Impacts of global change and extreme events on hydrological and biogeochemical systems
Session ID#: 247908
Session Description:
Disturbances caused by global change and extreme events such as droughts, hurricanes, wildfires, and heat waves are increasingly challenging hydrological and biogeochemical systems worldwide. These press and pulse disturbances disrupt hydrological, biogeochemical, and ecohydrological processes, creating complex interactions and cascading effects on water availability and quality. Understanding the vulnerability of these systems to such disturbances is paramount for effective adaptation and resilience-building efforts. We seek contributions that explore how disturbance caused by global change and extremes alter hydrological and biogeochemical fluxes, flow pathways, and in-stream processes from catchment to global scales. We also encourage submissions that examine broader implications for water resources management and ecosystem health and offer insights into building adaptive capacity. By quantifying the vulnerability of watersheds to natural disturbances and identifying strategies to enhance resilience, this session aims to inform evidence-based decision-making and promote sustainable land and water management practices.
