Surface Water Quality Risk Assessment under Climate Change Uncertainty
Session ID#: 160479
Session Description:
Climate change is increasing temperature, changing precipitation patterns, and increasing the frequency and intensity of extreme events. Heavy precipitation can mobilize contaminants stored on the floodplain, overwhelm containment and treatment works, and increase flushing of nutrients into waterways. Droughts lower water levels, concentrate contaminants, stress crops, stagnate flows, and decrease river re-oxygenation. The combination of warming and changes to precipitation patterns can exacerbate detrimental water quality outcomes including harmful algal blooms (HABs), hypoxia, among others. Given the link between climate extremes and water quality, an understanding of climate change implications for water quality is critical for the future of water quality management. This session convenes presentations on surface water quality modeling, and the evaluation of risks of surface water contamination at least partly due to shifting precipitation, temperature, or other atmospheric conditions under climate change.
