Morphology

hydrographical = hydrography (semi-transparent) = hydro + graph + ical

The adjective is regularly formed from the technical noun 'hydrography' with the suffix '-ical', so the meaning is predictable once the base is known, but the base itself is specialized.

Etymology

Hydrographical comes from hydro- 'water' and graph 'to draw', the same root in photograph. So hydrographical means making maps or studies of water, which is why we use it for maps and surveys of rivers, bays, and seas.
