Abstract
This paper describes the methodological concept for application of physical habitat models to restoration planning at a whole river scale. The design proposed here builds upon the Instream Flow Incremental Methodology but is focused at the need for man,A aging large-scale habitats and river systems. it modifies the data acquisition technique and analytical resolution of st andard approaches, changing the scale of physical parameters and biological response assessment from micro- to meso-scale. In terms of technological p rocess, a highly detailed microhabitat survey of a few, short sampling site s would be replaced by mesohabitat mapping of whole-river sections. As with more traditional stream habitat models, the variation in the spatial distr ibution and amount of mesohabitats can provide key information on habitat q uality changes corresponding to alterations in flow, channel changes, and s tream improvement measures. However, the scale of simulations more closely matches restoration and system analyses, because it provides a solid base f or quantitative assessment and simulation of habitat conditions for the who le stream.
