Global lakes depth-area-volume relationship with 0.1m resolution

Our research presents comprehensive approaches to modeling the depth-area-storage relationships of over 1.4 million global water bodies with a high accuracy of 0.1 meters. It addresses critical ecological challenges exacerbated by human activities, like climate change and industrial impacts on freshwater systems. The study employs a dual methodology, combining polynomial equations (first to fifth order) and a power function, offering representations of area, depth, and volume relationships in water bodies. Our advanced approaches enhance the precision in predicting water bodies’ bathymetric dynamics, crucial for ecological modeling and sustainable water management. The research's significant contribution lies in laying the foundation for advanced hydrodynamic and water quality models, important for monitoring and predicting ecological changes in freshwater ecosystems.
