The purpose of this book is to analyse and discuss a series of topics related with environmental conservation, land-use planning and management and impact prevention as seen from the perspective of the Earth Sciences, but with an inte- grated, interdisciplinary approach. The contributions included in the book intend to give an overview of existing problems and trends and to point out certain lines along which work and/or actions will be par- ticularly needed in the near future. In short, they intend to show where we stand now with regard to those problems and in what direction we should move....

This volume consists of papers presented at the Fifth International Workshop on Computer Aided Scheduling of Public Transport, which was held in Montreal from August 19th to the 23rd, 1990. Since the first Workshop in Chicago in 1975 the field had matured considerably. In 1975, there were no presentations that described systems which had been implemented and used on a regular basis. By 1980, in Leeds, and certainly by 1983, in Montreal, several systems were in regular use. They were based on both heuristics and mathematical programming techniques. In 1990, there were more than one hundred...

Chemical modifications of supracrustal materials have occurred at various times in the Earth's history. This reference book gives an overlook over themost recent findings of isotope research in the sedimentary environment. The reader, interested in the diagnetic evolution of sediments, can use the book as a tool for the understanding of mineral-water interactions in the supracrustal level.

This volume outlines an experimental investigation of the nature of submarine gravity-driven currents of suspended sediments which are reflected or deflected against obstacles such as a seamount or barrier.

Combining field research of outcrop geology with investigations of the recent formation of carbonate rocks in coastal environments, the author presents an introduction to sequence stratigraphy. Using computer simulations, the book focuses on four areas: the geometry of carbonate wedges; sequences comparable with geotectonic cycles; their influence by geoidal pulses; and the determination of these geoidal pulse distributions in geologic time.

This volume addresses the problems involved in the disposal of toxic wastes. It focuses specifically on the underground deposition of hazardous substances and the long-term safety of underground repositories in salt rocks.

Based on a comparative analysis of two case studies, this book presents a comprehensive and systematic examination of urban water management in the light of environmental theory. A complex model structure of the subject matter portrays it as a system of interlocking subsystems covering the management structure, the inventory and the urban hydrological conditions. The system itself is also viewed within its wider urban ecological context of interaction between urban and industrial development, land use and the physical environment. This analytical grid also provides the framework for the...

The book on deposition, diagenesis, and weathering of organic matter-rich sediments is a summary of seven years of research work of the author at the Institute of Petroleum and Organic Geochemistry in J}lich. It contains a comparision of various depositional environments (lakes, deltas, seas)with respect to organic matter characteristics, a special chapter on the deposition of the Posidonia shale, a summary of organic matter maturation and related petroleum generation, and a chapter on the use of maturationparameters as calibration tools for numerical modelling of temperature histories of...

This volume corresponds to a course of the International Summer School of Theoretical Geodesy, held every 4 years under the sponsorship of the International Association of Geodesy. This particular course, given at the International Centre for Theoretical Physics in Trieste, has been dedicated to the theory of satellite altimetry as a response to the increasing need of scientific work in this field due to important recent and forthcoming space missions. The course was conceived to supply a good theoretical basis in both disciplines, which are deeply involved in the analysis and use of the...

In July 1995 the XXI General Assembly of the International Union of Geodesy and Geophysics was held in Boulder, Colorado. At this meeting the International Association of Geodesy (lAG) organized a number of symposia to discuss scientific developments and future directions in a number of areas. One of these symposia was G3, Global Gravity Field and Its Temporal Variations. This symposium consisted of four invited and 36 contributed papers. The contributed papers were given as oral or poster presentations. This proceedings volume represents the written contributions of the four invited papers...
