%X Given the scarcity of in-situ water depth data in the South China Sea (SCS), a shallow water depth model HHU24SWDSCS was developed by integrating 1298 ice, cloud, and land elevation satellite (ICESat-2) trajectories and 70 Sentinel-2 multispectral images. After validation based on independent ICESat-2 depth data, the root mean square error of the model is 0.81-1.35 meters (less than 5% of the maximum depth), with an average decision coefficient of 0.91. According to independent airborne LiDAR depth measurement data validation, the depth measurement accuracy of Linyang Reef is 1.01 meters. Further comparison with existing water depth measurement models shows the superior performance of this model. The existing water depth models can have errors of tens of meters or more in island areas, so they should be used with caution, while the HHU24SWDSCS model shows good accuracy in the shallow waters of the entire South China Sea. Therefore, this model provides a reference for mapping shallow water depths near islands and provides fundamental support for research in oceanography, geodesy, and other disciplines.
