This paper demonstrates the use of a multiplex habitat model for flow management criteria development compliant with the natural flow paradigm using the Upper Delaware River (NY/PA—USA) as an example. The goal of this study was to identify strategies to protect and support the recovery of the dwarf wedgemussel populations in the mainstem Delaware River. We quantified potential habitat, developed instreamflow recovery scenarios and modelled the scenario outcomes. Mesohabitat simulation model and River2D have been used to allow the transfer of suitability criteria between scales. Habitat time series were investigated with the help of the uniform continuous under threshold technique to establish natural habitat stressor thresholds.
