: The software includes 18 different probability distributions (such as Gumbel, GEV, Log-Pearson Type III, and Weibull) to fit data samples that are independent and stationary.

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

HYFRAN-PLUS operates primarily on the assumption that the uploaded dataset consists of random, independent, and identically distributed (IID) variables. When evaluating environmental anomalies over several decades, users run independent tests to ensure data validity before finalizing infrastructure dimensions.

The "Plus" version allowed engineers to account for trends over time, such as increasing rainfall due to global warming. Decision Support:

Ensures accurate risk assessment for hydraulic structures.

The story began with a fundamental problem in civil engineering: how do you build a bridge or a dam if you don't know how big the "100-year flood" will be? Engineers needed a way to fit statistical distributions to historical water-flow data to estimate the probability of rare, catastrophic events. The Development of Hyfran Initially, the software was known simply as
