Biography Summary

William (Bill) K. Annable is an Associate Professor in the Department of Civil and Environmental Engineering at the University of Waterloo. He is affiliated with Professional Engineers of Ontario, the Association of Professional Geoscientist of Ontario, the American Geophysical Union, the Geological Society of America, and the International Association of Hydrogeologists.

He has been researching the hydraulic, sediment transport and morphological characteristics of rivers for over the past 18 years. In addition, he has been designing, monitoring and supervising the construction of natural channel restoration projects throughout North America - totalling over 2,500km of streams and rivers studied and over 180km of restored river channels.

Professor Annable’s recent research has focused on the sediment transport characteristics of urban river systems and how changes in hydrology affect habitat dynamics. He is specifically interested in river restoration, rehabilitation and aquatic habitat improvements. The study of basin scale isotope hydrology and sediment transport of non-point source contaminants, along with conducting numerical and field studies of groundwater surface water interaction and karst hydrology are other interests of his as well. Additionally, Professor Annable conducts field and numerical modelling studies on urban river mechanics, hydraulics and hydrology.

His current sources of research funding are from NSERC, CFI, EPA, Water Districts, Municipalities, and DFO.
