EBOOK - Environmental Fluid Mechanics - Memorial Volume in honour of Prof. Gerhard H. Jirka (IAHR Monographs) (W. Rodi & M. Uhlmann) - Cơ học chất lỏng môi trường (452 Trang).

This book contains written versions of papers presented at the Gerhard H. Jirka Memorial Colloquium on Environmental Fluid Mechanics held June 3–4, 2011, at the Karlsruhe Institute of Technology (KIT) in Karlsruhe, Germany. The colloquium was organized to honour and commemorate Prof. Gerhard H. Jirka who was one of the most outstanding scientists of our days in the area of Environmental Fluid Mechanics.

23 world leading scientists in the field accepted the invitation to present keynote lectures at the colloquium and paid tribute to Prof. Jirka by reporting on their recent work. Environmental Fluid Mechanics represents the scientific and applied study of fluid motion and its implications on the transport and distribution of mass and heat in natural and man-affected systems in the environment. Due to the growing awareness of and concern about the state of our environment and the strong influence of flow processes on this, the discipline is of prime topicality and importance.
The contributions in this book are restricted to the hydrosphere as environment because this was the working area of Prof. Jirka and, naturally, also the colleagues paying tribute to him as authors work in this area. However, even this subarea is very rich in different complex flow-related phenomena, which is reflected by the wide range of contributions to this book.
These provide information on recent developments in the following key areas of Environmental Fluid Mechanics: Shallow Flows (5), Fluvial Hydraulics (5), SmallScale Phenomena (3), Jets and Stratified Flows (3), Gravity Currents (4), and Mass Transfer (3) and include experimental, theoretical and numerical studies. The numbers in parentheses indicate the number of contributions in each area. Heading off the book is a paper by former co-workers of Prof. Jirka, summarizing his scientific work and achievements, and this paper forms an essential element of the memorial volume.
