Field sampling design and spatial scale in habitat-hydraulic modelling: comparison of three models
International audience Habitat-hydraulic models simulating habitat productive capacity for fish have met with limited success. Limitations of hydraulic modelling, particularly related to spatial scale relevant for hydraulic field data collection and model simulations, have attracted little attention...

International audience Habitat-hydraulic models simulating habitat productive capacity for fish have met with limited success. Limitations of hydraulic modelling, particularly related to spatial scale relevant for hydraulic field data collection and model simulations, have attracted little attention. The hypothesis that hydraulic field sampling procedures and modelling scale per se affect results was tested using three habitat-hydraulic models that employed the same fish habitat data and similar hydraulic models. The PHABSIM, EVHA and HABITAT habitat-hydraulic models were compared on a 5.56 km long, 12-35 m wide , river segment in newfoundland, Canada. Approaches to hydraulic data collection allowed higher spatial resolution in the EVHA and HABITAT models on selected subsegments representing habitat types (with from 12 to 14 transects per subsegment), while the PHABSIM models covered the entire segment but at lower resolution (a total of 14 transects representing four habitat types placed along the enire segment).
