Description: The Global Reservoir Inventory of Lost Storage by Sedimentation (GRILSS) dataset provides open-source data on sedimentation and capacity loss for 1,013 reservoirs in 75 major river basins across 54 countries. This dataset serves as a critical resource for studying reservoir sedimentation, which affects the storage capacity of artificial reservoirs, with implications for water management, environmental sustainability, and infrastructure planning. The dataset consists of two main components: sedimentation data and spatial vector data, allowing for detailed geospatial analysis of reservoirs, dams, and catchments worldwide. The data is intended to support sediment management strategies, research, and future contributions from the community.
