Dr. Bill Annable, PhD, PhD, PEng, PE, PGeo, is an Associate Professor of Civil and Environmental Engineering at the University of Waterloo in Ontario, Canada. Bill has been researching the hydraulic, sediment transport, morphologic and eco-hydraulic characteristics and linkages of rivers across North American and Europe for the past 25 years. His principle areas of research focus on investigating the effects of hydromodification due to land-use change on both urban and rural settings and the bio-physical linkages between aquatic communities and their physical habitat conditions (including hydraulics, sediment transport, and groundwater / surface water interaction). In addition to theoretical and applied research, Dr. Annable has also been designing, monitoring and supervising the construction of river rehabilitation projects across North America totaling over 3,000 km of rivers studied and over 200km of river channels rehabilitated. Bill has also been investigating with colleagues the eco-hydraulic linkages of domesticated watersheds in Switzerland and Italy to assist with developing rehabilitation strategies to effectively rehabilitate watercourses historically affected by hydropeaking schemes.
