Abstract
The California High-Speed Rail is currently planning a rail corridor through the San Gabriel Mountains. The alignment will require tunnels up to approximately 600 m deep and crossing through the San Gabriel Mountains in the SR 14 area. This study utilized repeated optical and infrared unmanned aerial vehicle (UAV) aerial imagery to document the baseline environmental conditions overlying one of the future high-speed rail tunnels. Images provide vegetation and soil moisture patterns along the surface route of the corridor for future comparison when the tunneling segments are bored. Analysis of reflectance data revealed subsurface water flow in the Bear Creek-Sand Canyon Creek Study Area. Using UAVs is considered an effective new tool to detect large-scale and discrete environmental conditions, perhaps undocumented or unobservable, via standard mapping tools. Setting detailed baseline conditions is important to identify changes that may occur because of future tunneling.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
