Runoff and erosion from small forest watersheds on the Boise Basin Experimental Forest

By September of 2004, ten small watersheds ranging in size from 0.9 to 12.2 hectares were installed in the Boise Basin Experimental Forest (BBEF) in east/central Idaho approximately 48 kilometers (30 miles) northeast of Boise, Idaho and 5 kilometers (3 miles) southeast of the village Idaho City, Idaho. The long term objective of the study was to compare impacts of different management activities, but in the early years, none of the watersheds received any management treatments or natural disturbances. This data publication contains daily temperature, relative humidity, precipitation, wind speed, and runoff measurements recorded from 2004 through 2010. Also included are soil loss and ground cover data collected during this same time period. Additionally, a shaded relief map of the hillslope and raster image file of the BBEF are included, along with shapefiles providing the boundaries of each watershed. Watershed treatment information and timing is also provided, which includes details denoting that due to insufficient funds four of the ten watersheds scheduled for treatment were not treated. Two were designated as controls and the remaining four watersheds were burned in 2008 two of which were salvaged logged the following year.
The purpose of this study is to measure the watershed impacts of current forest fuel management practices, simulated wildfire, and to present the runoff and erosion rates observed on these watersheds prior to and following any treatment in order to evaluate natural variability in small watershed studies.
For additional information regarding this study and the pre- and post-fire analyses of these data see Elliot and Glaza (2007 and 2009), and analysis evaluating the topographic features of post-fire mineral soil can be found in Dobre et al. (2014).

2004年9月，研究人员于爱达荷州东部/中部的博伊西流域实验林（Boise Basin Experimental Forest, BBEF）布设了10个面积介于0.9至12.2公顷的小流域。该实验林地处爱达荷州博伊西东北约48公里（30英里）处，距爱达荷城村镇东南5公里（3英里）。本研究的长期目标为对比不同营林活动的影响，但实验初期所有小流域均未接受任何营林处理或自然干扰。本数据集包含2004年至2010年间记录的逐日气温、相对湿度、降水量、风速与径流量观测数据，同期采集的土壤流失量与地表覆盖数据亦纳入其中。此外，数据集还提供了该实验林山坡的山体阴影晕渲图与实验林栅格图像文件，以及标注各小流域边界的形状文件（shapefile）。同时附带流域处理信息与实施时序，其中明确说明：因资金不足，原定开展处理的10个小流域中有4个未实施处理。其中2个被设为对照样区，剩余4个于2008年完成火烧处理，其中2个在次年开展了灾后打捞采伐。
本研究旨在量化当前森林燃料管理措施、模拟野火对流域的影响，并呈现各小流域在处理前后的径流量与侵蚀速率，以此评估小流域研究中的自然变异性。
如需了解本研究及本数据集的火前与火后分析详情，可参阅Elliot与Glaza（2007、2009）的相关文献；关于火烧后矿质土壤地形特征的分析，请参见Dobre等人（2014）的研究成果。
本数据集于2021年3月31日正式发布，2021年4月15日新增了元数据补充内容。
