Abstract
A first outline of the Quaternary landscape evolution of the Kashaf Rud River basin in the drylands of northeastern Iran
Highlights
To obtain robust geomorphic and paleoenvironmental information for the larger region, studies of river systems with catchments of several hundreds to thousands of square kilometers are necessary (Faust and Wolf, 2017) but are still lacking for this region. To fill this gap and to offer future research perspectives for this region, we studied the Kashaf Rud River basin in northeastern Iran with a catchment of several thousand square kilometers during a field expedition in 2019 (Fig. 1)
By combining our field observations with former findings of Ariai and Thibault (1975), we reconstructed the main steps of the Quaternary landscape evolution of the Kashaf Rud River basin as follows: i
The sediments of terrace level T-3 must have been aggraded during the Early Quaternary
Summary
Fragile drylands are among the most sensitive regions to climate change and human activities. To obtain robust geomorphic and paleoenvironmental information for the larger region, studies of river systems with catchments of several hundreds to thousands of square kilometers are necessary (Faust and Wolf, 2017) but are still lacking for this region To fill this gap and to offer future research perspectives for this region, we studied the Kashaf Rud River basin in northeastern Iran with a catchment of several thousand square kilometers during a field expedition in 2019 (Fig. 1). This drylands river basin formed part of a Pleistocene to Holocene human migration corridor, linking western and central Asia (Vahdati Nasab et al, 2013; Fig. 1).
