| Summary: | Urban and rural watersheds are becoming increasingly vulnerable to extreme weather events and their consequences. One such consequence is flooding. Stormwater management systems need to be efficiently designed to handle both the quantity and quality of floodwaters. Efficient stormwater systems can be achieved when design parameters are set to their optimum. The design parameters for proper sizing of stormwater infrastructure are obtained from design storms, a combination of Intensity-Duration-Frequency (IDF) curves and a rainfall temporal distribution. IDF curves are developed using rainfall data; as such, changes to the climate will affect these curves. There is a need to re-evaluate the current design storms to determine how they will be affected by the changing climate. Evaluating a design storm from a chaotic variable such as precipitation is complex, and the variation in climate makes it more complicated. Information on IDF curves is challenging to obtain, especially at locations where precipitation ... |
