Zhiwei, Zhou; Liming, Jiang; Liu, Lin; Wang, Hansheng; Zhang, Tingjun: Rapid development of permafrost thermokarst landforms detected by repeated Unmanned Aerial Vehicle surveys in the northeastern Qinghai-Tibetan Plateau [dataset]. PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.896733 (dataset in review)
Abstract:
Using this dataset, we investigated sinkhole, thermal erosion gullies and slump-gully-complex three types of hillslope process thermokarst landforms by differencing high-resolution digital terrain models (DSMs) acquired by Unmanned Aerial Vehicle in 2016 and 2017 summers. Different development patterns are observed in these three types of thermokarst landforms: the sinkhole presents up to -5 m/year subsidence rate, the erosion gully shows up to 15 m/year headwall retreat rate, while the subsidence and headwall retreat rate of slump-gully-complex falls in between of the other two types.
