Anniversary Issue

This section of the issue of Geophysics is draw from a collection of papers originally submitted for a monograph on engineering and groundwater geophysics. It is a mixture of tutorial, new developments, and case histories focused on seismic methods. This introduction will review the evolution of this section and introduce each of the papers. These papers complement the overview presented by Dobecki and Romig (1985) in the Golden Anniversary Issue of Geophysics. That paper reviews the history, summarizes the state of the art, and attempts to predict possible future developments.

Qualitative Data Analysis Software

Summary The aim of this paper is to provide an overview of the ‘state of the art of QDA or CAQDAS software. The author uses Kahneman’s ideas about slow and fast thinking as a framework. Slow thinking in the context of CAQDAS is related to researcher driven analysis and fast thinking to tool- and data driven analysis. The paper is divided into two parts. In the first part, the author describes trends and new developments and in the second part, she offers a critical appraisal.

Agricultural Meteorology

The papers presented at this meeting have given us a comprehensive account of the state of the art in what one is tempted to call ‘forest meteorology’ though ‘meteorological forestry’ is probably nearer the mark. Older members of the audience like myself who can recall the descriptive and anecdotal nature of the subject in the early 1950s have enjoyed hearing how it has come of age through the painstaking collection of measurements in the field and through the emergence of principles that have guided the development of mathematical models. Forest meteorologists have been fortunate that much of the foundation of their subject has been laid by the pioneers of agricultural meteorology who have had an easier task experimentally and are therefore a little ahead, but not much! A psychologist might have felt quite at home at this meeting because there have been so many references to the way systems ‘behave’. It seemed that systems were ‘well behaved’ when processes being observed were consistent with theoretical predictions where they existed, or with intuition where they did not. Bad behaviour (by a forested catchment in Rob Roy’s territory for example) meant a discrepancy between performance and expectation. We should remember, however, that the recognition of so-called bad behaviour is the first step towards new developments in most branches of science; and that progress in forest meteorology will depend on the skill and patience of people who feel challenged to tackle the anomalies, the uncertainties and the loose ends that we have heard about yesterday and today.

Urban Wastewater Treatment

Nitrogen removal is the most complicating factor in urban wastewater treatment. Nitrification accounts for more than 50% of the oxygen need and requires long sludge ages. Denitrification is often hampered by a lack of COD. In fact it would be better to use this COD to generate methane. Recent research has shown that it is possible to remove ammonium by anaerobic ammonium oxidation leading to a much reduced need for aeration energy, no need for COD in the N-removal, and a considerable lower sludge production. The state of the art and the potential role in urban wastewater treatment are discussed.

The main aim of this paper is to give a review on the state of the art of available processes for the advanced treatment of wastewater from a Textile Processing Industry (TPI). After an introduction to the specific wastewater situation of the TPI the paper reviews the options of process and production integrated measures. The available unit processes and examples of applied combinations of unit processes are described. A special place is given to the in-plant treatment, the reuse of the treated split flow or mixed wastewater and the recovery of textile auxiliaries and dyes. As a conclusion the paper gives some examples of applied and effective end-of-pipe-steps.

The Times

In accepting an invitation to speak in this symposium all the speakers today are exposing themselves to great hazards, and none more so than me. The capabilities of computers, their variety, the associated instrumentation, are all expanding so rapidly and changes are taking place with such a frequency that we are all inevitably out of date. The mere fact of having to prepare an abstract in March for a meeting in August presents hazards. Who knows what revolution in the state of the art will be announced in the meantime?My own project was started four or five years ago so that we may be considerably behind the times. As time went along we were able to take advantage of some of the new developments in technology but in many cases we were simply too far along to make adjustments. As a result, if one were to ask whether our project should serve as a model or whether we would do it the same way again, the answer would have to be “no.” On the other hand, some of the features are good and may serve as examples for future projects. The reader will have to decide.
