Hyfran Plus Hot! -

is a highly specialized, world-class statistical software application designed to fit mathematical probability distributions to extreme environmental data. Originally developed by the Chair in Statistical Hydrology at the National Institute of Scientific Research (INRS-ETE) in Canada, it has become the global industry standard for engineers, meteorologists, and environmental scientists who need to predict the severity and frequency of extreme natural phenomena.

Developed by the Chair in Statistical Hydrology at the in Quebec, Canada, it is the advanced successor to the original HYFRAN software. While the original HYFRAN is no longer available, HYFRAN-PLUS includes all of its tools and more, making it the definitive version from the research team.

A 2025 study in the Lower Filyos Basin combined HYFRAN-PLUS with HEC-RAS and HEC-HMS hydrological modeling software. The research analyzed flood dynamics for return periods of 2, 5, 10, 20, 50, and 100 years. The analysis revealed that while precipitation volume increased, the amount of water converted to surface runoff remained limited due to infiltration and other losses—a critical finding for basin management and flood prevention strategies. hyfran plus

is more than just insulation; it is a structural asset. It solves the eternal engineering conflict between "strength" and "insulation." For projects that involve water, weight, extreme temperatures, or long-term operational costs, downgrading to a cheaper material is a false economy.

The study went further to produce synthetic storms using the Soil Conservation Service (SCS) technique type II, distributing rainfall depth for return periods of 5, 10, 25, 50, and 100 years. These synthetic storms were used to generate complete IDF curves for the semi-arid region. While the original HYFRAN is no longer available,

: Engineers gather decades of historical river flow data and plug it into HYFRAN-PLUS.

In a 2026 study, researchers used HYFRAN-PLUS to estimate the 100-year return period for rainfall events in arid coastal basins of Egypt’s Northwest Coast. This analysis was crucial for hydrological modeling that identified basins with the highest peak discharge and flood inundation depths, providing vital data for flood risk management and land-use planning.
