Practical experience has demonstrated the validity of the formulation of these relationships. Geomorphological systems in such environ- ments are highly complex and difficult to study due to seasonally extreme conditions. This volume contains papers dealing with sediment transport through fluvial systems and relationships between processes and morphological development in fluvial systems. The volume contains selected papers dealing with geomorphic and pedologic aspects of semi-arid and arid zones. They cover a wide range of physiographic conditions, extending over four continents.
Few publications exist in English on the land- forms in the Federal Republic of Germany.
This volume contains a selection of invited papers dealing with the recognition, interpretation and various applications of paleo- sols. Identification of relict features is of special significance for geomorphological inter- pretations and for examinating the influence of climate on geomorphological and pedological processes. It will be important to link the improved data available to much more detailed studies of short-term temporal and spatial changes in surface soil conditions, and of selective transport and depositional processes. The diversity of dune landscapes is astonish- ing. There is probably no other type of land- scape in the world which in its two main elements, land form and land cover, shows so much variation over such short distances.
