RAPID: An Integrated Study of Post-fire Wind and Water Erosion in Western Rangelands

摘要：该项目的非技术描述，解释了该项目的意义和重要性美国西部野火的环境和人类成本是巨大的，并且随着人口向远离城市中心的地区增长，它们正在增加。这些火灾以多种方式影响景观，包括风和水的侵蚀增加。该项目将利用现有的监测网络，雷诺兹溪临界区观测站，来检查2015年8月爱达荷州西南部苏打大火后的粉尘产生和侵蚀率。这些新数据可以与风暴前的测量数据进行比较，以便评估火灾对陆地表面的影响程度，这些影响可以推广到许多其他火灾易发地区。该项目的技术描述该RAPID项目将整合爱达荷州和俄勒冈州边境发生大型牧场火灾后火灾后风和水侵蚀的影响。苏打大火最近烧毁了俄勒冈州爱达荷州边境超过28万英亩的牧场，包括雷诺兹溪临界区天文台（CZO）约25%的分水岭。火灾产生的烟尘为博伊西和其他地区社区带来了沙尘暴和危险的空气质量状况。预计未来几个月，风和水的进一步侵蚀将会增加。该研究将测量该流域火灾后沉积物和碳的侵蚀。雷诺兹河实验流域的大量监测设备，加上与联邦合作者正在进行的协同研究，提供了一个机会来研究风和水在从山坡到区域尺度产生火灾后侵蚀中的双重作用。

ABSTRACTA non-technical description of the project, which explains the project's significance and importanceThe environmental and human costs of wildfires in the western United States are great and they are increasing as populations grow into areas farther away from urban centers. These fires affect the landscape in many ways, including an increase in erosion by both wind and water. This project will take advantage of an existing monitoring network, the Reynolds Creek Critical Zone Observatory, to examine dust generation and erosion rates following the Soda fire in southwestern Idaho in August, 2015. These new data can be compared to the pre-storm measurements in order to evaluate the extent of fire effects on the land surface that can be generalized to many other fire-prone regions. A technical description of the projectThis RAPID project will integrate the influence of post- fire wind and water erosion following a large rangeland fire on the Idaho-Oregon border. The Soda fire recently burned over 280,000 acres of rangelands along the Oregon Idaho border, including ~25% of the watershed in the Reynolds Creek Critical Zone Observatory (CZO). Smoke and dust from this fire produced dust storms and hazardous air quality conditions for Boise and other regional communities. Further erosion by both wind and water is expected to increase in the coming months. The research will measure post-fire erosion of sediment and carbon in this watershed. An extensive array of monitoring equipment at the Reynolds Creek Experimental Watershed, plus ongoing synergistic studies with federal collaborators, provide an opportunity to examine the dual roles of wind and water in generating post-fire erosion from the hillslope to the regional scale.
