Problem

Is it possible to change or adjust the IDF Curve Equation or the IDF Table Equation used in the Storm Events dialog?

Solution

It is not possible to make a change the IDF curve equation or table equation, as they are hard-coded into the program.

If you have a different equation, it is recommended to use Excel to calculate the intensity values, and then use those values to create a User Defined IDF Table.

Here are two ways this can be done.

Option 1

1. Use Excel to calculate the intensity values.

2. Copy the values from Excel.

3. Paste them into the User Defined IDF Table in the Storm Data dialog.

Option 2

Excel files can be saved in a .txt or .csv format, which can be imported into the IDF table using the steps in the following link: What is the expected text file format for IDF import?
