This volume contains most of the scientific contributions to the workshop ``Prediction of Agricultural Nonpoint Source Pollution: Model Selection and Application'' held in Venice, in the historic Ca' Vendramin Calergi, in June, 1984. Other contributions of specialists who were not able to attend the workshop have also been included in an attempt to make the work more complete. It is hoped that this collection will be useful to planners who operate in the field of agricultural diffuse source pollution, since several contributions are state-of-the-art presentations and others are specialized studies by American and European researcher.

The book summarizes actual and/or relative environmental impacts resulting from existing and emerging agricultural production technologies, as practised in the USA. Case studies of environmental impacts of agricultural practices are discussed in one chapter, while separate chapters consider water and soil, air quality, noise and waste impacts. Air pollutants from cultivation operations, burning, agricultural vehicles, harvesting and grain handling, pesticide applications, wind erosion etc. are all considered. Noise produced by agricultural activities and exposure patterns for agricultural workers are examined. An annotated bibliography is included for the environmental impacts discussed in the text. Emerging agricultural production technologies such as nitrogen fixation, genetic engineering, plant growth regulation, erosion control, water management and waste utilization etc. are also compared for efficiency and environmental impacts.

Following years of research, the first bored tunnel in soft soil in the Netherlands, the Tweede Heinenoord tunnel, was completed in 1998. Since then, Dutch engineers have increased their knowledge of soft soil tunnelling, with a significant and important part of this research being carried out by GeoDelft, the Dutch National Institute of Geo-Engineering. This book contains the most important publications by GeoDelft on the subject of soft soil tunnelling, focusing on the period from 1992 to the present, it is divided into four main headings: field measurements; grout behaviour; model testing; and numerical analysis. This impressive overview of the progress made in the Netherlands in soft soil tunnelling research over more than a decade is a valuable resource to those working in soft soil tunnelling worldwide.

With descriptions of hundreds of the most important environmental and ecological models, this handbook is a unique and practical reference source. The Handbook of Environmental and Ecological Modeling is ideal for those working in environmental modeling, including regulators and managers who wish to understand the models used to make assessments. Overviews of more than 360 models are easily accessed in this handbook, allowing readers to quickly locate information they need about models available in a given ecosystem. The material in the Handbook of Environmental and Ecological Modeling is logically arranged according to ecosystem. Each of the sixteen chapters of the handbook covers a particular ecosystem, and includes not only the descriptions of the models, but also an overview of the state-of-the-art in modeling for that particular ecosystem. A summary of the spectrum of available models is also provided in each chapter. The extensive table of contents and the easy-to-use index put materials immediately at your fingertips.
