Software and guidance documents

Download, documentation, and training resources for RMC-BestFit, free software for curve fitting and estimation with a range of probability distributions.
Download, documentation, and training resources for the Statistical Software Package (HEC-SSP). HEC-SSP combines all of the statistical analyses capabilities of HEC-FFA (Flood Frequency Analysis), STATS (Statistical Analysis of Time Series Data), REGFRQ (Regional Frequency Computation) and MLRP (Multiple Linear Regression Program).
This link includes download instructions and background for TUFLOW FLIKE,, developed by Professor George Kuczera from the University of Newcastle. FLIKE is an extreme value analysis package that calculates the probability of flood events based on historical records. Instructions for using FLIKE are included in Australian Rainfall and Runoff Book 3.
Download, documentation, and training resources for Reservoir Frequency Analysis (RMC-RFA).
