Water temperature modelling in a small forested stream: implication of forest canopy and soil temperature

Predicting water temperatures using a deterministic model: Application on Miramichi River catchments (New Brunswick, Canada)

“…Marcotte and Duong, 1973, SF = 0.05-0.40;Sinokrot and Stefan, 1993, SF = 0.0-0.70;St-Hilaire et al, 2000, SF = 0.6). It should be noted that the study by St-Hilaire et al (2000) was also conducted at Catamaran Brook, using the CEQUEAU model and that the SF of the present study was very close to this previous study. The higher SF value at the Little Southwest Miramichi River reflects that this river is more exposed to climatic conditions at 80 m wide, whereas Catamaran Brook is more sheltered by riparian vegetation.…”

Riparian Forest Harvesting Effects on Maximum Water Temperatures in Wetland-sourced Headwater Streams from the Nicola River Watershed, British Columbia, Canada

“…We did not observe any statistically significant temporal shift in the T max,7-day avg date in the two watershed under study following riparian harvesting along NTC during 2000, but our sample size was small and a larger study could make more definitive conclusions. It is of note that other work has reported groundwater-driven increases in stream temperature due to riparian harvesting (Curry et al 2002), consistent with the increased heat flux into groundwater in cut blocks (St-Hilaire et al 2000). To the best of our knowledge, only one previous study (Mellina et al 2002) has specifically considered the effects of riparian harvesting on downstream temperature patterns in headwater streams from wetlands and other small lentic systems.…”

Response of western Oregon (USA) stream temperatures to contemporary forest management

“…Solar exposure of clear-cut soils may affect evapotranspiration and soil temperatures (Kim and Ek, 1995). St-Hilaire et al (2000) improved empirical stream temperature model fits by including the effect of solar exposure on soil temperatures. Hewlett and Fortson (1982) found that despite the presence of a 10-15 m wide riparian buffer along their study site in Georgia, USA, their study stream temperatures increased by more than 11°C, much more than the authors estimated would occur under conditions of complete riparian zone removal.…”
