This special CATENA volume is an outcome of the Workshop on Erosion,
Transport and Deposition Processes in Semi-Arid and Arid Areas. The
Workshop, held in Israel in the Spring of 1987 was organized as a
joint venture between the International Commission on Continental
Erosion (IRHS) and the Commission on Measurement, Theory and
Application in Geomorphology (IGU). This cooperation reflected the
need for scientific interchange between hydrologists and
geomorphologists, both groups having a common interest in the study of
runoff and erosion processes. The meeting improved avenues of
communication and enhanced cooperation in the boundary area shared by
hydrology and geomorphology.
The present volume contains selected papers dealing with geomorphic
and pedo-logic aspects of semi-arid and arid zones. They cover a wide
range of physiographic conditions, extending over four continents
(North America, Europe, Asia and Africa). As might be expected, the
topics covered are highly diversified. Some are theoretical or are of
an applied nature while other papers deal with hillslopes or
channels. Although the temporal and spatial scales differ from one
paper to another, all exhibit a strong interest towards the
understanding of processes shaping the land.
