Estran automates the analytical heavy lifting of flood risk assessment — vulnerability mapping, multicriteria scoring, adaptation scenario comparison — so municipalities and engineering firms can move from raw data to defensible recommendations without commissioning a full hydrological study for every scenario. The vendor states that agentic AI handles a substantial portion of the hydrological analysis, with human judgment retained for the roughly 20% of decisions that require discretionary calls. That division matters: the platform is not a replacement for a licensed engineer, it's a capacity multiplier. Where it breaks is at the edges of the regulatory model — teams working on cross-provincial projects or operating outside Quebec's 2026 framework will find the tool's specificity becomes a constraint rather than an advantage.
