We’re pleased to welcome Thibault Lebeke, Industrial Manager at BWI. With over 10 years of experience in spacecraft engineering and a strong background in flight dynamics and system coordination, Thibault contributes to the REVALTO mission by managing industrial partners and technical interfaces – ensuring high-quality space data to power advanced hydrological forecasting.

We’re pleased to welcome Roxane Blattes, Project Management Officer at BWI. With a PhD in Biology, an MBA, and extensive experiences in program governance, Roxane supports the REVALTO satellite mission by overseeing planning, risks and cost management – contributing to the delivery of high-revisit hydrological data for improved water monitoring.

Climate volatility makes accurate river flow forecasting mission-critical for hydropower operators, irrigation planners, and basin authorities. Blue Water Intelligence (BWI) has developed an AI engine that transforms sparse satellite, EU Earth observation, and meteorological data into precise probabilistic forecasts up to 10 days ahead—even for ungauged rivers.

BWI’s technology uses a two-tier modeling architecture balancing speed and physical realism. The first tier, a lumped model for rapid deployment, aggregates each basin into a single “super-cell.” Recurrent neural networks capture temporal dynamics from precipitation inputs to outflow, with training in just minutes per basin. It achieves RMSE under 20% for daily discharges on gauged catchments, while physical constraints enforce mass balance and non-negative storage to prevent unrealistic drift and enable day-one production readiness.

The second tier, a semi-distributed hybrid for higher precision, discretizes basins into hydrological response units (~1–5 km²). Each unit employs RNN or LSTM layers to evolve states like surface runoff, subsurface flow, and root-zone storage.

BWI has moved into a new office in Toulouse. After a year and a half at B612 – Innovation Center, the team is now in a space better suited to day-to-day collaboration.

Release v2.13 introduces major under-the-hood improvements to BWI’s platform, alongside the deployment of a new multi-reach hydrological model. This release also brings clearer timezone handling, imperial units support, and multiple reliability and UX improvements.

BWI took part in the Carrefour des Gestions Locales de l’Eau (CGLE) 2026 in Rennes, engaging with public and private stakeholders on hydrological forecasting, flood and drought anticipation, and territorial resilience.
A recap of two days of exchanges at the heart of water management challenges.

BWI announces the appointment of Lise Ferrières as Deputy Chief Executive Officer / Chief Operating Officer (COO). Her arrival marks a key milestone in strengthening BWI’s operational structure, in support of service quality and the company’s international deployment.

BWI version 2.12 extends hydrological coverage to new regions in Nepal, Bangladesh and India, while reinforcing the reliability of the platform to support operational river flow forecasting.

At Aqua Business Days 2025 in Nîmes, BWI took part in two days of exchanges on the water–energy nexus. During a dedicated micro-pitch session, our CEO Jeremy Fain highlighted how hydrological forecasting and virtual stations support run-of-river hydropower in a context of climate change.

BWI is leaving B612 – Innovation Center in Toulouse and preparing to move to new offices in January 2026. A moment to look back on a place that supported a key phase of our growth, collaborations, and milestones.
