135,18€ + 10% EM CARTÃO

portes grátis

 This work on the dynamics of glaciers, ice sheets and ice shelves relates the distribution of isotopes and impurities in ice masses to ice flow, to the key zone close to the ice-substratum interface and to the mechanisms effective in the contact zone between glacier and ocean.

Ice Composition And Glacier Dynamics

de Reginald D. Lorrain e Roland A. Souchez

118,59€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 The idea behind the title of this book is that the study of ice composition can shed some light on the various processes operating at the ice- bedrock and ice-ocean interfaces and more generally on glacier dy- namics.

Numerical Simulation Of Canopy Flows

de Gunter Gro

59,61€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Starting with the description of meteorological variables in forest canopies and its parameter variations, a numerical three-dimentional model is developed. Its applicability is demonstrated, first, by wind sheltering effects of hedges and, second, by the effects of deforestation on local climate in complex terrain. Scientists in ecology, agricultural botany and meteorology, but also urban and regional lanners will profit from this study finding the most effective solution for their specific problems.

Karst In China - Its Geomorphology And Environment

de Marjorie M. Sweeting

118,59€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 The writer has been occupied with karst problems for 50 years and first visited China in 1977 as leader of a Royal Society delegation of British geomorphologists - the first delegation from the UK to visit China since the inauguration of the new China and at the end of the Cultural Revolution (Sweeting 1978). It was clear from that visit that a study of the Chinese karst would help our understanding of the problems of karst development and that many of the geomorphological difficulties which at times had stultified karst thinking in Europe, might gain from the Chinese approach and ideas. First, for example, the Chinese karst is in its initial stages much more fluvial in origin than that of the Dinaric karst. Problems which worried European karst geomorphologists, such as dry val leys and the debates about karst base levels and the water table have not worried the Chinese so much. The development of the S Chinese karst has proceeded from an original fluvially eroded land scape which was later karstified. Secondly, the large area distri bution of limestones in China, and the spectacular areas of karst, compared with the often relatively small areas of karst in Europe, have focussed our attention upon the fundamental issues of karstification, rather than upon the endless discussions on the ori gin of the small and less significant landforms in the karst.

Earth Surface Systems

de Richard J. Huggett

118,59€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Discussions of "systems" and the "systems approach" tend to fall into one of two categories: the panegyrical and the disparaging. This tilt at the systems approach is mild indeed compared with the com- ments of an anonymous reviewer of a paper by myself concerned with the systems approach as applied to the soil.

Karst Hydrology - With Special Reference To The Dinaric Karst

de Ognjen Bonacci

118,59€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Karst is characterized particularly by special landforms and sub- surface drainage. It is equally true that the first theories on water circulation in karst were developed according to ex- periences in the Dinaric karst.

Processes In Karst Systems - Physics, Chemistry, And Geology

de Wolfgang Dreybrodt

158,34€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 <B>Karst Systems </B>deal with the question of how the subsurface drainage system, typical of Karst areas develops from its initial state to maturity. Equal attention is given to physical, chemical and geological conditions which determine karstification. The reader will find discussions of mass transport, chemical kinetics, hydrodynamics of fluxes, and the role of dissolution and precipitation of Calcite as they occur in experiments and natural environments. It offers a wealth of information on a complex natural system to hydrologists, hydrochemists, geologists and geographers.

Desertification - Natural Background And Human Mismanagement

de Monique Mainguet

95,40€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Controversial, and often discussed with passion and vehemence, desertification is a problem on whose solution the survival of millions of humans is dependent. This book aims at an understanding of what is commonly called "desertification" - a term which has a connotation of irreversibility, spreading and emergence of desert-like landscapes: "land degradation" is proposed to replace it. The purpose is to present what has happened in reality, and what might be done. Illustrative worldwide analyses allow a more realistic evaluation of global land degradation. Each level of technology, excessive or insufficient, creates its own mismanagement. This is reflected in a decrease in soil productivity and eventually land degradation. The benefit to the reader is an awareness of the ecozones which have undergone the most severe land degradation, and a global overview of the phenomena, mechanisms and existing solutions.
