CRC-FORGE application

This application provides catchment and point estimates of design rainfall at preset durations and annual probabilities (in the form of a table) for design or checking of flood capacity of medium to large civil engineering infrastructure. It provides rainfall estimates out to rare annual probabilities (defined here as being less than 1 in 1,000).

This application accepts catchment or point definition (in the form of imported text files) or by clicking on an imported map. Input is displayed on a basic location map of Queensland, and can be edited as necessary.

Usage and utility

This application is widely used by civil engineering professionals dealing with infrastructure in Queensland — e.g. spillway capacity and robustness of dams, general flood estimates for urban areas, and levees including on mine sites.

It is often used in conjunction with Australian Rainfall and Runoff (AR&R) — a guide text for hydrology. While AR&R is currently being reviewed, the rainfall estimates even from the new AR&R are unlikely to cover rare annual probabilities.

Installation instructions

  1. Download CRC-FORGE (ZIP, 181 MB) 
  2. Open and copy all the files into a directory of your choice
  3. Double-click the executable (.exe) file. Consider creating a shortcut for regular use.
  4. There is help within the application and a basic guide manual. Older PCs should not take more than a minute to run the application.

For those who already have the data set and files, but may have encountered difficulty with the application on Windows 7, the revised executable can be downloaded individually (EXE, 681.5KB).

System requirements

This application runs on the Windows operating system using .NET to access the graphical user interface. The revised application requires at least version 3.5 of the .NET framework. In most cases this version of .NET will already be installed with Windows.

Any issues with the application should be directed to:
