“…Zhao et al [101] argued that the incision rates in the upper Liupanshan mountains, located at the northern margin of the Qianhe Basin and the southwest margin of the Ordos Block, range from 0.37 to 1.13 m/kyr. All of these results indicate a decreasing trend in the rate of incision from the margin to the central area, obeying the characteristic of the "high-lowhigh" pattern discussed by Gao et al [100] and the changes in the topography and the gradients of inclines in the area. Moreover, the changes in landform have been confirmed unlikely to have been caused by the climate [9], but may limit the erosion rates, rendering the rate of erosion lower than that of uplift.…”

Moreover, they also measured the age and height of the terraces running alongside the Upper Weihe River in the Sanyangchuan Basin, and found that the incision rates ranged from 0.21 to 1.03 m/kyr [100].

Evaluating the Vertical Accuracy of DEM Generated from ZiYuan-3 Stereo Images in Understanding the Tectonic Morphology of the Qianhe Basin, China

Currently available high-resolution digital elevation model (DEM) is not particularly useful to geologists for understanding the long-term changes in fluvial landforms induced by tectonic uplift, although DEMs that are generated from satellite stereo images such as the ZiYuan-3 (ZY3) satellite include characteristics with significant coverage and rapid acquisition. Since an ongoing analysis of fluvial systems is lacking, the ZY3 DEM was generated from block adjustment to describe the mountainous area of the Qianhe Basin that have been induced by tectonic uplift. Moreover, we evaluated the overall elevation difference in ZY3 DEM, Shuttle Radar Topography Mission (1″ × 1″) (SRTM1), and Reflection Radiometer Global Digital Elevation Model (ASTER GDEM) by using the Ice Cloud and Land Elevation Satellite/Geoscience Laser Altimeter (ICESat/GLAH14) point cloud and a DEM of 1:50,000 scale. The values of the root mean square error (RMSE) of the elevation difference for ZY3 DEM were 9.31 and 9.71 m, respectively, and are in good agreement with SRTM1. The river long profiles and terrace heights were also extracted to compare the differences in channel steepness and the incision rates with SRTM1 and ASTER GDEM. Our results prove that ZY3 DEM would be a good alternative to SRTM1 in achieving the 1:50,000 scale for DEM products in China, while ASTER GDEM is unsuitable for extracting river longitudinal profiles. In addition, the northern and southern river incision rates were estimated using the ages and heights of river terraces, demonstrating a range from 0.12–0.45 to 0.10–0.33 m/kyr, respectively. Collectively, these findings suggest that ZY3 DEM is capable of estimating tectonic geomorphological features and has the potential for analyzing the continuous evolutionary response of a landscape to changes in climate and tectonics.

“…A fluvial terrace is an abandoned floodplain currently separated from the modern floodplain, or from a lower fluvial terrace, by a steeper slope, or scarp. Valleys often contain flights of multiple terraces that record the response of the fluvial system to environmental change in the watershed (Merritts et al, 1994;Blum and T€ ornqvist, 2000;Gibbard and Lewin, 2009;Pan et al, 2003Pan et al, , 2009Bridgland and Westaway, 2014;Counts et al, 2015;Bridgland et al, 2017;Gao et al, 2017;Silva et al, 2017). Fluvial systems evolve under forcing factors such as the topographic and lithological attributes of watersheds, climatic change (which affects the ratio of water and sediment inputs from the slope system, and thus stream/ resisting power) and base-level changes d whether driven by tectonics or eustasy (Leopold et al, 1964;Schumm, 1969Schumm, , 19772007;Bull, 1991).…”

The 120 km-longTêt River flows out of the Pyrenees to the Mediterranean. By displaying a mappable sequence of Quaternary alluvial units between the Pleistocene frontal moraines of the high range and the offshore sedimentary depocentres, its 1400 km 2 watershed is well suited to quantifying gradients of topographic uplift. Five main generations of terrace treads had previously been inferred from constrasts in regolith weathering features, but here we present the first radiometric age constraints based on 15 ESR sediment burial ages covering the full sequence, and 3 vertical TCN age profiles restricted to three midsequence terraces. Analytically robust results were obtained for the oldest and uppermost terrace T5 (ESR age: 1099 ± 179 ka), for T3b (ESR age: 374 ± 47 ka,~MIS 10), and for T2 (ESR age: 174 ± 44 ka,~MIS 6). These results are consistent with the contrasts in weathering grade of the deposits. The TCN profiles only yielded minimum exposure ages but provided precise post-depositional denudation rates for the fluvial terrace treads. The land-to-sea geometry of the chronosequence also provided clues about valley incision rates in response to topographic uplift during the last~1 Ma. Based on a critical review of similar data obtained for other Mediterranean and Atlantic watersheds in the Pyrenees, the full regional correlation reveals that post-orogenic topographic uplift was substantial and relatively uniform throughout the entire mountain range. Patterns and magnitudes suggest a shared, probably subcrustal driving mechanism of Neogene and Quaternary mountain growth, with only subsidiary influence from isostasy, and climatic forcing.

“…Many regional and global syntheses of fluvial processes have shown that, in the long term (i.e., 10-1000 kyr), fluvial activities are driven by the orbital-scale climate fluctuations overprinted on to the effects of tectonic uplift [2,3,6,[14][15][16]. However, in the short term (i.e., 1-10 kyr), there remains considerable debate about how rivers respond to climate change [4,[17][18][19].…”

Research into river processes in different climatic and geomorphic areas is vital for a clearer understanding of the non-linear responses of rivers to climate change. The Huaihe River (HHR) Basin, located in China’s North–South Transition Zone (NSTZ), provides an ideal environment in which to explore river responses to climate change within a humid/semi-humid transitional area. Based on optically stimulated luminescence (OSL) and 14C dating, combined with sedimentary stratigraphic analyses, we reconstructed the river processes of three sedimentary sequences in the upper HHR since the Late Quaternary. Our results showed that the upper HHR was characterized by aggrading meandering channels from the Last Glacial Maximum (LGM) to 0.5 ka, and an aggrading wandering channel from 0.2 ka to the present. Two periods of downcutting occurred during 5.8–3.0 and 0.5–0.2 ka, respectively. The river incision is potentially linked to changes in the climate during the Mid–Late Holocene transition and the Little Ice Age (LIA). However, there have been no marked changes in channel patterns in the upper HHR since the LGM. This phenomenon reflects the influence of vegetation on channel patterns during climate change. Our results showed that the fluvial processes in different climatic and geomorphic areas are controlled by the local hydroclimatic regime.
