Enhancing the Identification and Mapping of Fluvial Terraces Combining Geomorphological Field Survey with Land-Surface Quantitative Analysis

Geosciences, 2022
A methodological approach to refining the identification and mapping of fluvial terraces has been applied, combining geomorphological field surveys with the computation and assessment of different morphometric parameters (local, statistical, and object ...

Features of terraces and the incision rate along the lower reaches of the Yarlung Zangbo River east of Namche Barwa: Constraints on tectonic uplift

Open Geosciences, 2020
Along the lower reaches of the Yarlung Zangbo River, scattered alluvium sections appear on T1 and T2 terraces. The alluvial deposits on the T1 terrace in Linduo and Ximogou and the T2 terrace in Guoguotang are composed principally of coarse-grained sand ...

Late Quaternary Drainage Rearrangement Prevents the Vegetation Development in the La Tatacoa Intermontane Basin of the Colombian Andes

Frontiers in Earth Science, 2022
The Tatacoa Desert (TD) is a Cenozoic basin between the Central and Eastern Cordilleras in the southern Colombian Andes. Its sparse vegetation and Badlands morphology resemble a semi-arid environment, despite receiving ∼1,300 mm of mean annual ...

Ostracode-based aminostratigraphy and aminochronology of a tufa system in central Spain [PDF]

, 2005
In the Priego area, central Spain, extensive tufa deposits are located in three small tributaries located at the head of the 1000 kmlong Tagus River. The deposits are originated after karst-origin running waters emerged from the confines of the canyons ...

On the potential for regolith control of fluvial terrace formation in semi-arid escarpments [PDF]

Earth Surface Dynamics, 2016
Cut–fill terraces occur throughout the western Andes, where they have been associated with pluvial episodes on the Altiplano. The mechanism relating increased rainfall to sedimentation is, however, not well understood. Here, we apply a hillslope sediment

Cerna River terraces between Bãile Herculane and Orsova [PDF]

Annals of the University of Bucharest: Geography Series, 2017
This study displays a detailed analysis of Cerna river terraces along its final 20 km (its lower reach). The main working method was the field charting during a number of campaigns. The starting point were previous studies concerning Cerna river Valley,

Nature Does the Averaging—In-Situ Produced ¹⁰Be, ²¹Ne, and ²⁶Al in a Very Young River Terrace

Geosciences, 2020
The concentrations of long-lived in-situ produced cosmogenic nuclides (10Be, 21Ne, 26Al) in quartz obtained from a very recent (~200 a; based on 14C data on organic material) terrace of the Swakop River in Namibia are nearly constant throughout a 322 cm ...

The Response of the Rivers of NW Greece to Late Quaternary Neotectonics, as Interpreted from Detrital Petrology

Geosciences, 2022
The modern drainage systems of the fold and thrust belt of the external Hellenide orogen of NW Greece are principally orogen-parallel. Late Quaternary changes in river courses have resulted from neotectonic deformation associated with the Katouna–Stamna ...

Millennial slip rate of the Longitudinal Valley fault from river terraces: Implications for convergence across the active suture of eastern Taiwan [PDF]

, 2006
The Longitudinal Valley fault is a key element in the active tectonics of Taiwan. It is the principal structure accommodating convergence across one of the two active sutures of the Taiwan orogeny.

Regional fluvial geomorphic index and terrace downcutting process in the southern section of Lishi fault in Shanxi Province and their tectonic significance

地震科学进展
Based on digital elevation model (DEM), field river terrace survey and optical stimulated luminescence dating (OSL) dating, the slope, relief degree of land surface (RDLS), hypsometric integral (HI) and channel steepness index (Ksn) of the southern ...
