Technical Abstract: The Stream Design Guide provides guidance for multidisciplinary teams who are planning and designing projects that are intended to control floods or sediment sources, hasten drainage, stabilize banks, improve fish habitat, or restore ecological functions and processes. This section of the guide contains information essential for successful planning, design and maintenance of stream stabilization and habitat rehabilitation structures made from fallen or harvested trees, also referred to as large woody material. Such structures include log weirs, engineered log jams, log vanes, rootwad systems, tree revetments, toe logs, and brush mattresses. These types of measures are increasingly attractive due to their relatively low cost and because large wood is an important component of stream ecosystems. Key considerations for use of large wood include habitat requirements, sediment load and type, dominant bank erosion processes, site access, and flow conveyance.
