There are several hydraulic submodels that can be used with IFIM. These include IFG4, WSP and MANSQ. We have tailored our field data collection to allow the use of any of these models. The 2001 IFIM data collection included several steps: study segment location, habitat mapping, transect placement and data collection. The site specific procedures at each site were as follows: i • Locate study sites using topographic maps, landowner information and professional judgment. • Percentage of each habitat type was calculated from the mapped data. '? • Transects were placed in all habitats that represent over 5 % of the total available habitat. The number of transects placed in each habitat type depended on the physical and hydraulic features of each habitat type. Transects were placed in homogeneous habitat types. Additional hydraulic control transects will be placed by professional judgment at pool-riffle interfaces. The main criteria for transect selection were those listed in Bovee (1982). We further refined the transect selection with use of the habitat mapping approach that is now the preferred field methodology (Bovee 1989). i • For each set of transects in each habitat type the following survey data was collected: Ground survey to establish horizontal reference points, distance between transects, field notes with reference to general habitat and stream conditions in the transect areas, reference photos for the habitat and for each I transect within the habitat type. I • Transect specific data included: stream bed profile, mean column velocity at selected locations (verticals) along the transect line, visual estimates of dominant and subdominant substrate size and percent embeddedness, and percent cover.
