WebWhereas the natural flow para- digm (Poff et al., 1997) assumes that channel form is substantially adjusted to flow, morphology of an engi- neered river can be practically independent of flow. This limits the efficacy of restoring the flow regime alone. WebSep 1, 2013 · The implementation of environmental flow regimes offers a promising means to ...
