Solifluction is one of the most widespread periglacial processes with low annual movement rates in the range of $^{-}$ millimeters to centimeters. Traditional methods to assess solifluction movement usually have low spatial resolution, which hampers our understanding of spatial movement patterns and the factors controlling them. In this study, we (a) test the applicability of unmanned aerial vehicle (UAV)-based structurefrom-motion photogrammetry in comparison to a traditional total station survey tomap surface movement of a turf-banked solifluction lobe (TBL) in the Turtmann Valley (Switzerland). We then (b) relate the detected movement patterns to potential geomorphometric, material, thermal and vegetation controls, which we assessed using geomorphic and vegetation mapping, electrical resistivity surveys and temperature loggers. Our results show that (a) UAV-based mapping can detect solifluction movement with high spatial resolution (one point per m$^{2}$, total > 900 points) and rates and patterns consistent with a total station survey, but requires careful measurement set-up and analysis; and (b) movement rates differ between lobe tread, riser and a ridge feature. Differences can be explained by heterogeneous material, geomorphometric, thermal and vegetation properties of the TBL, which promote different solifluction processes. Our study demonstrates the applicability of UAV-based mapping in solifluction research and improves our understanding of solifluction processes and landform development.

基于无人驾驶飞行器的草皮倾斜波瓣运动映射及其与材料、地貌、热和植被特性的关系

Solifluction 是最普遍的冰缘过程之一,其年移动率在 $^{-}$ 毫米到厘米的范围内。评估流动性运动的传统方法通常具有较低的空间分辨率,这阻碍了我们对空间运动模式及其控制因素的理解。在这项研究中,我们 (a) 测试了基于无人机 (UAV) 的结构运动摄影测量与传统全站仪测量相比的适用性,以绘制 Turtmann 山谷中草皮倾斜波瓣 (TBL) 的表面运动。瑞士)。然后,我们 (b) 将检测到的运动模式与潜在的地貌测量、材料、热和植被控制联系起来,我们使用地貌和植被测绘、电阻率调查和温度记录器对其进行评估。我们的结果表明 (a) 基于 UAV 的测绘可以以高空间分辨率(每 m$^{2}$ 一个点,总计 > 900 个点)以及与全站仪测量一致的速率和模式来检测流动运动,但需要仔细测量设置和分析;(b) 波瓣胎面、立管和山脊特征之间的移动率不同。差异可以通过 TBL 的异质材料、地貌测量、热和植被特性来解释,这些特性促进了不同的流动过程。我们的研究证明了基于无人机的测绘在流动研究中的适用性,并提高了我们对流动过程和地形发展的理解。900 点)和速率和模式与全站仪调查一致,但需要仔细的测量设置和分析;(b) 波瓣胎面、立管和山脊特征之间的移动率不同。差异可以通过 TBL 的异质材料、地貌测量、热和植被特性来解释,这些特性促进了不同的流动过程。我们的研究证明了基于无人机的测绘在流动研究中的适用性,并提高了我们对流动过程和地形发展的理解。900 点)和速率和模式与全站仪调查一致,但需要仔细的测量设置和分析;(b) 波瓣胎面、立管和山脊特征之间的移动率不同。差异可以通过 TBL 的异质材料、地貌测量、热和植被特性来解释,这些特性促进了不同的流动过程。我们的研究证明了基于无人机的测绘在流动研究中的适用性,并提高了我们对流动过程和地形发展的理解。促进不同的溶解过程。我们的研究证明了基于无人机的测绘在流动研究中的适用性,并提高了我们对流动过程和地形发展的理解。促进不同的溶解过程。我们的研究证明了基于无人机的测绘在流动研究中的适用性,并提高了我们对流动过程和地形发展的理解。
