High Resolution Flow Modelling in Hydrology and Geomorphology

Looks at exciting developments in sophisticated numerical analysis techniques in the environmental sciences illustrating the application scope for such techniques.
High resolution hydraulic modelling is becoming accepted as a standard research methodology by hydrologists, geomorphologists and engineers. As a consequence of the development of process understanding, numerical analysis techniques and computer power, there is now enormous potential to connect complex flow processes to the landforms they create in a rigorous, quantitative manner that has not hitherto, been possible.
This volume provides an integrated coverage of this topic, outlining major research developments that have taken place. It begins with an introductory chapter on hydraulic theory, and then concentrates on high dimensional and high resolution approaches, detailing current research debates in hydraulic modelling. There is comprehensive coverage of application scope for such techniques including flow development, sediment transport, pollutant transport, catchment hydrology and landform development.
This readable and accessible book provides an introduction to geomorphology students attempting to familiarise themselves with these exciting developments and also gives researchers invaluable articles illustrating the scope for high resolution hydraulic modelling and the fundamental scientific and philosophical problems raised.Eine ausführliche, modern gehaltene Diskussion der Vorteile und neuen Herausforderungen, die sich durch die Einführung komplizierter numerischer Analysen in die Umweltwissenschaften ergeben haben. Sie richtet sich vor allem an Geomorphologen, denen der Zugang zur mathematisch-technisch orientierten Fachliteratur bisher schwerfiel und die sich für neue Entwicklungen auf dem Gebiet der hochauflösenden hydraulischen Modellierung interessieren.

Paul D. Bates is a Professor of Hydrology at the University of Bristol, UK. He is a Fellow of the American Geophysical Union and a Royal Society Wolfson Research Merit Award holder. High resolution hydraulic modelling is becoming accepted as a standard research methodology by hydrologists, geomorphologists and engineers. Recent advances in process understanding, numerical analysis techniques and improvements in available computer power have led to increases in both the space/time resolution and the dimensionality at which fluvial flow problems can be simulated. As a consequence of these developments there is now enormous potential to connect complex flow processes to the landforms they create in a rigorous, quantitative manner that has not, hitherto, been possible. This volume provides an integrated coverage of this topic, which has not previously been available either in the mathematical/engineering or environmental literature, and outlines recent major research developments that have taken place in this field. The book begins with an accessible introductory chapter on hydraulic theory. It then concentrates on high dimensional and high resolution approaches, detailing current research debates in hydraulic modelling. There is comprehensive coverage of an application scope for such techniques, including flow development, sediment transport, pollutant transport, catchment hydrology and landform development. This volume is of particular interest to lecturers and postgraduates in Geography, Engineering, Civil Engineering, Mathematics, Earth and Environmental Sciences, as well as to scientists in the public sector and commerce.
