How can climate change affect waterways management?

• A. By increasing the number of navigational locks needed
• B. By causing alterations in water levels and flooding
• C. By improving water temperatures for wildlife
• D. By decreasing sediment buildup in waterways

Answer: (B)

Climate change has a significant impact on waterways management, particularly through alterations in water levels and flooding. As global temperatures rise, patterns of precipitation and evaporation change, leading to increased rainfall in some areas and prolonged droughts in others. This variability can cause rivers and lakes to experience fluctuating water levels, potentially leading to situations where waterways become too shallow for navigation or, conversely, too full, resulting in flooding. Flooding can threaten infrastructure, disrupt ecosystems, and increase sediment and pollutant runoff into waterways, which complicates management efforts. Effective waterways management must take these changing water levels and the potential for extreme weather events into account, as they directly influence water quality, aquatic habitats, and the safety and effectiveness of navigation routes. Thus, recognizing and preparing for the impacts of climate change is essential for sustainable waterways management.
