The University of California at Santa Barbara maintains a field station in the eastern Sierra Nevada mountains for research and teaching in the field sciences. The Sierra Nevada Aquatic Research Laboratory (SNARL) serves as a base for many scientists working in east-central California and western Nevada. In addition, SNARL protects a variety of terrestrial and freshwater habitats for teaching and research use. This project will provide funds to construct fifteen medium- sized experimental stream channels to augment the existing stream and pond system at SNARL. The new channels will fill an important gap in the scale of experimental units available at SNARL, which currently has only small laboratory and field channels and a series of large field channels which were formed by division of an existing natural stream. The new, medium-sized field channels will allow investigators to examine the effects of spatial scale on the outcomes of experimental manipulations. The channels will simulate the physical, chemical and biological characteristics of natural streams while providing sufficient replication for rigorous experimental designs. Although the existing stream channels at SNARL do not provide sufficient replication for most experiments, they are still a realistic and important component of the battery of experimental units at the site. Therefore, the project also provides funds to repair the concrete control structures on the existing experimental stream system.

加利福尼亚大学圣塔芭芭拉分校在内华达山脉东部维持一个野外站，以在现场科学的研究和教学。 内华达山脉水上研究实验室（SNARL）是许多在加利福尼亚东部和内华达州西部工作的科学家的基础。 此外，SNARL保护了各种陆地和淡水栖息地，用于教学和研究。 该项目将提供资金来构建15个中型实验流通道，以增强SNARL现有的流和池塘系统。 新渠道将填补SNARL可用实验单元规模的重要空白，SNARL目前只有小实验室和现场通道以及一系列通过现有自然流的划分形成的大型野外通道。 新的，中型的野外通道将允许研究人员检查空间量表对实验操作结果的影响。 这些通道将模拟自然流的物理，化学和生物学特征，同时为严格的实验设计提供足够的复制。 尽管SNARL的现有流通道无法为大多数实验提供足够的复制，但它们仍然是现场实验单元电池中现实而重要的组成部分。 因此，该项目还提供资金来修复现有实验流系统上的混凝土控制结构。
