Beschreibung

This book offers a comprehensive overview of the alluvial fan phenomena, including all terminology, morphology, sedimentology, controlling factors, processes and the human impact.

It combines the knowledge dispersed widely in existing literature with regional case studies, color figures and photographs. The chapters provide a useful basis to understand alluvial fans and a selection of papers attached to each chapter offers additional, more focused reading.
This volume is aimed at engineers, planners and especially students in earth sciences.



Autorentext

Prof. Dan Bowman is Professor Emeritus at the Ben-Gurion University of the Negev, in Beer-Sheva, Israel and at the nearby Achva Academic College. Prior to his retirement in 2007, he worked as an active Lecturer and Professor at the Department of Geography and Environmental Development of the Ben-Gurion University of the Negev for over 25 years. His courses included nearshore circulation, coastal morphology, alluvial fans, tectonic morphology and system approach.

Prof. Dan Bowman has a B.A. and a M.A. in Geography as well as a Ph.D. in Geomorphology.
He has co-authored over 65 scientific publications including peer-reviewed articles in international journals such as Environmental Monitoring and Assessment and Instructional Sciences, scientific reports, technical papers and chapters in collective volumes, conference proceedings a chapter (i.e. in the book Geomorphological Landscapes of the World).
