A rating curve is established by measuring river discharge at various water levels—without needing a weir or Venturi channel—using tools like a current meter or ADCP, and correlating these values to create a reliable stage-discharge relationship.

Industries that consume the most surface water and why it matters.

Explore Rwanda’s hydrology, its challenges, and opportunities in water management for energy, agriculture, and sustainability.

BWI’s Virtual Station approach integrates remote sensing, hydrological modeling, and machine learning to provide real-time, scalable hydrological forecasts for global water management.

Kazakhstan, the largest landlocked country in the world, faces complex hydrological challenges that significantly impact its economy, ecosystem, and population. Water resources, whilst present, are unevenly distributed across the territory and are under increasing pressure from agriculture, industry, and climate change.

This performance report assesses the effectiveness of BWI’s discharge forecast model for the Tarn River, specifically at the Countal outlet with a catchment area of 15969 km2, located in southern France. The Tarn River basin features dramatic elevation changes, descending from mountainous regions to the plains, and it passes through varied terrain, including limestone plateaus, deep gorges, and agricultural lowlands. Mediterranean and oceanic influences characterize the climate in the area. The summer droughts and Cévennes rains – with monsoon-like intense rainfall, result in very high peak flows. BWI’s model demonstrates strong performance on the validation dataset (NNSE = 0.72), with very well-captured baseflow and peak-flow occurrences.

In the latest performance report, we assess the effectiveness of BWI’s discharge forecast model for the Bourbre River, specifically at the Vernay outlet, which covers an area of 313 km². The drainage basin of the Bourbre river, located in southeastern France, is characterized by hills, plateaus overlooking valleys, and extensive marshes. The climate in the region is temperate, with both mountainous and continental influences due to its proximity to the Alps and the Rhône Valley. The model demonstrates strong performance on the testing dataset (NNSE = 0.73), accurately simulating baseflow. The underestimation of river discharge during summer months reflects the limited resolution of the available meteorological data.

The 75th International Astronautical Congress in Milan was a pivotal moment in the ongoing dialogue about the role of space exploration in building a sustainable future. For companies like BWI, IAC 2024 offered a glimpse into how space data can revolutionize hydrological monitoring and contribute to a more sustainable world.

At the 12th World General Assembly of the International Network of Basin Organizations (INBO), BWI had the privilege of joining global leaders in water resource management to discuss one of the most pressing challenges of our time: climate-resilient basin management. Held in Bordeaux, France, this event not only marked INBO’s 30th anniversary but also offered an invaluable opportunity to learn from experts and engage in meaningful dialogue on innovative solutions for sustainable water practices.
