Hyfran Plus -

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.

Let's address the elephant in the room:

The software goes beyond simple fitting by automatically performing critical statistical tests to validate your data:

Selecting the correct probability distribution is arguably the most challenging part of frequency analysis. The built-in DSS provides rigorous step-by-step algorithms—utilizing the Jarque-Bera test, log-log plots, and Mean Excess Functions (MEF)—to objectively guide users toward the mathematical class that best fits their sample.

While several manufacturers produce "Hyfran" type products, the "Plus" variant is universally recognized as the spec for high-stress environments where failure is not an option.

The "Plus" version allowed engineers to account for trends over time, such as increasing rainfall due to global warming. Decision Support: 📩 DM us or visit [Link]

: Researchers use it to develop Intensity-Duration-Frequency (IDF) curves and estimate rainfall depths for specific return periods (e.g., a 1-in-100-year event). Availability and Documentation

This integration ensures that the hydraulic models are based on robust statistical probability, resulting in more accurate flood zone mapping. Why Choose Hyfran Plus?

Imagine a small town built near a river that has experienced "minor" flooding every few years. The town's engineers want to build a new bridge, but they need to know how high to make it so it doesn't get swept away by a "once-in-a-hundred-years" flood. a 1-in-100-year event).

Manufacturers are currently developing "Hyfran Plus Gen 2," which is rumored to integrate aerogel particles. This would drop the lambda value down to 0.020 W/m·K while maintaining the same mechanical strength. Additionally, "Smart" Hyfran Plus with embedded RFID chips is being tested for district heating utilities, allowing maintenance robots to read the insulation's health without removing cladding.

Ensures accurate risk assessment for hydraulic structures.

The software takes raw historical datasets (often spanning 30–50 years) and summarizes them to identify peaks and patterns.

The software includes 18 statistical distributions categorized by their "tail" behavior:

The true value of HYFRAN-PLUS is demonstrated in its wide range of real-world applications. Here are three examples:
