RLR_SS2 | RESERVOIR SEDIMENTATION: PROCESSES AND MANAGEMENT STRATEGIES


Theme:
Rivers, Lakes and Reservoirs (RLR)

Short description on the session:
Sediments depositing in lake and reservoirs are considered as a big threat. From the technical point of view, sedimentation reduces water reservoir storage capacity and therefore risk a stop of hydropower production or valuable water supply for irrigation or domestic and industrial consumption. Indirect consequences such as flood defense and drought control will also be affected negatively. From the ecological point of view fish and wildlife conservation, water quality as well as recreation functionalities are at risk, if depositing sediments reduce the active storage volume of reservoirs. In addition, a dam structure without active sediment management destroys the sediment balance throughout the water system and may cause significant infrastructure and environmental damages both upstream and downstream of the dam. This special session will trigger a thorough discussion on the sustainable use of the water reservoirs by presenting contributions related to understanding hydraulic, biological and sediment transport processes in water reservoirs and developing effective strategies to counter sedimentation. Current research from laboratory, numerical, and field will be presented.
