British Columbia’s Partnership for Water Sustainability and the United States Urban Watersheds Research Institute have an agreement to collaborate: "The Water Balance Model’s QUALHYMO engine is now linkable with SWMM," stated Jim Dumont, the Partnership’s Engineering Applications Authority

Note to Reader:

The Partnership for Water Sustainability in British Columbia (“the Partnership”) delivers services on behalf of government. In particular, the Partnership is responsible for the Water Sustainability Action Plan for British Columbia. Under this umbrella, the Partnership is leading the Georgia Basin Inter-Regional Educational Initiative (IREI).

The Partnership develops online tools and delivers capacity-building programs on behalf of government. These programs provide professional development and tackle “the disconnect” between information and implementation in the local government setting.

Given the evident benefits of strategic interaction, the Partnership and the Urban Watershed Research Institute (UWRI) have an agreement to collaborate regarding reciprocal benefits and joint actions related to water resources research and practice in North America.

Synergies in Action

“The Partnership for the Water Sustainability is excited to enter into an agreement with the Urban Watershed Research Institute (UWRI) to collaborate in the advancement of water resources research and practice in North America. The focal point for this collaboration is found at,” stated Ted van der Gulik, President.

Formerly the Senior Engineer in the Province of British Columbia’s Ministry of Agriculture, Ted van der Gulik received the 2014 Legacy Award when he retired from government. He was also an inaugural inductee into the British Columbia Public Service Hall of Excellence.

“This is a mutually beneficial strategic partnership founded on strong human links,” continued Ted van der Gulik.  “Since 2005, Dr. Charles Rowney has been the Partnership’s Scientific Authority. And, as the Director of Operations for the new Center for Infrastructure Modeling and Management, Charles is a driving force behind

“In addition, Jim Dumont, our Engineering Applications Authority, now sits on the Center’s panel of expert advisors. This provides a wonderful opportunity for Jim Dumont to cross-fertilize his experience with that of his peers in the United States and elsewhere.”

to sharing and learning

“Under an agreement with the US Environmental Protection Agency, has been created to provide sustainable research, development and outreach for water CharlesRowney_2016_120pinfrastructure modeling, initially focusing on two foremost modelling tools – known around the world by the acronyms EPA SWMM and EPANET,” stated Dr. Charles Rowney, the Center’s Director of Operations.

“We will certainly tap into the British Columbia Partnership’s Water Balance Model experience as the Center explores options for SWMM and EPANET deployment beyond the desktop.



British Columbia’s Whole-System,
Water Balance Approach

“The British Columbia Partnership’s understanding of hydrology and watershed management issues in the Pacific Northwest provides some intriguing insights into new diagnostics, targets and interpretation needs for watersheds, and the tools we develop will very likely need to embrace those ideas,” continued Dr. Rowney.

“The Water Balance Model’s QUALHYMO calculation engine is now linkable with SWMM. This would fill a need in watershed assessment and enable setting of performance targets for a whole-system, water balance approach to restoring and protecting watershed health.”

Water Balance Methodology

“Watershed protection starts with an understanding of how water gets to a stream, and how long it takes,” continued Jim Dumont. “Protection of watershed and stream health in the urban environment ultimately depends on maintaining the natural proportion of rainwater entering streams via three pathways: overland runoff, shallow interflow and deep groundwater flow.

Mimic-Water-Balance_Feb-2014“The innovation of the Water Balance Methodology is in the way it integrates and applies standard scientific and engineering principles to address these components in ways which are not typically applied in planning and design of municipal infrastructure.

“Tools like SWMM and QUALHYMO can enable the hydrologic computations; it is up to us to recognize the need, and to deliver tools that facilitate the analysis.  I expect that discussions about methodology will be as much a part of the new Center as the development of new code,” concluded Jim Dumont.

Primer on Water Balance Methodology_Feb-2014_cover_500pThe “Beyond the Guidebook Primer Series” supports implementation of targets and actions listed in Living Water Smart: British Columbia’s Water Plan. The targets and actions establish expectations as to how land will be (re)developed so that stream and watershed health are protected and/or restored.

The Primer on Water Balance Methodology for Protecting Watershed Health is the fifth in a series of guidance documents that form the basis for knowledge-transfer via the Georgia Basin Inter-Regional Education Initiative (IREI). The foundation document for the series is Stormwater Planning: A Guidebook for British Columbia, released in 2002.

The goal in producing the “Beyond the Guidebook Primer Series” is to facilitate inter-regional collaboration, such that sharing and cross-fertilization of experience and understanding helps all local governments go farther, more efficiently and effectively.
