Assessment and prediction of “water quality” is key to sustainable watershed management. The Watershed Science and Modelling Laboratory seeks researches to understand processes associated with nutrient cycling and other water pollutants, their fate and transport throughout the watersheds. The focus is an integrated assessment of processes involved in hydrology, surface/ground water interactions, and water pollutants. The outcome is to develop Decision Support System which is capable of assessing water resources holistically. The lab provides an ideal environment to support researches of this kind in the future, and it promotes collaboration with other researchers who have similar interests on detecting and assessing the pollutants’ concentration (e.g., metals, nutrients, pesticides, bacteria, etc.), and their fate and transport throughout the watersheds. The WSML is currently seeking grants to support integrative water quality research projects.
