Water Balance Model

How to Use the Model

The substantial benefits to the user in applying the “Water Balance Model powered by QUALHYMO” are three-fold: first, source control types are pre-defined; secondly, there is the ability to quickly create the QUALHYMO input files; and thirdly, the standardized output allows easy and quick review by regulatory agencies.

About the Model

The web-based “Water Balance Model powered by QUALHYMO” integrates the site with the watershed, stream and groundwater aquifer. This scenario comparison tool underpins Beyond the Guidebook, a provincial initiative to advance implementation of green infrastructure policies and practices throughout British Columbia.
