The study focused on assessing flood risks in the Sperchios River basin in Greece. Researchers used computer models to estimate how much water would run off the land during heavy rain, and then simulated how this water would flow through the river. They found that during normal conditions, the river could reach a peak flow of 1969 cubic meters per second. However, if the land was already wet, the peak flow could increase by 40% to 2756 cubic meters per second. This information can help improve flood forecasting and early warning systems in the area.
