Contrary to form-based restoration, which consists of improving a streams conditions by modifying its structure, process-based restoration focuses on restoring the hydrological and geomorphological processes (or functions) that contribute to the streams alluvial and ecological dynamics. This type of stream restoration has gained in popularity since the mid-1990s, as a more ecosystem-centered approach. Process-based restoration includes restoring lateral connectivity (between the stream and its floodplain), longitudinal connectivity (along the stream) and water and/or sediment fluxes, which might be impacted by hydro-power dams, grade control structures, erosion control structures and flood protection structures. Valley Floor Resetting epitomises process-based restoration by infilling the river channel and allowing the stream to carve its anastomosed channel anew, matching [http://stagezeroriverrestoration.com/index.html Stage Zero] on the Stream Evolution Model. In general, process-based restoration aims to maximize the resilience of the system and minimize maintenance requirements. In some instances, form-based restoration methods might be coupled with process-based restoration to restore key structures and achieve quicker results while waiting for restored processes to ensure adequate conditions in the long term.
