Opis

The book concentrates on hydrological and geomorphological processes in mountain rivers with the majority of the contributions focusing on the Alps.
Methods and results of research in solid load transport and river bed dynamics are presented by international authors. The authors come from earth science and engineering institutions and both practical and theoretical aspects of mountain river research are addressed.
The book is a valuable guide and source of information on problems of environmental planning and protection, river management and hazard assessment.
