river discharge

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.

Version 2.2 of BWI’s portal features a wide range of enhancements and added features.
