Sediment accumulations and field-saturated hydraulic conductivity time series following the 2017 Nuns and Tubbs wildfires, Napa and Sonoma Counties, CA, USA

This dataset comprises repeat surveys of field-saturated hydraulic conductivity and sorptivity following the October 2017 Nuns and Tubbs wildfires as part of an effort to document soil-hydraulic recovery. A summary table includes associated physiographic properties for each site, including: pre-burn vegetation, lithology, soil burn severity, location, soil texture, and associated van Genuchten parameters determined using Carsel and Parrish (1988). Soil-hydraulic properties were calculated using the model of Zhang (1997) and Vandervaere et al. (2000). We separately include the raw cumulative infiltration measurements used for the calculation of soil-hydraulic properties. Lastly, this dataset includes a survey of dry ravel accumulations measured in July 2019 in heavily burned watershed within Mark West Creek Regional Park and Open Space Preserve. Dry ravel accumulations were measured through excavating sediment piles along road cuts and identifying the thickness of post-fire sediment layers.

本数据集为记录2017年10月努恩塔布斯（Nuns and Tubbs）野火后土壤水力恢复状况，针对田间饱和导水率与吸渗率开展的重复监测数据集。数据集附带的汇总表包含各监测点位的相关地貌属性，具体包括：火前植被类型、岩性、土壤火烧烈度、点位位置、土壤质地，以及基于Carsel与Parrish（1988）方法确定的范·吉努赫滕（van Genuchten）参数。土壤水力属性通过Zhang（1997）与Vandervaere等人（2000）提出的模型计算得到。本数据集同时包含用于土壤水力属性计算的原始累积入渗量实测数据。此外，本数据集还包含2019年7月在马克西克里克区域公园及开放空间保护区（Mark West Creek Regional Park and Open Space Preserve）重度火烧流域内开展的干碎屑堆积量调查数据。干碎屑堆积量通过沿路堑开挖沉积物堆并辨识火烧后沉积物层厚度的方法测定。
