Modelling Objectives for WATFLOOD®
WATFLOOD is the first hydrological model to compare isotope flow separation measurements to computed flows from source areas in a watershed. This feature is of the utmost importance for water quality modelling by ensuring that contributions to streamflow are properly assigned to their sources.
About the developers:
Dr. Nick Kouwen is a Distinguished Professor Emeritus and Adjunct Professor at the University of Waterloo, a registered Professional Engineer in Ontario and a Fellow of the American Society of Civil Engineers.
He currently provides support to the WATFLOOD user community which currently includes Manitoba Hydro, Ontario Ministry of Natural Resources, Lake of the Woods Control Board, Manitoba Ministry of Infrastructure and Technology, 4DM Consulting (Toronto), Conestoga Rovers (Waterloo), NRC and the University of Manitoba.
Dr. Kouwen acknowledges the work of Ric Soulis, Todd Neff, Frank Seglenieks, Luis Leon, John Donald, Wayne Jenkinson and Trish Stadnyk who have contributed substantially to to the development of WATFLOOD.
Dr. Kouwen is known for the development of the WATFLOOD hydrological model and for the development of flow resistance relationships for vegetation in channels and on flood plains. WATFLOOD was the first non-urban hydrological model to use the Grouped Response Unit (GRU). Dr. Kouwen’s unique experience in dealing with vegetated channels and other hydraulic problems, as well as several years working on highway construction projects, conducting hydrological field work and life on a farm, has resulted in a hydrological model that robustly represents the hydrological processes of watersheds from a few km2 to watersheds as large as the Great Lakes and the Mackenzie River. firstname.lastname@example.org

Dr. Trish Stadnykis an Associate Professor with the Department of Civil Engineering at the University of Manitoba, and a registered Professional Engineer with the Engineers and Geoscientists Manitoba. She is also a National Director and Manitoba Board member for the Canadian water Resources Association, Chair of the Manitoba Chapter of the Canadian Society for Civil Engineering and Chair of the Canadian Geophysical Union’s Isotope Tracer Committee. She is a specialist in hydrologic modelling and the use of stable water isotope tracers to segregate runoff flow paths.
Dr. Stadnyk has been a developer and user of WATFLOOD for nearly 20 years, starting as a researcher for Dr. Kouwen with major contributions to code efficiency, wetland hydrology and routing, hydrograph separation modules, and most recently, isotope tracers (isoWATFLOOD). Her research aspires to help fill the gap in our understanding of large river basins and mesoscale hydrological processes by providing tools to assist researchers, governments and regulatory bodies in evaluating mesoscale hydrologic processes for such river basins. Her research development focus is on identifying and validating flow paths and sources within mesoscale hydrologic models by applying stable water isotope tracers. Dr. Stadnyk also has considerable experience applying WATFLOOD for long-term water supply studies under climatic change and for short-term forecasting studies, with particular focus on large Canadian river basins and arctic-freshwater linkages. She collaborates directly with industry and government in regards to using and setting up the WATFLOOD model for various applications, and offers training workshops to assist potential new users. email@example.com
Key words: WATFLOOD; CHARM (Canadian Hydrological And Routing Model); Grouped Response Units GRU's; Hydrologically Similar Units HSU's; Aggregated Simulation Areas ASA's; Hydrotops; Pixel Grouping; Tiles. These are some of the names used by other modellers for the GRU method. The GRU method originates (!!!!) with WATFLOOD - first published by Tao & Kouwen in 1989.
