Jets and plumes are shear flows produced by momentum and buoyancy forces. Examples include smokestack emissions, fires and volcano eruptions, deep sea vents, thermals, sewage discharges, thermal effluents from power stations, and ocean dumping of sludge. Knowledge of turbulent mixing by jets and plumes is important for environmental control, impact and risk assessment. Turbulent Jets and Plumes introduces the fundamental concepts and develops a Lagrangian approach to model these shear flows. This theme persists throughout the text, starting from simple cases and building towards the practically important case of a turbulent buoyant jet in a density-stratified crossflow. Basic ideas are illustrated by ample use of flow visualization using the laser-induced fluorescence technique. The text includes many illustrative worked examples, comparisons of model predictions with laboratory and field data, and classroom tested problems. An interactive PC-based virtual-reality modelling software (VISJET) is also provided. Engineering and science students, researchers and practitioners may use the book both as an introduction to the subject and as a reference in hydraulics and environmental fluid mechanics.

Challenging problems involvrllg jet and plume phenomena are common to many areas of fundamental and applied scientific research, and an understanding of plume and jet behaviour is essential in many geophysical and industrial contexts. For example, in the field of meteorology, where pollutant dispersal takes place by means of atmospheric jets and plumes formed either naturally under conditions of convectively-driven flow in the atmospheric boundary layer, or anthropogenically by the release of pollutants from tall chimneys. In other fields of geophysics, buoyant plumes and jets are known to play important roles in oceanic mixing processes, both at the relatively large scale (as in deep water formation by convective sinking) and at the relatively small scale (as with plume formation beneath ice leads, for example). In the industrial context, the performances of many engineering systems are determined primarily by the behaviour of buoyant plumes and jets. For example, (i) in sea outfalls, where either sewage or thermal effluents are discharged into marine and/or freshwater environments, (ii) in solar ponds, where buoyant jets are released under density interfaces, (iii) in buildings, where thermally-generated plumes affect the air quality and ventilation properties of architectural environments, (iv) in rotating machinery where fluid jet~ are used for cooling purposes, and (v) in long road and rail tunnels, where safety and ventilation prcedures rely upon an understanding of the behaviour of buoyant jets. In many other engineering and oceanographic contexts, the properties of jets and plumes are of great importance.

Böden sind eine unserer wichtigsten Lebensgrundlagen. Sie liefern Wasser und Nährstoffe an die Pflanzen, die uns ernähren, und halten Schadstoffe vom Grundwasser fern. Aber sie sind auf vielfältige Weise gefährdet. Ihr Schutz ist daher eine der wichtigsten Aufgaben für Wissenschaft, Politik und Gesellschaft. Ein Team anerkannter Autoren beschreibt in der 16. Auflage dieses renommierten und erfolgreichen Lehrbuchs · die Vorgänge der Bodenbildung und -entwicklung, · die physikalischen, biologischen und chemischen Eigenschaften der Böden, · Nähr- und Schadstoffe, · die verschiedenen Bodensystematiken (Deutschland, USA, FAO-UNESCO, WRB), · die wichtigsten Böden und Bodenlandschaften Mitteleuropas und der Welt, · die Nutzungsbewertung der Böden · Grundsätze des Bodenschutzes Die 16. Auflage wurde völlig neu bearbeitet und neu strukturiert. Für das Studium überflüssiges Wissen ist gekürzt. Einige Kapitel wurden aber auch stark erweitert, v.a. die Bodenbiologie. Die Grafiken sind erstmals 2-farbig und es gibt drei Tafel mit Farbfotos von Bodenprofilen. Wer sich mit Böden befasst, braucht dieses Buch.

This book offers a comprehensive study on the subject of ocean disposal of treated and untreated sewage waste. The early chapters cover the philosophy of outfall design, properties of sewage from developed towns and an overview of water quality regulations in New Zealand, Great Britain and the U.S. Alternative ways of satisfying these regulations are discussed. The book also provides information required to design outfall pipelines and diffusers.
