Ice jam flood hazard assessment and mapping of the Peace River at the Town of Peace River (2015)
Presentation / Conference Contribution

Efforts are underway in Canada to develop, update and extend flood risk assessments and mapping for river sections prone to flooding. However, most of these previous works are limited to the open-water case. Very little has been done to include flood...

Dynamic water quality modelling and uncertainty analysis of phytoplankton and nutrient cycles for the upper South Saskatchewan River (2015)
Journal Article

The surface water quality of the upper South Saskatchewan River was modelled using Water Quality Analysis Simulation Program (WASP) 7.52. Model calibration and validation were based on samples taken from four long-term water quality stations during t...

Who smells? Forecasting taste and odor in a drinking water reservoir (2015)
Journal Article

Taste and odor problems can impede public trust in drinking water and impose major costs on water utilities. The ability to forecast taste and odor events in source waters, in advance, is shown for the first time in this paper. This could allow water... Read More about Who smells? Forecasting taste and odor in a drinking water reservoir.

Tree rings provide early warning signals of jack pine mortality across a moisture gradient in the southern boreal forest (2015)
Journal Article

Recent declines in productivity and tree survival have been widely observed in boreal forests. We used early warning signals (EWS) in tree ring data to anticipate premature mortality in jack pine (Pinus banksiana) - an extensive and dominant species...

An efficient calibration technique for heat dissipation matric water potential sensors (2015)
Journal Article

Heat dissipation sensors are used to measure matric potential in soils. A van Genuchten equation can be used to fit the relationship between measured heat dissipation and matric potential. Calibration is required for each probe because of intrinsic v... Read More about An efficient calibration technique for heat dissipation matric water potential sensors.

Unpacking viewpoints on water security: Lessons from the South Saskatchewan River Basin (2015)
Journal Article

Water is essential for human development and the environment; however, its security is challenged by factors such as competing uses, over extraction, and divergent perspectives. The focus of this paper is to better understand how different stakeholde... Read More about Unpacking viewpoints on water security: Lessons from the South Saskatchewan River Basin.

Temporal dynamics of catchment transit times from stable isotope data (2015)
Journal Article

Time variant catchment transit time distributions are fundamental descriptors of catchment function but yet not fully understood, characterized, and modeled. Here we present a new approach for use with standard runoff and tracer data sets that is bas... Read More about Temporal dynamics of catchment transit times from stable isotope data.

Beaver-mediated methane emission: The effects of population growth in Eurasia and the Americas (2015)
Journal Article

Globally, greenhouse gas budgets are dominated by natural sources, and aquatic ecosystems are a prominent source of methane (CH4) to the atmosphere. Beaver (Castor canadensis and Castor fiber) populations have experienced human-driven change, and CH4...

North American precipitation isotope (δ18O) zones revealed in time series modeling across Canada and northern United States (2015)
Journal Article

Delineating spatial patterns of precipitation isotopes ("isoscapes") is becoming increasingly important to understand the processes governing the modern water isotope cycle and their application to migration forensics, climate proxy interpretation, a... Read More about North American precipitation isotope (δ18O) zones revealed in time series modeling across Canada and northern United States.

Divergent Perspectives on Water Security: Bridging the Policy Debate (2015)
Journal Article

Environmental policy discussion is replete with references to water security, food security, ecosystem health, community resilience, sustainable development, and sustainable urbanism. These terms are, by their very nature, ambiguous and difficult to... Read More about Divergent Perspectives on Water Security: Bridging the Policy Debate.
