HYFRAN-PLUS is a commercial software product with a clear and transparent pricing structure:

A comprehensive study published in the Iraqi Geological Journal demonstrated the power of HYFRAN-PLUS for rainfall frequency analysis. Researchers tested eleven theoretical probability distributions to simulate observed rainfall probability. Using the Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC), the study objectively identified the in the research region. hyfran plus

(Hydrological Frequency Analysis Plus Decision Support System) is a premier statistical analysis software engineered to fit mathematical probability distributions to datasets of extreme environmental events. Originally developed by Dr. Bernard Bobée and his research team at the Institut National de la Recherche Scientifique (INRS-ETE) in Quebec, Canada, this tool serves as an industry standard for civil engineers, meteorologists, and environmental scientists. It transforms raw environmental time series into actionable risk metrics.

Innovation meets efficacy with Hyfran Plus . It transforms raw environmental time series into actionable

HYFRAN-PLUS is more than just software; it is a comprehensive solution for statistical frequency analysis, born from decades of academic research and refined through countless real-world applications. By integrating a powerful Decision Support System with a vast library of statistical distributions and robust validation tests, it empowers engineers, hydrologists, and scientists to move beyond simple analysis and make credible, defensible predictions about rare and impactful events. Whether planning a dam's spillway, designing urban drainage for a 100-year storm, or assessing the changing risks of a warming climate, HYFRAN-PLUS provides the analytical muscle needed to navigate uncertainty with confidence.

HYFRAN-PLUS represents a mature, research-backed solution for hydrological frequency analysis. Developed at one of the world's leading centers for statistical hydrology research, the software combines comprehensive distribution libraries, sophisticated fitting methods, and an intelligent Decision Support System to help engineers and researchers make informed decisions about extreme event analysis.

It is used to assess the state of rivers and the effectiveness of constructed dams. By calculating the cumulative moving average (CMA) of data series at gauging stations, engineers can determine the impacts of hydraulic structures over time. IDF Curve Generation
