Statistical Modeling to Study Climate Change Impacts on Municipal Stormwater Intensities

Lynker conducted modeling using the R statistical language to evaluate the effect of climate change on the Intensity-Duration-Frequency (IDF) curves used by Prince Edward Island to assess their municipal stormwater system.  Lynker obtained data and correlated specific climate variables with recorded storm intensities.  Once the ideal variables were selected, future projections of these variables from the Global Climate Models were used to predict the future distribution of the intensity and return interval of storm events.  These distributions were then used to evaluate the deviation from the IDF curves currently used by the municipality.
