Opis

The GAMM Committee for Scientific Computing organizes workshops on subjects in Scientific Computing. These workshops are intended to bring researchers from engineering application and mathematical theory together, to provide a platform for discussion and scientific exchange and to further new research fields. st The series of such workshops was continued in 1995, October 12-13, with the 1 GAMM-Seminar at ICA Stuttgart on the special topic "Modelling and Computation in Environmental Sciences" at the Institute for Computer Applications, Universitiy of Stuttgart. The seminar was attended by 75 scientists from 5 countries and 26 lectures were given. The list of topics contained lectures on ground water and soil water flow and transport, heterogeneity, density driven ground water flow, homogenization and multi-scale modelling, special discretization schemes, adaptivity, multi-grid me thods, and parameter identification. Special thanks are due to Prudence Lawday, Oktavia Klassen and Gerd Grieshei mer, who carefully compiled the contributions to this volume."
