In their Comment, Zeitler et al. do not challenge our results or interpretation. Our study does not disprove coupling between tectonic uplift and erosion but suggests that this coupling cannot be the sole explanation of rapid uplift in the Himalayan syntaxes.

The Tso Kar lake basin in Ladakh, northwestern Himalayas (33 180N, 78 E, 4527 m a.s.l.) is located close to the modern boundary of effective moisture transport from the Indian summer monsoon. In order to reconstruct the possible monsoonal impact on the hydrology of the lake basin during the last 15 kyr, we studied the geomorphology of the basin and combined the results with multi-proxy records ...

a r t i c l e i n f o The rapid expansion of high-spatial resolution optical sensors and imagery over the last decade presents exceptional opportunities for quantifying visible attributes of geomorphic systems. In this study, we detail a simple, robust methodology (ChanGeom) to extract continuous channel width and centerline datasets for single-thread channels using freely available high-spatia...

This paper introduces a new method for three-dimensional (3D) coastal geomorphology reconstruction using differential synthetic aperture interferometry (DInSAR). The new method is based on an integration between fuzzy B-spline algorithm and DInSAR method. DInSAR algorithm is involved two parts: (i) 3D map simulation which is based on interferogram simulation and (ii) satellite orbit parameters....

Tectonic processes are major factors controlling landform development in tectonically active areas. In order to evaluate quantitative measurement of tectonic activities in the Alamarvdasht basin in the south of Iran, six different morphological indices including stream-gradient index (SL), drainage basin asymmetry (Af), hypsometric integral (Hi), valley floor width-valley height ratio (Vf), dra...

Geomorphology is the study of Earth’s landforms and the processes that shape them. From its beginnings, geomorphology has embraced a historical approach to understanding landforms; the concept of evolving landforms is firmly ingrained in geomorphic thought. Modern process geomorphologists use the term landscape evolution to describe the interactions between form and process that are played out ...

We apply a deep learning model to segment and identify rock characteristics based on Structure-from-Motion orthomap digital elevation of rocky fault scarp in the Volcanic Tablelands, Eastern California, USA. By post-processing results, we build semantic map analyse trait distributions. The resulting contains nearly 230 000 rocks with effective diameters ranging from 2 250 cm. Rock distributions...

Steep topographic reliefs and heavy vegetation severely limit visibility when examining geological structures and surface deformations in the field or when detecting these features with traditional approaches, such as aerial photography and satellite imagery. However, a light detection and ranging (LiDAR)-derived digital elevation model (DEM), which is directly related to the bare ground surfac...
