+ | ===== Specificities ===== | ||
+ | |||
+ | ==== Estimhab ==== | ||
+ | |||
+ | === Biological validity rangeUnlike other statistical software, the list of modeled taxa is fixed. Estimhab allows habitat simulations by species/ | ||
+ | |||
+ | The European species currently taken into account are: TRF = adult and juvenile Fario trout (the simulations for juvenile trout remain valid for fry); BAF = adult river barbel; CHA = adult sculpin; GOU = adult gudgeon; LOF = adult stone loach; VAI = adult minnow; SAT = Atlantic salmon (alevin and juvenile); OMB = grayling (fry, juvenile, adult). | ||
+ | |||
+ | Guilds are groups of species/ | ||
+ | Guild ' | ||
+ | Guild ‘midstream’: | ||
+ | (this guild is considered appropriate for nase, toxostome, dace, grayling) | ||
+ | Guild ‘pool’: eel, pumpkinseed, | ||
+ | Guild ‘bank’: gudgeon, blageon <8cm, chub <17cm, minnow | ||
+ | |||
+ | The ' | ||
+ | |||
+ | All the biological models that were used to build Estimhab are now documented in HABBY | ||
+ | HABBY\biology\models\France\fish\Irstea Former Cemagref | ||
+ | |||
+ | === Physical range of validity === | ||
+ | |||
+ | Estimhab can be used in rivers with temperate climates with a natural or slightly modified morphology (the flow rate can be modified), with a slope < 5%. | ||
+ | |||
+ | Simulations by species (except those of SAT and OMB) are quite comparable to those of EVHA (>80% variance in explained habitat value) in a range of rivers whose hydrological and hydraulic characteristics are below: | ||
+ | |||
+ | ^ Reach characteristics ^ Minimum ^ Maximum ^ | ||
+ | | Median discharge Q50 (m3/s) | 0.20 | 13.10 | | ||
+ | | Width at Q50 (m) | 5.15 | 39.05 | | ||
+ | | Depth at Q50 (m) | 0.18 | 1.45 | | ||
+ | | Substrate D50 (m) | 0.02 | 0.64 | | ||
+ | |||
+ | Simulations by guilds, (plus those for SAT and OMB) were comparable to those of EVHA in a wider range of rivers : | ||
+ | |||
+ | ^ Reach characteristics ^ Minimum ^ Maximum ^ | ||
+ | | Median discharge Q50 (m3/s) | 1.00 | 152.00 | | ||
+ | | Width at Q50 (m) | 7.00 | 139.00 | | ||
+ | | Depth at Q50 (m) | 0.25 | 2.25 | | ||
+ | | Substrate D50 (m) | 0.01 | 0.33 | | ||
+ | |||
+ | ==== Stathab ==== | ||
+ | |||
+ | Stathab was calibrated in the same rivers as Estimhab. | ||
+ | |||
+ | ==== Stathab_steep ==== | ||
+ | |||
+ | Stathab_steep was calibrated in alpine and tropical rivers with the following characteristics: | ||
+ | |||
+ | ^ Reach characteristics ^ Minimum ^ Maximum ^ | ||
+ | | Slope(%) | 1 | 24 | | ||
+ | | Substrate, average Dm (m) | 0.001 | 0.40 | | ||
+ | | Substrate, percentile D84 (m) | 0.276 | 2.56 | | ||
+ | | Wetted width (m) | 1.24 | 19.5 | | ||
+ | | Mean annual discharge (m3/s) | 0.047 | 2.27 | | ||
+ | |||
+ | ==== FSTress ==== | ||
+ | |||
+ | Le modèle FSTress a été calibré dans des cours d’eau petits à moyens, à granulométrie faible, dont les caractéristiques sont les suivantes : | ||
+ | |||
+ | ^ Caractéristique du cours d’eau ^ Minimum ^ Maximum ^ | ||
+ | | Pente (%) | 0.07 | 3.4 | | ||
+ | | Granulométrie, | ||
+ | | Largeur mouillée (m) | 1 | 30 | | ||
+ | | Module (m3/s) | 0.003 | 12 | | ||
