Download or read book Modelling Soil biosphere Interactions written by Christoph Müller and published by Cabi. This book was released on 2000 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils interact with the biological environment in a number of ways. Our understanding of these interactions can often be enhanced by computer modelling. The primary function of this book is to introduce basic modelling skills and to show how even complex problems in the relationship between soil and the biosphere can be solved using modelling packages. The author presents numerous examples using ModelMaker, an easily learnt software package. Only basic mathematical skills are expected of the reader. A demo of ModelMaker is available on CD from Cherwell Scientific.

This book was released on 2012-12-06 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well known that the interactions between land surfaces and the atmosphere, and the resulting exchanges in water and energy have a tremendous affect on climate. The inadequate representation of land-atmosphere interactions is a major weakness in current climate models, and is providing the motivation for the HAPEX and ISLSCP experiments as well as the proposed Global Energy and Water Experiment (GEWEX) and the Earth Observing System (EOS) mission. The inadequate representation reflects the recognition that the well-known phys ical relationships, which are well described at small scales, result in different relationships when represented at the scales used in climate models. Understanding this transition in the mathematical relationships with increased space-time scales appears to be very difficult, and has led to different approaches; at one extreme, the famous "bucket" model where the land-surface is a simple one layer storage without vegetation; the other extreme may be Seller's Simple Biosphere Model (Sib) where one big leaf covers the climate model grid. Given the heterogeneous nature of landforms, soils and vegetation within a climate model grid, the development of new land surface parameterizations, and their verification through large scale experiments is perceived to be a challenging area of research for the hydrology and meteorology communities. This book evolved from a workshop held at Princeton University to explore the status of land surface parameterizations within climate models, and how observa tional data can be used to assess these parameterizations and improve models.

Download or read book Handbook of Processes and Modeling in the Soil Plant System written by Rolf Nieder and published by CRC Press. This book was released on 2003-09-15 with total page 800 pages. Available in PDF, EPUB and Kindle. Book excerpt: Learn to create and use simulation models—the most reliable and cost-effective tools for predicting real-world results! The Handbook of Processes and Modeling in the Soil-Plant System is the first book to present a holistic view of the processes within the soil-plant-atmosphere continuum. Unlike other publications, which tend to be more specialized, this book covers nearly all of the processes in the soil-plant system, including the fundamental processes of soil formation, degradation, and the dynamics of water and matter. It also illustrates how simulation modeling can be used to understand and forecast multiple interactions among various processes and predict their environmental impact. This unique volume assembles information that until now was scattered among journals, bulletins, reports, and symposia proceedings to present models that simulate almost all of the processes occurring in the soil-plant system and explores the results that these models are capable of producing. With chapters authored by experts with years of research and teaching experience, the Handbook of Processes and Modeling in the Soil-Plant System examines: physical, chemical, and biological soil processes the soil formation and weathering process and its modeling the impact of radioactive fallout on the soil-plant system soil degradation processes and ways to control them water and matter dynamics in the soil-plant system growth and development of crops at various levels of production the potentials and limitations of using simulation models Students, educators, and professionals alike will find the Handbook of Processes and Modeling in the Soil-Plant System an invaluable reference on the soil-plant-atmosphere system and an ideal tool to help develop an effective decision support system.
Download or read book Review and Integration of Biosphere Atmosphere Modelling of Reactive Trace Gases and Volatile Aerosols written by Raia Silvia Massad and published by Springer. This book was released on 2015-07-16 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: When considering biosphere–atmosphere exchange of trace gases and volatile aerosols, significant advances have been made both from an experimental and modelling point of view and on several scales. This was particularly stimulated by the availability of new datasets generated from improvements in analytical methods and flux measurement techniques. Recent research advances allow us, not only to identify major mechanisms and factors affecting the exchanges between the biosphere and the atmosphere, but also to recognize several gaps in the methodologies used in accounting for emissions and deposition in landscape and global scale models. This work aims at (i) reviewing exchange processes and modelling schemes, parameterisations and datasets, (ii) presenting a common conceptual framework to model soil-vegetation-atmosphere exchange of reactive trace gases and aerosols accounting for in-canopy transfer chemical interactions and (iii) discussing the key elements of the agreed framework.

Available in PDF, EPUB and Kindle. Book excerpt: Distributed in the East European countries, China, Northern Korea, Cuba, Vietnam and Mongolia by Academia, Prague, CzechoslovakiaThis book is based on the efficient subsoil model introduced by the authors in 1977 and applied in the last ten years in the design of foundations. From the designer's point of view, the model considerably reduces the extent of the calculations connected with the numerical analysis of soil-structure interaction. The algorithms presented are geared for use on mini- and personal computers and can be used in any numerical method. A special chapter is devoted to the implementation of the model in the NE-XX finite element program package, illustrated with diagrams, tables and practical examples.Besides presenting the energy definition and general theory of both 2D and 3D model forms, the book also deals with practical problems such as Kirchhoff's and Mindlin's foundation plates, interaction between neighbouring structures, actual values of physical constants of subsoils and natural frequencies and shapes of foundation plates.Today, researchers and engineers can choose from a wide range of soil models, some fairly simple and others very elaborate. However, the gap which has long existed between geomechanical theory and everyday design practice still persists. The present book is intended to suit the practical needs of the designer by introducing an efficient subsoil model in which the surrounding soil is substituted by certain properties of the structure-soil interface. When a more precise solution is required, a more sophisticated model form can be used. Its additional degrees of deformation freedom can better express the behaviour of layered or generally unhomogeneous subsoil. As a result, designers will find that this book goes some way towards bridging the above-mentioned gap between structural design theory and day-to-day practice.

Download or read book Terrestrial Biosphere Atmosphere Fluxes written by Russell Monson and published by Cambridge University Press. This book was released on 2014-03-06 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluxes of trace gases, water and energy - the 'breathing of the biosphere' - are controlled by a large number of interacting physical, chemical, biological and ecological processes. In this interdisciplinary book, the authors provide the tools to understand and quantitatively analyse fluxes of energy, organic compounds such as terpenes, and trace gases including carbon dioxide, water vapour and methane. It first introduces the fundamental principles affecting the supply and demand for trace gas exchange at the leaf and soil scales: thermodynamics, diffusion, turbulence and physiology. It then builds on these principles to model the exchange of water, carbon dioxide, terpenes and stable isotopes at the ecosystem scale. Detailed mathematical derivations of commonly used relations in biosphere-atmosphere interactions are provided for reference in appendices. An accessible introduction for graduate students and a key resource for researchers in related fields, such as atmospheric science, hydrology, meteorology, climate science, biogeochemistry and ecosystem ecology.

Available in PDF, EPUB and Kindle. Book excerpt: The land (or 'terrestrial') biosphere strongly influences the exchange of carbon, energy and water between the land surface and the atmosphere. The size of theland carbon store and the magnitude of the interannual variability of the carbonexchange make models of the land surface a vital component in climate models. This thesis addresses two aspects of land surface modelling: soil respiration andphenology modelling, using different techniques with the goal of improving modelrepresentation of land-atmosphere interaction. The release of heat associated with soil respiration is neglected in the vast majorityof large-scale models but may be critically important under certain circumstances. In this thesis, the effect of this heat release is considered in two ways. Firstly, adeliberately simple model for soil temperature and soil carbon, including biologicalheating, is constructed to investigate the effect of thermal energy generated bymicrobial respiration on soil temperature and soil carbon stocks, specifically inorganic soils. Secondly, the mechanism for biological self-heating is implementedin the Joint UK Land Environment Simulator (JULES), in order to investigate theimpacts of the extra feedback in a complex model. With the intention of improving estimates of the parameters governing modelledland surface processes, a data assimilation system based on the JULES land surfacemodel is presented. The ADJULES data assimilation system uses information from the derivative of JULES (or adjoint) to search for a locally optimum parameter setby calibrating against observations. In this thesis, ADJULES is used with satellite-derivedvegetation indices to improve the modelling of phenology in JULES.
