项目摘要
Steps and pools are characteristic bedforms that dominate the channel morphology of steep mountain streams, regulating the flow and sediment dynamics feeding into lowland rivers and larger water bodies. In summer of 2012, several catastrophic wildfires spread across the Rocky Mountains of Colorado and burned numerous watersheds containing step-pool channels. These events provide opportunities to monitor the impacts of wildfire as a major disturbance on step-pool streams, and to ultimately develop predictive understanding of the resilience and potential recovery of such systems. This project seeks to quickly establish baseline conditions in step-pool channels before significant changes occur in response to the Waldo Canyon Fire. The Waldo Canyon Fire started on 23 June 2012 and was fully contained on 10 July 2012. It burned 18,247 acres of an area just northwest of the city of Colorado Springs, mostly on national forest land. Channel conditions in burned step-pool streams within the Pike National Forest will be documented at selected reaches. Temporary benchmarks installed in the study sites will provide bed elevations. Physical measurements include longitudinal profiles, cross-sections at pools, suspended sediment, and turbidity. Benthic macroinvertebrate samples will also be collected for analysis of wildfire impacts on benthic communities, particularly in relation to the impacts of changes in sediment regime in the streams.The project will generate information that can be used by environmental managers who manage water resources for communities such as Colorado Springs while also working to protect residents from flood and sediment hazards. Because step-pool streams are important habitats for many sensitive aquatic species, results of this study are also expected to have implications for ecological management. The project will engage graduate and undergraduate students, and develop a collaboration with the US Geological Survey.
阶梯和水池是独特的河床形式,主导着陡峭的山间溪流的河道形态,调节流入低地河流和较大水体的水流和泥沙动力学。2012年夏天,几场灾难性的野火席卷了科罗拉多州的落基山脉,烧毁了许多包含台阶水道的分水岭。这些活动提供了机会,以监测野火对梯级池溪流的主要干扰的影响,并最终发展对这类系统的复原力和潜在恢复的预测性了解。该项目寻求在沃尔多峡谷火灾发生重大变化之前,快速建立阶梯水池水道的基线条件。沃尔多峡谷大火于2012年6月23日开始起火,并于2012年7月10日完全得到控制。大火烧毁了科罗拉多州斯普林斯市西北部18247英亩的土地,大部分是国家林地。将在选定的范围内记录派克国家森林内燃烧的阶梯水池溪流的河道状况。安装在研究地点的临时基准将提供床位高程。物理测量包括纵向剖面、水池横截面、悬浮泥沙和浊度。还将收集底栖大型无脊椎动物样本,以分析野火对底栖群落的影响,特别是与河流沉积物状况变化的影响有关的影响。该项目将产生可供环境管理人员使用的信息,他们在为科罗拉多斯普林斯等社区管理水资源的同时,还致力于保护居民免受洪水和泥沙危害。由于阶梯塘溪流是许多敏感水生物种的重要栖息地,这项研究的结果也有望对生态管理产生影响。该项目将吸引研究生和本科生,并与美国地质调查局开展合作。
