FLASHBACK TO 2002: Metro Vancouver hosted inaugural Partners Forum that initiated development of the web-based "Water Balance Model for British Columbia" (July 2002)


The ‘date of record’ for formal launch of the Inter-Governmental Partnership (IGP) to ‘make real’ the vision for the WBM initiative is July 17, 2002. On that date the Greater Vancouver Regional District (now known as Metro Vancouver) convened a meeting of representatives from three levels of government. “The defining outcome of that inaugural Water Balance Partners Forum was the decision to fund and proceed with WBM development,” stated Kim Stephens.

FLASHBACK TO 2002: Early decision-making by the Inter-Governmental Partnership was guided by a Backgrounder titled "The Water Balance Model: A Tool for Stormwater Source Control Modeling in a Watershed Context" (July 2002)


“The WBM can be applied to evaluate the hydrologic performance of stormwater source
controls (e.g. bioretention, infiltration facilities, rainwater capture and re-use, green roofs)
and stormwater detention,” stated Dr. Dan Medina. “The output hydrograph generated by the WBM can become an input to a wide range of hydraulic routing models. WBM hydrographs represent a major improvement over conventional hydrologic simulation of urban runoff.”
