Computerized Tool for the Development of Intensity-Duration-Frequency Curves under Climate Change – Version 5.0

IDF_CC is a publically available web-based intensity-duration-frequency tool to update and adapt local extreme rainfall statistics to climate change. The IDF_CC tool is pre-loaded with 898 Environment and Climate Change Canada rain stations. Users can select any rain station with 10 or more years of data and develop IDF curves based on historical data and curves adjusted to reflect climate change. The tool also allows the development of IDF curves for ungauged locations in Canada. The User and Technical Manuals (available for download from the Help menu)provide details on how to use the tool and the methodology used to develop the tool.
