Abstract: Wetlands depend on a dynamic hydrologic regime to support ecological function. Changes in catchment hydrologic behavior associated with urbanization affect the hydrologic regime of wetlands and impact their ability to perform ecosystem functions. Hydrologic analysis is important to demonstrate that development will not have negative impacts on wetlands. The research demonstrates the merit of thoughtful water balance analysis, hydrologic modelling, and the value of comprehensive data sets to support these efforts. Conceptual understanding of the study wetlands’ hydrology was refined through quantification of wetland water balances. This supported development of hydrologic models which were calibrated to known wetland hydroperiods. Continuous simulation predicted the impacts of development on the timing and nature of the wetland exchanges. Alternative green infrastructure systems were simulated and results provide evidence of the effectiveness of various systems to achieve identified hydroperiod targets which mitigate impacts of urbanization on the wetland.
