Stream Restoration by Fluvial Biogeomorphic Succession: Applications of a self-forming stream design concept in Ohio.

The self-forming stream design approach was evaluated on nine reaches in Ohio that are typical of stream restoration projects in the region. The aim of self-forming stream restoration is to construct a channel form that is consistent with an intermediate stage of channel evolution models with the expectation that subsequent successional stages and beneficial processes will follow, and conclude with a stream that is hydrogeomorphically fit to its catchment. This essentially entailed the construction of a roughly planar surface with a stable longitudinal slope and sufficient width to allow a depositional response. Repeated geomorphological surveys were conducted to track change through time.
