© 2019 Crown copyright. Hydrological Processes © 2019 John Wiley & Sons, Ltd. Climate change is altering river temperature regimes, modifying the dynamics of temperature-sensitive fishes. The ability to map river temperature is therefore important... Read More about Assessing the potential of drone-based thermal infrared imagery for quantifying river temperature heterogeneity.

Impact of future climate change on water temperature and thermal habitat for keystone fishes in the Lower Saint John River, Canada (2018)
Journal Article

Water temperature is a key determinant of biological processes in rivers. Temperature in northern latitude rivers is expected to increase under climate change, with potentially adverse consequences for cold water-adapted species. In Canada, little is...

Thermal infrared imaging for the detection of relatively warm lacustrine groundwater discharge at the surface of freshwater bodies (2018)
Journal Article

Thermal infrared (TIR) imaging has been previously applied to survey relatively large thermal footprints in coastal zones, lakes, reservoirs and rivers. In freshwater systems, the buoyancy of relatively warm groundwater during the winter months allow...

Avian sensor packages for meteorological measurements (2018)
Journal Article

The increasing miniaturization of accurate, reliable meteorological sensors and logging systems allows the deployment of sensor packages on lightweight airborne platforms. Here, we demonstrate the safe and humane use of avian species (white-tailed an... Read More about Avian sensor packages for meteorological measurements.

Understanding summertime thermal refuge use by adult Atlantic salmon using remote sensing, river temperature monitoring, and acoustic telemetry (2018)
Journal Article

Adult Atlantic salmon (Salmo salar) return to natal rivers several months before spawning and during summer can be subjected to temperatures that exceed their upper temperature tolerance limits. Salmon use thermal refuges to minimize exposure to high...

Effect of discharge and habitat type on the occurrence and severity of Didymosphenia geminata mats in the Restigouche River, eastern Canada (2018)
Journal Article

Copyright © 2018 John Wiley & Sons, Ltd. Since 2006, the Restigouche River watershed, eastern Canada, has been affected by nuisance growths of the mat-forming diatom, Didymosphenia geminata. In 2010, in view of the potential impacts of this alga on...

Improving representation of riparian vegetation shading in a regional stream temperature model using LiDAR data (2017)
Journal Article

Modelling river temperature at the catchment scale is needed to understand how aquatic communities may adapt to current and projected climate change. In small and medium rivers, riparian vegetation can greatly reduce maximum water temperature by prov...

River temperature modelling: a review of process-based approaches and future directions (2017)
Journal Article

Low flow controls on stream thermal dynamics (2017)
Journal Article

Stream temperature under contrasting riparian forest cover: Understanding thermal dynamics and heat exchange processes (2017)
Journal Article

Climate change is likely to increase summer temperatures in many river environments, raising concerns that this will reduce their thermal suitability for a range of freshwater fish species. As a result, river managers have pursued riparian tree plant...

Automating drainage direction and physiographic inputs to the CEQUEAU hydrological model: Sensitivity testing on the lower Saint John River watershed, Canada (2017)
Journal Article

© IWA Publishing 2017. CEQUEAU is a process-based hydrological model capable of simulating river flows and temperatures. Despite an active user base, no facility yet exists for the automatic assembly and input of watershed data required for flow simu...

Controls on Arctic glacier-fed river water temperature (2016)
Journal Article

The impact of climate change on Arctic rivers is expected to be severe. There is therefore a need for greater understanding of Arctic river temperature processes. This study quantifies the spatio-temporal variability of water temperatures in the Kårs... Read More about Controls on Arctic glacier-fed river water temperature.

A practitioner's guide to thermal infrared remote sensing of rivers and streams: recent advances, precautions and considerations (2016)
Journal Article

Stream temperature is a key habitat variable controlling all physical and biological river processes. In light of the threat of climate change to fluvial environments, growing importance is being placed on the need to gain a better understanding of s...

Journal Article

Temporal variability of thermal refuges and water temperature patterns in an Atlantic salmon river (2013)
Journal Article

In response to high summer river temperatures, salmonids avoid heat stress by making use of discrete units of cold water termed thermal refuges. Although recent research has documented how their spatial arrangement within a river affects salmonid dis...
