Glacial lake outburst flood simulations for Poiqu Basin

This zip file contains simulation results (conducted with r.avaflow) for large ice/rock avalanche triggered glacial lake outburst floods in the Poiqu Basin. These results are presented in the paper by Allen et al. 2022, Glacial lake outburst flood hazard under current and future conditions: worst-case scenarios in a transboundary Himalayan basin, Natural Hazards and Earth System Science, https://doi.org/10.5194/nhess-22-1-2022. Raster files of flow height are provided for simulations of Galongco, Jialongco (for the lake volume in 2019, and for the reduced lake volume in 2021), and for the Future Lake. An Excel file provides a time series of flow height and discharge at cross sections measured at the outlet of the lake (moraine), in the town of Nyalam, and in Zhangmu for each simulation.本压缩包包含波曲流域内由大型冰崩与岩崩触发的冰川湖溃决洪水的模拟结果，所有模拟均采用r.avaflow软件完成。该数据集对应Allen等人2022年发表于《Natural Hazards and Earth System Science》（《自然灾害与地球系统科学》）的论文《当前与未来情景下的冰川湖溃决洪水风险：喜马拉雅跨界流域的极端情景》，对应的DOI链接为https://doi.org/10.5194/nhess-22-1-2022。 本次提供的流动高度栅格文件覆盖了Galongco（嘎隆错）、Jialongco（甲隆错，包含2019年湖体容积场景及2021年缩减湖体容积场景）以及Future Lake（未来湖体）的模拟场景。 此外，配套Excel文件涵盖了所有模拟场景中，湖泊冰碛坝出口处、聂拉木镇境内以及樟木境内的监测断面处的流动高度与流量时间序列数据。
