Morphodynamic processes in human-impacted fluvio-lacustrine environments
Session ID#: 249374
Session Description:
Rivers and lakes continuously evolve with intertwined feedbacks among hydrodynamics, sediment transport, and geomorphology. Such morphodynamics are significantly influenced by hydroclimatological cycles, earth surface processes, and anthropogenic impacts. Since primitive human civilizations, rivers and lakes have been intensively engineered to maximize their benefits and enhance safety. Various training structures (levees, weirs or spur dikes) have been installed in rivers to regulate water depth for ship navigation and to redirect flows to prevent bank erosion. Moreover, numerous artificial reservoirs have been created through dam constructions to store fresh water for drinking, power generation, and flood control. Trapped or redirected sediment and water have significantly altered morphodynamic processes, resulting in divergent responses of these systems to hydroclimatological and earth surface processes. This session aims to bring together geomorphologists, hydrologists, and hydraulic engineers to discuss new discoveries in river and lake morphodynamics, advances in quantification methods, and associated challenges.
