Guide for Actively Managing Watershed-Scale Numerical Models in Ontario
document was prepared using funding provided by the Province of Ontario through
the Source Water Protection Program.
The report was
prepared by staff from the Oak Ridges Moraine Groundwater Management Program
(ORMGP) and was supported by staff from the Ministry of Natural Resources and Forestry and
the Ministry of the Environment and Climate Change, as well as from the
Credit/Toronto/Central Lake Ontario (CTC) and the Lake Erie Source Water
Protection Programs (SWP). A peer review committee was also established
to provide additional guidance and support through the development of the
are effective tools to assist with decision-making in water
allocation, protection of water sources, and for risk-reduction policies for
extreme conditions (e.g., flood and drought). Acting on this, recognition,
preparation, and use of numerical models is now routinely required for various
water resources management initiatives across the province.
The work inherent
in watershed-scale numerical modelling, specifically the need for the assembly,
review and analysis of large collections of data, results in a tremendous synthesis
of water resources information across Ontario's watersheds. This numerical
model driven synthesis of water related information is now recognized as an
effective and ongoing watershed management tool for Ontario.
It is intended
that this guide will raise awareness of the need to reposition Ontario’s water
managers to integrate numerical modelling as a standard water management tool for
developing policies, infilling data gaps, impact assessment, scenario analyses,
communicating the behaviour of complex environmental systems to stakeholders,
and decision making with regards to a wide range of water resources concerns.
It is also intended to equip water managers with the ‘know how’ to effectively
manage the numerical modelling pathway so that Ontario may capitalise on the
full potential of numerical modelling.
