The Danube River potentially conceals not only bridge remnants and unexploded ordnance, but also valuable thermal spring resources. Current focus needs to shift towards improved rainwater harvesting and management. Rather than quick drainage, rainfall should be retained locally and carefully reintroduced into underground water systems. This approach is crucial for replenishing groundwater reserves. Experts emphasize the importance of this change in strategy to sustainably utilize the river’s potential. Proper water management is key to unlocking these hidden resources and ensuring long-term environmental health. This holistic approach acknowledges the multifaceted nature of the river’s value.
