dc.description.abstract PREFACE At the 12th International Congress of Soil Science, held in New Delhi, India in February 1982, a proposal by the Dutch Soil Science Society to host an international symposium on water movement in heavy clay soils was accepted. The symposium was to be sponsored by the International Society of Soil Science (ISSS). To further develop contacts between pedologists and soil physicists, it was decided that the symposium be organized by Commissions I (Soils Physics) and V (Soil Genesis, Classification, and Cartography) of the ISSS. Later, it was also agreed that the symposium be co-sponsored by the European Geophysical Society. In the fall of 1982 an organizing committee was formed consisting of G.B. Bolt (Chairman), J. buma (Secretary), and W.A. Blokhuis, J.W. van Hoorn, P.A.C. Raats, K. Rijniersce, and G.P. Wind (members). The ISSS was represented on an ad hoc basis by its Secretary General W.G. Sombroek. Secretarial assistance was provided by Mrs. M. Rijk of the Netherlands Soil Survey Institute. At its first meeting the organizing committee decided to expand the scope of the symposium to cover not only water but also solute movement in heavy clay soils, thus including aspects of ISSS Commission I1 (Soil Chemistry). The three-day symposium was held from 21 to 29 August 1984, at the International Agricultural Centre, Wageningen, The Netherlands. Organizational aspects were handled by Mrs. L. Hotke and Mrs. E. van de Wetering. The schedule included a reception given by the Dutch Ministry of Agriculture and Fisheries, a visit to the International Soil Reference and Information Centre (ISRIC) in Wageningen and, of course, a symposium dinner. Following the symposium were two day-long excursions. The first, organieed by K. Rijriiersce of thc IJsselmeerpolders Development Authority, was to very young clay soils in a newly-reclaimed polder. The second, to young and old riverine clays near the Rhine, was organized by M. Kooistra, J.H.M. Wtlsten, V L.W. Dekker, and J. Bouma of the Netherlands Soil Survey Institute, and by R. Miedema and J. Versluys of the University of Agriculture, Wageningen. Excursion guides were prepared, but they have not been reproduced in these proceedings - The following themes were covered in the symposium: 1. Development of structural patterns in swelling and shrinking clays; 2. Transport phenomena: water movement; 3. Transport phenomena: solute transport; 4. Measurement and simulation techniques. The sessions in which these themes were covered were chaired by G.H. Bolt, W.A. Blokhuis, J.R. Philip, G.D. Towner, D.H. Yaalon, and L.P. Wilding. Prior to the symposium, ten individuals with particular experience in one of the four themes were asked to submit a keynote paper of a maximum ten pages in length. Each paper was to be presented during a half hour period, at least fifteen minutes of which was to be devoted to discussion. This unusual timing was possible because of the fact that the participants had received the papers well before the symposium took place, and had been asked to submit their comments and questions in writing preferably before, but also during, the symposium. Voluntary papers were also invited, to be submitted in the form of expanded abstracts with a minimum of 2 and a maximum of 4 pages. These were available to all participants during the symposium. To stimulate meaningful discussions, the authors were asked to include specific information, such as tables, graphs, and selected key references. They were encouraged to submit the complete papers elsewhere as well. Each expanded abstract was reviewed by a member of the organizing committee. Preprints of keynote papers and expanded abstracts were prepared by Messrs. T. Beekman and J. van Manen of ILRI. The present book consists of the keynote papers, the expanded abstracts, and the discussions during the symposium, the latter only insofar as questions and answers were submitted in writing, to the VI symposium committee. Thus, not all exchanges are reflected in these Proceedings. All authors were given the opportunity to submit corrected versions of their papers. Heavy clay soils occupy large areas of the world. Their complex and variable structure leads to intricate patterns of water and solute movement. This book shows that the soil surveyors, experimentalists, theorists, and the scientists who are building (computer) models are, individually and jointly, facing up to the challenges that these soils present. We hope that the symposium and these proceedings will prove to be a contribution towards a more mature assessment of the problems and potentials of heavy clay soils. The editors. en_US
