Tarn

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.
