Stormwater management (SWM) ponds are among the most common approaches to stormwater management in Ontario, often as part of a treatment train.
Vegetation is a key but often overlooked component of SWM ponds; there is little information regarding targeting vegetation plantings to optimize treatment functions.
We have undertaken a comprehensive survey of stormwater management pond vegetation and its relation to hydraulics and water quality to better inform stormwater management pond design and optimize its functionality.
Our sites in southern Ontario have been selected based on the availability of design specifications and monitoring of water quality and hydraulics. Vegetation characteristics (species richness, diversity, evenness, percent cover, density) are being quantified and water quality samples obtained from the inlet and outlet. Water samples are being tested for BOD, COD, TSS, and pH.
