Ponds and detention systems
Pond riser, Unsworth Reserve.
Constructed stormwater ponds are used in New Zealand to alleviate flooding and reduce the concentration of pollutants in water reaching downstream environments such as estuaries.
Our research has focused on better understanding the physical, chemical, and biological processes that change the hydrochemistry of water in urban stormwater ponds. The results are helping us in better pond planning, positioning and planting to achieve desirable performance. Data are being used for numerical modelling to help predict catchment behaviour.
