GRDL: A New Global Reservoir Area‐Storage‐Depth Data Set Derived Through Deep Learning‐Based Bathymetry Reconstruction

Water Resources Research
Reservoirs play a critical role in the global water cycle by regulating the flow of water from the environment into human systems. Accurate estimation of the area‐storage‐depth relationships for global reservoirs is essential for effective hydrological ...

Bathymetry estimation from satellite geodetic missions using gravity geologic method [PDF]

, 2018
Bathymetry information is essential in understanding the physics of the Earth and the ocean process. However, the bathymetry data are difficult to obtain at the restricted, complex and vast area. The conventional bathymetry surveys which used single beam

Generating synthetic fjord bathymetry for coastal Greenland [PDF]

, 2017
Bed topography is a critical boundary for the numerical modelling of ice sheets and ice-ocean interactions. A persistent issue with existing topography products for the bed of the Greenland Ice Sheet and surrounding sea floor is the poor representation ...

A Novel Approach for Bathymetry Estimation through Bayesian Gravity Inversion

, 2023
The bathymetry is the most superficial layer of the Earth’s crust on which it is possible to perform direct measurements. However, it is also well known that water covers more than 70% of the Earth’s surface, so an enormous expenditure of acquisition ...
