Computerized Tool for the Development of Intensity-Duration-Frequency Curves under Climate Change – Version 3.0

This computerized web-based IDF tool integrates a user interface with a Geographic Information System (GIS). By creating or selecting a station (Gauged IDF) or selecting a location on the map (Ungauged IDF) the user will be able to carry out statistical analysis on historical data, as well as generate and verify possible future change based on a methodology using a combination of climate modeling outputs and locally observed weather data.
