Historically replacing its core predecessor, HYFRAN, the "PLUS" edition introduces an advanced Decision Support System (DSS). This intelligent engine guides professionals through the labyrinth of statistical modeling, helping them select the most appropriate mathematical equations to project return periods—such as 50-year or 100-year extreme events—with mathematical confidence. Core Analytical Capabilities and Framework
is applied in several critical areas of water resource management: Flood Frequency Assessment
is a specialized software application used primarily by hydrologists, engineers, and environmental researchers to conduct Hydrological Frequency Analysis . Developed by the research institute INRS-ETE , it provides a suite of mathematical tools to analyze extreme events—such as floods, heavy rainfall, or droughts—to predict their return periods and design values.

Hyfran Plus pays for itself the first time you don't have to repair a system. For critical infrastructure (hospitals, data centers, pharma plants), it is the only rational economic choice.
is an industry-standard specialized software designed to fit statistical distributions to extreme datasets in hydrology and environmental sciences. Developed by the Institut national de la recherche scientifique (INRS-ETE) in Canada, the software functions as a sophisticated Decision Support System (DSS). It enables hydrologists, engineers, and researchers to predict the frequency and magnitude of extreme natural events like catastrophic floods, intense rainfall, and severe droughts. It enables hydrologists
The software goes beyond simple fitting by automatically performing critical statistical tests to validate your data:
This combination eliminates the "ball bearing" effect of water trapped in flocs, releasing free water for fluidity. The result: a highly dispersed cement matrix with significantly reduced yield stress and plastic viscosity.
