Map and model input and output data covering N 40.0° – 40.375° and W 105.25° – 105.625° in the northern Colorado Front Range for analysis of debris flow initiation resulting from the storm of September 9 – 13, 2013

Rainfall on 9–13 September 2013 triggered at least 1,138 debris flows in a 3430 km 2 area of the Colorado Front Range. Most flows were triggered in response to two intense rainfall periods, one 12.5-hour-long period on 11–12 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 published in the journal Environmental Modeling & Software (Alvioli and Baum,2016)

2013年9月9日至13日的降雨在面积达3430平方千米的科罗拉多前缘（Colorado Front Range）区域内，诱发了至少1138处碎屑流（debris flow）。多数碎屑流由两段强降雨过程诱发：其一为9月11日至12日持续12.5小时的降雨时段，其二为9月12日持续8小时的降雨时段。本项目所用数据的研究区域范围为北纬40.0°~40.375°、西经105.25°~105.625°，该区域涵盖了多处碎屑流高密度分布的地块。本数据集包含滑坡与碎屑流陡崖图（Coe等，2014）的子集，以及源自国家高程数据集（National Elevation Dataset）的栅格格网数据。本数据集被用于测试一款全新的并行化瞬态降雨入渗与基于格网的区域边坡稳定性模型（Transient Rainfall Infiltration and Grid-Based Regional Slope-Stability Model，TRIGRS，详见Baum等，2010），以验证其在降雨诱发浅层滑坡的发生时间与分布规律模拟方面的性能。本数据集与发表于《Environmental Modeling & Software》（环境建模与软件）期刊的阐释性论文（Alvioli与Baum，2016）配套发布。
