论文题目:Inverted channels and buried channels in the Qaidam Basin, NW China: Insight from remote sensing and numerical simulation
论文摘要:Fluvial channels are extensively identified on the Earth and other terrestrial planets. Two different types of fluvial channels are found in the Qaidam Basin, NW China. Different channels are indicators of different paleo-environments with the complex fluvial and climate history. The buried channel is formed by aeolian deposition process. The inverted channel is caused by differential wind erosion. In this paper, first we propose a workflow to detect the two channels using Sentinel-1 Synthetic Aperture Radar (SAR) datasets and multi-source datasets on Google Earth Engine, then we propose a numerical model to simulate the evolution of the inverted channel. Due to the different backscattering coefficient of the ground surface materials, we set a threshold of the backscattering coefficient as -18.5 dB to distinguish the two channel and surrounding features. Canny edge detection is used to delineate the inverted channels and buried channels. Based on the distribution and morphological characteristics of the two channels and previous studies on sediment chronology in the Qaidam Basin, we propose the evolution process of the channels and climate change since the Holocene. The inverted channel might form during the hyper-arid period of the early Holocene since 12.6±0.8 ka. The buried channel is formed during the period of the sand accumulation since 4-3 ka.
