Abstract
Bank erosion is a natural process that may be considered beneficial or detrimental, depending upon the associated environmental or socioenvironmental concerns. Stream channels respond to inputs of water, sediment and woody debris, forming dynamic links between hillslopes and riparian areas in the watershed. Anthropogenic activities such as forest harvesting may affect channel processes through changes in the intensity, timing of delivery and total yield of sediment and water from the hillslopes. Impacts to riparian vegetation from streamside forest harvesting, farming and ranching practices have further altered sediment loading and woody debris structure within channels. Bank erosion may lead to a degradation of fish habitat through loss of protective cover, reduced channel depths, increased stream temperatures, infilled pools and smothered spawning gravels. This chapter describes the rehabilitation of stream banks that have been impacted by historical logging practices. it includes a section on the assessment of a site-specific need to stabilize eroding stream banks, and describes the most suitable stabilization techniques as a function of the fluvial environment. Central to the techniques presented is the need for a multiple objective treatment approach that simultaneously addresses bank stabilization and fish habitat requirements.
