Data and scripts associated with “Thresholds of Area Burned and Burn Severity for Downstream Riverine Systems to ‘Feel the Burn’”

This data package is associated with the publication “Thresholds of Area Burned and Burn Severity for Downstream Riverine Systems to ‘Feel the Burn’” submitted to Water Resources Research (Wampler et al. 2025). This study used the Soil and Water Assessment Tool (SWAT), a processed based model to explore the impacts of area burned and burn severity on streamflow, nitrate, and dissolved organic carbon (DOC) in two test basins: a semi-arid, mixed land use basin and a humid, primarily forested basin. We developed 1800 wildfire scenarios that we ran in each basin: 20 different burn extents (5 to 100% by 5%), 3 different burn severities (low, moderate, and high), and 30 different post-fire precipitation scenarios. We also ran an additional 30 scenarios associated with no wildfire for the 30 post-fire precipitation scenarios. For each scenario we were interested in the change in runoff ratio (streamflow) and average concentration and annual loads (nitrate and DOC) across the wildfire scenarios. This data package contains the data and scripts required to build SWAT models for the two test basins, create and run the wildfire scenarios, and generate the data summaries and figures used in the associated manuscript. This dataset contains (1) file-level metadata; (2) data dictionary; (3) data package readme; (4) workflow documentation; (5) a folder with model input data (“inputs”); (6) a folder with model output data (“outputs”); and (7) a folder with scripts needed to create and run the models and analyze the outputs (“scripts”). The input data folder contains the following items: (1) a DOC/wildfire module where the DOC outputs are in kilograms per time step (Wampler et al. 2023); (2) a DOC/wildfire module where the DOC outputs are in milligrams per liter; (3) a modified SWAT-CUP (https://www.2w2e.com/home/SwatCup) file with absolute parameter values; (4) a .csv file with calibrated parameter values for both models; (5) a .txt file called “model.in” with updated parameters for the DOC module; and (6) a .pdf with directions for using the wildfire module. The folder with model output data contains three subfolders: (1) “data”, which contains the processed model outputs; (2) “figures”, which contains the figures from the manuscript; and (3) “summary-outputs”, which contains summarized data used to create tables and results for the manuscript. This package contains the following file types: csv, exe, in, txt, pdf, R, png.

这个数据集包与提交至《水资源研究》（*Water Resources Research*）的出版物《下游河流系统“感知火烧”的烧损面积与火烧强度阈值》（Wampler等，2025）相关联。本研究采用基于过程的模型——土壤与水资源评估工具（Soil and Water Assessment Tool, SWAT），探究烧损面积和火烧强度对两个测试流域（一个半干旱、混合土地利用流域，另一个湿润、以森林为主的流域）的径流、硝酸盐及溶解性有机碳（dissolved organic carbon, DOC）的影响。我们开发了1800种野火情景，并在每个流域中运行：20种不同的烧损范围（5%至100%，间隔5%）、3种不同的火烧强度（低、中、高），以及30种不同的火后降水情景。本数据集包包含构建两个测试流域SWAT模型、创建和运行野火情景、生成相关手稿所用数据摘要和图表所需的数据与脚本。该数据集包含以下内容：(1) 文件级元数据；(2) 数据字典；(3) 数据集包说明文档；(4) 工作流程文档；(5) “inputs”文件夹（含模型输入数据）；(6) “outputs”文件夹（含模型输出数据）；(7) “scripts”文件夹（含创建和运行模型、分析输出结果所需的脚本）。输入数据文件夹包含以下项目：(1) DOC/野火模块（DOC输出单位为千克/时间步）；(2) DOC/野火模块（DOC输出单位为毫克/升）；(3) 经修改的SWAT-CUP（https://www.2w2e.com/home/SwatCup）文件（含绝对参数值）；(4) 包含两个模型校准参数值的.csv文件；(5) 名为“model.in”的.txt文件（含DOC模块的更新参数）；(6) 野火模块使用说明.pdf文件。模型输出数据文件夹包含三个子文件夹：(1) “data”（含处理后的模型输出结果）；(2) “figures”（含手稿中的图表）；(3) “summary-outputs”（含用于创建手稿表格和结果的汇总数据）。本数据集包包含以下文件类型：csv、exe、in、txt、pdf、R、png。
