“The community of Water Balance Model users had been asking for a technical manual that documents the intelligent WBM interface that translates user information into data used by the QUALHYMO engine. The lens for manual development was the engineering user who wants to follow the numbers from the WBM interface keystroke to the QUALHYMO file. In a nutshell, it is all about data mapping,” stated Richard Boase.

“The scope of work involves extending the QUALHYMO engine and WBM interface so as to enable assessment of natural stream sections and development of an erosion index for watershed scenario comparison and development of mitigation methodologies,” explained Laura Maclean. Erosion is a key factor in water resources management. A principal result of increased volumes and rates of flow associated with urbanization is the consequent increase in stream erosion
“The addition of the Water Re-Use from Storage Module will increase the versatility of the Water Balance Model as a key tool in the City of Calgary’s toolbox of Low Impact Development strategies,” states Liliana Bozic. “Primary goals of the City’s Stormwater Strategy encompass developing cost-effective and sustainable rainwater/stormwater solutions that will work with our climate and soils. Rainwater harvesting is an area of interest that we have been working on for a number of years.”

“An increasing building footprint on properties is short-circuiting the WATER BALANCE. This creates risks for local government, both financial and environmental. If we want to make change, then we have to find a way to influence landowners to look at their properties differently,” stated Richard Boase. ““Stream health depends on ALL properties in a watershed. If everyone reduces their ‘water footprint’, and if we ensure the integrity of groundwater flow, we can then protect stream health.”
“By applying the Drainage Infrastructure Screening Tool, it is now quite easy for local governments to check and verify the relative impact of a changing climate on conveyance capacity. The resilience of a system depends on the capacity a system has now and how drastic future climate change might be. The tool also makes it is easy to assess the relative significance of changes in land use, in particular densification,” stated Jim Dumont.
