资源简介:
Rainfall on 913 September 2013 triggered at least 1,138 debris flows in a 3430 km2 area of the Colorado Front Range. Most flows were triggered in response to two intense rainfall periods, one 12.5-hour-long period on 1112 September, and one 8-hour-long period on 12 September. Data in this project pertain to an area bounded by N 40.0 40.375 and W 105.25 105.625 which includes many of the areas where high concentrations of debris flows occurred. These data include a subset of a map of landslide and debris flow scarps (Coe and others, 2014) and raster grids derived from the National Elevation Dataset. These data were used to test a new, parallel implementation of the Transient Rainfall Infiltration and Grid-Based Regional Slope-Stability Model (TRIGRS, see Baum and others, 2010) for the timing and distribution of rainfall-induced shallow landslides. The data accompany an interpretive paper being reviewed for publication in the journal Environmental Modeling & Software (Alvioli and Baum, in review).

2013年9月的降雨在科罗拉多前缘(Colorado Front Range)3430平方千米的区域内至少触发了1138处泥石流。绝大多数泥石流由两场强降雨过程诱发:一场持续12.5小时的降雨过程发生于9月11日至12日,另一场持续8小时的降雨过程发生于9月12日。
本项目涉及的研究区域范围为北纬40.0°至40.375°、西经105.25°至105.625°,该区域涵盖了大量泥石流高发点位。本数据集包含滑坡与泥石流陡坎地图的子集(Coe等,2014),以及源自国家高程数据集(National Elevation Dataset)的栅格网格数据。
本数据集被用于测试一款全新的并行化瞬态降雨入渗与栅格化区域斜坡稳定性模型(Transient Rainfall Infiltration and Grid-Based Regional Slope-Stability Model,TRIGRS,参见Baum等,2010),以模拟降雨诱发浅层滑坡的发生时间与空间分布特征。
本数据集配套一篇正在《Environmental Modeling & Software》期刊审稿的阐释性论文(Alvioli与Baum,待刊)。
