Sub-Grid Sampling for XP2D Extreme 

Sub-Grid samplingSampling (SGS) enables the sub-2D cell terrain data of the DEMs, TINs, and Z shapes to be used to construct the model, rather than represent each 2D face and 2D cell as having one elevation. This methodology prevents trapped water and accounts for cells partially in channels, which results in sharper 2D maps and more accurate flood extents. 

SGS is available when XP2D Extreme is enabled in 2D Job Control Settings. It is accessible to all users with existing 2D functionality.
