Parameter sensitivity of a surface water quality model of the lower South Saskatchewan River—Comparison between ice-on and ice-off periods (2016)
Journal Article

Little is known about seasonal differences (ice-on vs. ice-off periods) and the sensitivity of in-stream processes to surface water quality constituents in rivers that have a persistent ice cover in winter. The goal of this study is to investigate th...

Assessing the relative importance of parameter and forcing uncertainty and their interactions in conceptual hydrological model simulations (2016)
Journal Article

Predictions of river flow dynamics provide vital information for many aspects of water management including water resource planning, climate adaptation, and flood and drought assessments. Many of the subjective choices that modellers make including m...

Forms and drivers of annual streamflow variability in the headwaters of Canadian Prairies during the 20th century (2016)
Journal Article

Headwater streamflows in the Rocky Mountain foothills are the key to water availability in the Canadian Prairies. Headwater characteristics, however, have been and continue to be subject to major variability and change. Here, we identify various form...

The effect of fallow period length on the abundance and diversity of usable plant assemblages in shifting cultivation system (Swidden agriculture) in northern Laos (2016)
Journal Article

Shifting cultivation, or swiddening, involves alternating cycles of cropping and fallow periods. Rather than being abandoned, the fallow swidden fields provide a source of important plant products for remote, forest-dwelling human communities. In nor...

Recent climatic, cryospheric, and hydrological changes over the interior of western Canada: A review and synthesis (2016)
Journal Article

It is well established that the Earth's climate system has warmed significantly over the past several decades, and in association there have been widespread changes in various other Earth system components. This has been especially prevalent in the c... Read More about Recent climatic, cryospheric, and hydrological changes over the interior of western Canada: A review and synthesis.

Quantifying spatial changes in the structure of water quality constituents in a large prairie river within two frameworks of a water quality model (2016)
Journal Article

A global sensitivity analysis was carried out on a water quality model to quantify the spatial changes in parameter sensitivity of a model of a large prairie river, the South Saskatchewan River (SSR). The method is used to assess the relative impacts...

Insights into plant water uptake from xylem-water isotope measurements in two tropical catchments with contrasting moisture conditions (2016)
Journal Article

Water transpired by trees has long been assumed to be sourced from the same subsurface water stocks that contribute to groundwater recharge and streamflow. However, recent investigations using dual water stable isotopes have shown an apparent ecohydr...
