preferential-flow pore networks and the mechanisms of macropore flow, especially at the pedon scale.

The use of morphometric data in combination with soil physical characteristics is recognized as particularly relevant. Recent advances allow the complex geometry of the pore space to be quantified by means of tomography, magnetic resonance and image analysis. New devices and measurement techniques are now available, such as time domain reflectometry and disc permeametry, allowing better observations of preferential flow at the pedon scale.

Additionally, insight into the physical influence of local-scale heterogeneities on soil processes can now be gained by appropriately modelling water and solute transport behavior in natural soils with different structures.

Accordingly, the body of knowledge on preferential flow available at present, both theoretical and experimental, is extensive. Nevertheless, knowledge gaps still exist. The purpose of this Special Issue is to fill some of these gaps. The papers selected for the Special Issue address a range of issues, from the basic principles governing the generation of preferential flow at the pore scale, to the flow mechanisms and the microscale properties of the porous soil system, and to the problem of upscaling.

The papers show that better observations using new devices, and analyzed using innovative analytical and predictive approaches, may bring us toward a better understanding and prediction of preferential flow in structured soils. These papers describe the present state of the art.

The limits of applicability of Richards' equation as a function of pore size, and the fluxes involved, are investigated in these papers.Autori: in maiuscolo, curatori: normale.
