hydrographically
Regarding water mapping
In terms of hydrography—the science of measuring and mapping bodies of water.
The term describes how something relates to water features like depths, currents, coastlines, and underwater topography: The region is hydrographically complex, with numerous channels and shifting sandbars.
Used primarily in technical and scientific contexts.
