High Resolution Flow Modelling in Hydrology and Geomorphology

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.
